Precautions

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E or CSA Z462.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Turn off all power supplying this equipment before working on or inside equipment.
• Always use a properly rated voltage sensing device to confirm power is off.
• Replace all devices, doors and covers before turning on power to this equipment.
• This equipment must be effectively grounded per all applicable codes. Use an equipment-grounding conductor to connect this equipment to the power system ground.

Failure to follow these instructions will result in death or serious injury.

Installation

Find a suitable location for the HEPD80 and flush mount kit. These locations are typically above or below the load center/power panel (see Figure 1). The mounting location should be free from obstructions in the wall that would prevent the installation of conductors, e.g. stud(s) or other obstructions.

1. Turn off all power supplying this equipment before working on or inside any enclosure containing this equipment.
2. Confirm the SPD voltage rating and configuration is the same as the system voltage and power system configuration to which it will be connected.
3. Place the cut-out template provided flat against the wall positioned at a minimum of three, to a maximum of, five inches below the bottom of the load center and properly aligned with the available knockout. See Figure 1.
4. Mark the locations of the four mounting holes and the area of the wall to be cut out. See Figure 1.

3 in. (76 mm) Min. 5 in. (127 mm) Max. Mark holes Trace opening

1. Using a saw or a knife, cut out an opening for the Surge Protective Device (SPD).
2. Install the four wall anchors into the marked mounting holes. (No drilling is required).
3. Remove the knockout in the bottom of the load center that best fits the location of the SPD. See Figure 2.

1. Straighten the SPD wire coil (A), as shown in Figure 3.
2. Remove the conduit locking nut (B).

1. Cut the flexible conduit to the appropriate length to accommodate the installation.

Note: The length of conduit will be the same as the offset distance from the bottom of the load center, as identified in step 1. See Figure 1.

Example: If the offset distance from the bottom of the load center is three inches, the conduit length should also be three inches.

1. Install the two flex conduit fittings onto each end of the flex conduit.

See Figure 7.

1. Thread the flex conduit assembly over the SPD wires and attach to the coupling of the SPD assembly.

Note: Finger tighten the conduit coupling and tighten for an additional 1/4 turn. See Figure 8.

1. Thread the wires and SPD assembly through the hole in the wall and through the knockout of the load center. Slip the lock nut over the wires and secure the conduit in place, as shown in Figure 9.
2. Secure the mounting bracket to the wall using the four screws provided. See Figure 9.

1. Connect the ground wire from the SPD to the grounding lug located in the power panel. See Figures 10 and 11.
2. Connect the SPD black wires now located in the power panel to a 20 amp two-pole circuit breaker. See Figures 10 and 11.
   NOTE: Confirm that the two-pole circuit breaker is in the OFF position prior to installing the wires.
3. Connect the SPD white wire now located in the power panel to the neutral bus. See Figures 10 and 11.

Operating and Testing 1. Turn on the two-pole circuit breaker feeding the SPD.

1. Replace all devices, doors and covers.
2. Restore power to the power panel. If the electrical and grounding sections are installed correctly the green lights on the AC section of the SPD will be on. If neither of the lights are on, turn off the power and review all steps of 'mounting'.
3. Periodically check the green lights on the AC surge suppression device to ensure that they are illuminated. If one or both the green lights go out, it indicates that AC power or suppression has been lost.

Align with the knockout to be used Align with the marked location on the wall. Must be positioned at a minimum of three inches below the load center.
