Weights From the 2011 season the method of calculating the Mass in Running Order (MFC) and user payback figures has changed in order to bring it in line with European Vehicle Directives.
Allowances for essential equipment (e.g. gas cylinders previously allowed for in the other payload are now contained within the MPO. A provision for a ensure battery which used to be within the essential equipment payload has now been included within the personal effects payload allowance.
Although the method of calculation has changed, the overall effect is that the amount of supply available to the customer has remained the same. It is just calculated in a different manner
\* Estimated
Bed Sizes: Please note that the front double bed sizes quoted are for sealing configurations without chest of drawers. The front double bed width for a layout with a chest of drawer's fit was reduced by 0.4m(14") from that stated.
Awing sizes: Due to drawing owning designs and sizes the awning sizes other are approximate only. Specific awning sizes must be continued by your dealer or owning manufacturer over year to purchase.
** The dimensions given are approximate due to slight variations in suspension rule heights, loading conditions and 7/8 pressures.
Customers should verify the actual dimensions at their fouring canvas before committing to anything that could be impacted by these dimensions.
Please note: Any dealer if option is will choose the metal payment available to the user of the caravan. If you require action at payback it is possible to upgrade the MFM to the upper limit. Please clarify your Sare caravan dealer for more information.

EC155 Power Control System
1 Key Features
150W (-12A) combined Power Converter / Battery Charger - Converts the 230V mains supply into 12v DC power to run the leisure equipment and charge the battery.
Low current switching reduces voltage drop in the circuit and improved circuit fusing provides better protection for the harness and equipment.
Links to the EC50 series LED Control Panel to provide simple but intelligent control of the 12v equipment and built in over discharge software protects the leisure and vehicle batteries.
2 System Overview
The following diagram shows the typical configuration of the EC155 system. The key component is the EC155 power supply unit (PSU), which is the hub of the system and provides connectivity to the ancillary components and the EC50 series control panel.

3 Power Supply Details
For the safe operation of all electrical equipment within your Leisure Vehicle it is important that you read and fully understand these instructions. If you are unsure of any point please contact your dealer / distributor for advice before use.
The following diagram shows the EC155PSU layout.
WARNING: Under heavy loads the EC155PSU case may become hot. ALWAYS ensure the ventilation slots have a clear flow of air. Do not place combustible materials against / adjacent to the EC155PSU. The PSU will shutdown if overheated and will restart automatically when cool

3.1 Battery Charger / Power Converter
The EC155PSU incorporates a fixed voltage battery charger / power converter. The battery charger / power converter also powers the leisure equipment when the mains supply is connected. This module supplies 13.8v DC to the leisure equipment up to a maximum of 12 Amps (165 Watts), therefore the available power is distributed between the leisure load and the battery, with the leisure load taking priority as per the following example:
| Leisure load Available | power for battery charging |
| 3A 9A | |
| 6A 6A | |
| 9A 3A | |
| 12A 0A |
3.2 Residual Current Device & miniature Circuit Breakers

The Residual Current Device (RCD) is basically provided to protect the user from lethal electric shock. The RCD will turn off (trip) if the current flowing in the live conductor does not fully return down the neutral conductor, i.e. some current is passing through a person down to earth or through a faulty appliance.
To ensure the RCD is working correctly, the test button should be operated each time the vehicle is connected to the mains supply (see section 5.1)
The Miniature Circuit Breakers (MCB's) operate in a similar way to traditional fuses and are provided to protect the wiring installation from overload or short circuit. If an overload occurs the MCB will switch off the supply. If this occurs you should investigate the cause of the fault before switching the MCB back on.
The following table shows the rating and circuit allocation for the three MCB's
| MCB | Rating | Wire Colour | Description |
| 1 10 Amps | White | 230v | Sockets |
| 2 10 Amps | White (Yellow for heater) | Extra 230v | Sockets / Heater |
| 3 | 6 Amps | Black (Blue for water heater) | Fridge / Water Heater / 12v Charger (Internally connected) |
3.3 Fuses
WARNING: When replacing fuses always replace a fuse with the correct value. NEVER replace with a higher value / rating as this could damage the wiring harness or appliance. If a replacement fuse 'blows' do not keep replacing the fuse as you could damage the wiring harness or appliance. Please investigate the fault and contact your dealer.
The following table shows the fuse allocation for the 12 fuses fitted to the EC155PSU.

3.4 Battery
A) Type / Selection
For optimum performance and safety it is essential that only a proprietary brand LEISURE battery is used with a typical capacity of 75 to 120 Ah (Ampere / hours). A normal car battery is NOT suitable. This battery should always be connected when the system is in use.
The EC155PSU is designed to charge standard lead acid leisure batteries, however it may be used with Gel batteries depending on their composition. Please consult the battery documentation for further advice.
The battery feed is fitted with an inline fuse between the battery and the electrical harness, and is usually located immediately outside the battery compartment or within 500mm of the battery. The maximum rating of this fuse is 20A per battery.
B) Installation & Removal
Always disconnect the 230v mains supply and turn the EC155PSU charger switch to the OFF (0) position before removing or installing the battery.
When connecting the battery, ensure that the correct polarity is observed (black is negative [-] and red is positive [+]) and that the terminals are securely fastened. Crocodile clips must not be used.
WARNING: Explosive gases may be present at the battery. Take care to prevent flames and sparks in the vicinity of the battery and do not smoke.
C) Operation / Servicing
Under normal circumstances it should not be necessary to remove the battery other than for routine inspection of the terminals and "topping up" of the battery fluid where applicable. Please see instructions supplied with the battery.
Note: Do not over discharge the battery. One of the most common causes of battery failure is when the battery is discharged below the recommended level of approximately 10v. Discharging a battery below this figure can cause permanent damage to one or more of the cells within the battery.
To prevent over discharge, the EC155PSU in conjunction with the EC50 series control panel incorporates a battery protect circuit that warns and then disconnects the batteries when they fall below the following conditions:
| Battery Voltage cut off | Action after cut off Notes | |
| Vehicle 10.9v Batter | selection is changed from Vehicle battery to Leisure battery. If the leisure battery is below 9v then a further warning will occur (see below). | This cut off level is designed to protect the vehicle battery from over discharge. The 10.9v level ensures there is sufficient power in the battery to run the vehicle electronics and start the vehicle. This cut off only applies to power drawn from the battery by the leisure equipment; it will not protect the battery if you leave the vehicle lights on. |
| Leisure 9v Power is turned off This is an emergency cut off level to protect the battery from severe damage. You should not rely on this cut off level during normal operation, but manage your power consumption to a discharge level of 10v. This cut off only applies to power drawn from the battery by the leisure equipment that is controlled by the control panel power switch; it will not protect the battery from discharge by the radio or other permanently connected equipment. | ||
