APC MODULAR PANEL PRODUCTS Surge Protective Device (SPD)

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

·Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E.

·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.

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

WIRING Note: Prior to mounting the SPD, verify that the device has the same voltage rating as the power distribution system in which it is installed by comparing the nameplate voltage or model number on the SPD with the nameplate of the electrical distribution equipment.

Follow steps 1–5 to make wiring connections.

1.Turn off all power supplying this equipment through the Panel Circuit Breaker or Primary Disconnect before working on or inside the equipment. (For additional protection, an integral switch may be used)

2.Mount the SPD as close as possible to the panelboard being protected.

3.Connect the SPD to the panelboard using an approved wiring method. The connecting wires should be twisted (1/2 turn for each foot of length) together and kept as short as possible (do not loop or coil wires) to

enhance the performance of the device. See page 8 for the recommended wire size and installation torque. For wiring diagrams, see figures 3 thru 6.

a.Connect the ground wire to the GROUND bus of the distribution panel. Where applicable, connect ground to the SPD module.

b.Where applicable, connect the neutral wire to the SPD module.

c.Be sure the circuit breaker is open (OFF) prior to making any connections of any kind. If a circuit breaker or circuit breaker space is not available, connect to the electrical panel bus and then to an integral disconnect utilizing the 3M or 10ft tap rule. (See NEC 240.21(B)(1)(4)). Be sure the disconnect is open (OFF) and the circuit is de-energized before making any connections. Connect a wire (in conduit) to each phase (HOT) terminal on the LOAD side of a circuit breaker. Refer to the markings on the device when connecting the phase, neutral, and ground conductors. Fuses are not recommended for protection unless the fuses are specifically designed for use in an SPD application.

NOTE: On a high-leg delta installation, the high-leg of the power system must be connected to phase B of the SPD.

4.After all connections have been made, reinstall any barriers that have been removed, close the door or replace the cover.

5.Restore power to the equipment as required. If the SPD is properly installed and functioning, the green LED indicators on the display will be lit.

If you have any questions pertaining to the installation, contact your APC representative.

NOTE: Always install the SPD on the LOAD side of the main disconnect.
