Installation Procedure cont.
Input Wiring
At the power source, install two, single pole, high inrush, circuit breakers (60A max) following proper wire sizing and conduit guidelines
(per NFPA 70 2011 Article 220, Chapter 9 and local/national codes).
Check that input power to the panel is off or disabled before installing input cabling and install customer provided strain relief to one of
three knockout locations located near the access panel on the top, side, and bottom of the chassis.
13. Open input panel door shown in Figure 4a.
14. Feed input cable through strain relief and label all wiring for clear identification.
15. Secure LINE 1 to top location of terminal block, NEUTRAL 1 to second position from the top, LINE 2 to the bottom position, and
NEUTRAL 2 to the 2nd position from the bottom of the input terminal block (see Figure 4a and 4b). To secure wires, follow figure
4a: (1) Strip wire to 18mm [0.70in]; (2) Fully insert wire into terminal block with latch in the open (vertical) position; (3) Fully de-
press latch into the closed (horizontal) position.
16. (Optional) For low power test purposes only, power may be fed to the unit via two IEC 320-C14 power enty modules (labeled L1
Test and L2 Test) found to the right of the input terminal block. Max power per test feed is 10A. After connecting inputs, close
input panel door and secure with captive fasteners. This door must be closed prior to supplying power to the unit. Failure to do
so can result in severe electric shock.

To prevent possibility of electrical
shock, both power sources must
be disconnected from AC Edge
before servicing. Installation
must meet all local codes and
jurisdictions.
