QUICK START GUIDE
Verify all AC breakers are off!
The unit's input is designed for up to four 8 AWG conductors to be terminated in the AC mains breaker, neutral ter-
minal block and ground location(s) within the AC termination area at the top of the unit. The AC input is brought
into the unit at the bottom of the unit through industry standard ¾" water-tight conduit and the wires are routed
up to the top AC termination area.
1.
Attached industry standard ¾" water-tight conduit at the bottom of the unit and run the AC input wires
through the conduit and route to the top of the unit where the AC termination area is located.
2. Strip the jacket off each of the conductors to expose bare conductor as follows: 0.5 inches (13 mm) for L1 and
L2; 0.35 inches (9 mm) Neutral and Ground

3. Connect the ground wire to the chassis stud with
the provided ring terminal. Torque the nut to 30 in-
lbs.
4. Connect provided bond wire between neutral bus
assembly and chassis stud. Torque the terminal
block screw to 25 in-lbs using a flat bladed screw
driver and 30 in-lb on the chassis stud.
5. Connect neutral conductor to the grounded
terminal block. Torque the terminal block screw to
25 in-lbs using a flat bladed screw driver.
6. Pull wire to verify.
7.
Connect the Line 1 wire to the lower position of
the 2-pole circuit breaker. Refer figure 12.
8. Torque the screw compression fitting to 35 in-lb
for 10 AWG or smaller, 40 in-lb for 8 AWG using a
flat bladed screw driver.
9. Pull wire to verify.
10. Connect the Line 2 wire to the upper position of
the 2-pole circuit breaker. Refer figure 12.
11. Torque the screw compression fitting to 35 in-lb
for 10 AWG or smaller, 40 in-lb for 8 AWG using a
flat bladed screw driver.
12. Pull wire to verify.
