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.

•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.

NOTE: The surge protective device must be installed in an accessible location as described in the NEC®.

NOTE: The neutral connection is not present on 3-wire, 3-phase wye ground or 2-wire single- phase mid-point ground power systems. For these systems, bond the neutral and ground lugs together in the SPD. For installing wiring see Figures 3 through 5.

NOTE: See “Terminals, Wire Size, and Installation Torque” section for the acceptable wire size and installation torque on page 10.

NOTE: Always install the SPD on the LOAD side of the main Overcurrent Protection Device (OCPD).

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

Confirm the SPD voltage rating on the module or nameplate label is the same as the operating voltage.

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

Follow the steps listed below when making wiring connections.

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.Identify proper location for surge protective device. Locate as close as possible to the panel being addressed so the wires are as short as possible. Mount unit securely.

4.Install in accordance with National Electrical Code® (NEC®) and local electrical codes for overcurrent protection recommendations and wire ampacity considerations.

5.Twist conductors 1/2 turn or more for every 12 inches of length. Do not loop or coil wires. Be sure to maintain adequate wire bending space per NEC.

6.If the remote signaling contacts of the diagnostic display panel are to be used, refer to the section, “Dry Contacts”, on page 18 for wiring instructions.

7.On a high-leg delta installation, note the high leg connection per wiring diagram. See Figure 5.

8.Replace all devices, doors, and covers, including the line barrier for the optional integral disconnect, before turning on power to the equipment. If the SPD is properly installed and functioning, the green LED indicators on the display will be lit.
