8.Dress the power cables so the ribbon cables will not be pinched, crushed, or other wise damaged when the cover is installed. If connecting Dry Contacts, it may be effective to install communication lines prior to power conductors.

9.Connect the unit to the service panel through the UL approved conduit with anti-short bushings as follows:

a.Strip about 3/8" (.95 cm) of the connecting wire insulation from each wire. Note: Terminal wire size range is #8 AWG to #1 AWG. The recommended wire size for phase, neutral, and ground is #6 AWG.

b.Twist the end of each connecting wire so it is uniform.

c.Slide the connecting wires through the hole in the side of the SPD.

d.Loosen the screws at the terminal lugs and insert the appropriate wire into the hole in each terminal lug. Tighten the phillips-head screw down onto the wire and torque to 18 inch-pounds. Note: The connecting wires should be kept as short as possible to enhance the performance of the SPD.

e.Connect a wire (in conduit) to the safety ground bus of the distribution panel, and to the ground connection of the SPD as shown in Figure 2, and as marked on the unit. Proper grounding is essential, use a green wire or yellow/green striped wire for the ground connection. Torque the phillips-head screws to 18 inch-pounds.

f.Connect a wire (in conduit) to the NEUTRAL bus of the panel and to the NEUTRAL connector of the SPD as marked on the unit. Use a white wire or mark with a white band for the neutral connection. Torque the phil- lips-head screws to 18 inch-pounds.

g.Connect a wire (in conduit) to each phase (HOT) feed on the LOAD side of the circuit breaker in the AC dis- tribution panel. Use a 30A to 40A (40A preferred) circuit breaker with the appropriate number of poles. Turn the circuit breaker OFF before making any connection. Refer to Figure 2 to identify the lug phase connections when making phase connections.

For answers to questions about installation, call APC’s Customer Service Department at: 800-800-4APC.

**Always Install the SPD on the LOAD side of the main disconnect**

After all connections have been made and no hazards exist, restore power to the AC distribution panel or breaker. If the SPD is installed and functioning properly, the green LED phase indicators on the front panel display will be lit and there will be no audible or visual alarms.

10.Use an AC voltmeter to check all voltages to ensure that the proper unit type has been installed for the service rating being protected.

11.Carefully install the front cover on the chassis. Ensure that the ribbon cables are dressed in a manner that they are not pinched or crushed when the cover is installed.

12.Tighten the captive screws that secure the cover to the chassis.
