IMPORTANT SAFETY INSTRUCTIONS

- The National Electrical Code requires the use of a transfer switch or other suitable transfer equipment whenever a portable generator is connected to a building's electrical system. Transfer switches isolate generator power from utility power and prevent backfeeding of electric power into the utility system.

DANGER

Fire and electrocution hazard.

DO NOT connect to a building's electrical system unless the generator and a transfer switch have been properly installed and the electrical output has been verified by a qualified electrician. The connection must isolate the generator power from utility power and must comply with all applicable laws and electrical codes. Failure to properly isolate the generator power could cause property damage and create a dangerous backfeed of electricity which could kill or seriously injure utility workers.

WARNING

Use approved transfer

switches and equipment to isolate generator power from utility power. Using non-approved transfer switches can result in death, serious injury, and equipment damage.

- Installation and maintenance of this transfer switch must be performed by a qualified electrician in accordance with applicable electrical codes. Some jurisdictions may require the installation to be inspected by local authorities. Keep all relevant installation, inspection, and maintenance information.

WARNING

Using transfer switches that

are improperly installed and maintained could result in electrocution or fire, which can cause death or serious injury.

DANGER

Do not wire or operate the

transfer switch or any electrical equipment while barefoot, with wet hands or feet, while standing in water or in wet conditions. Doing so will create a dangerous electrical shock hazard that will result in death.

DANGER

Handle transfer switches

with care during installation. Never mount or wire a damaged transfer switch. A damaged transfer switch could malfunction and create electrical hazards that could result in death, serious injury, and equipment failure.

WARNING

Only licensed and qualified

professional should wire and install transfer switches. Improper installation can result in death, serious injury, and equipment or property damage.

- Always ensure that the main circuit breaker in the load center is in the OFF position before installing the transfer switch, changing the electrical source, or performing maintenance.

DANGER

Risk of Electrocution. Turn the

main circuit breaker in the load center OFF before connecting circuits to the transfer switch. Contact with live terminals will result in severe electric shock, personal injury, and death.

DANGER

In case of an electrical

emergency, immediately shut the power OFF. If necessary, separate the victim from live conductors using non-conductive items like a PVC pipe or wooden broomstick. If the victim is unconscious administer first aid and get medical assistance immediately. Failure to act promptly will result in death or serious injury.

SAFETY INSTRUCTIONS FOR USING PORTABLE GENERATORS

- Portable generators should only be used outside and far away from vents, windows, and doors.

NOTICE

Install battery-powered carbon

monoxide detectors or plug-in carbon monoxide detectors with battery back-up in living areas.

DANGER

Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell.

NEVER use inside a home or garage, EVEN IF doors and windows are open.

Only use OUTSIDE and far away from windows, doors, and vents.

• This transfer switch should only be connected to a generator with neutral floating.
  ● Always turn the generator off before connecting or disconnecting the power cord.
• Monitor the wattage meters and balance electrical loads to avoid tripping the generator's circuit breakers or hindering the generator's performance.

NOTICE

Do not connect branch circuits

with appliances or systems that exceed the switch or the generator's load capacity. Exceeding the load capacity could damage the switch, the generator, and any connected devices.

ELECTRICAL

CHOOSING LOAD AND TRANSFER CIRCUITS

- With the help of a qualified electrician, decide which branch circuits inside the load center will use generator power when the switch is operational. Choose up to six circuits that include 120V appliances and equipment and up to two circuits that include 240V appliances and equipment.

NOTE: If you are unsure about the voltage requirement for a device connected to a branch circuit, remove that device before connecting the branch circuit to the transfer switch.

- After identifying the branch circuits, select corresponding transfer circuits based on amperage and wattage. Branch circuits with 15A breakers can be paired to one of six transfer circuits with 15A breakers. Branch circuits with 20A breakers can be paired to one of two transfer circuits with 20A breakers. Try to distribute loads with similar wattage requirements equally on either side of the switch. Refer to Wattage Capacity later in this section.

NOTE: Do not pair circuits if the amperage rating for branch circuit exceeds the rating for the transfer circuit.

WATTAGE CAPACITY

Be certain that the generator can produce enough start-up and running wattage to power all of the items connected to the circuits you select. Wattage information for most devices can be found directly on the unit.

NOTICE

Do not overload the generator's

capacity. Exceeding the generator's wattage/amperage capacity can damage the generator and/or electrical devices connected to it.

Starting watts are typically higher than running watts since some electrical motors draw more power when first started. Use the watt meters on the transfer switch to monitor start-up surges and ensure the generator is not overloaded.

For optimal performance the loads on the left side of the transfer switch (circuits A-E) should be balanced with the loads on the right side (circuits F-J) to within a 1000W. If necessary turn off the generator, ensure that the main circuit breaker in the load center is in the OFF position, and rebalance the load.
