Step 5 - Wire AC Power to the Unit
and Ground the Unit
Observe the following guidelines when wiring AC power:
• The terminal block accepts up to 3.31 mm
2
(12 AWG) wire.
• The recommended tightening torque is 1.3 newton-meters (12 in-lb).
• Verify that the input power to the unit corresponds to the unit voltage and frequency
and that the input supply is of sufficient capacity to support the input current
requirements. Refer to Appendix A, Technical Specifications.
• Size the AC line conductors for the unit rating and in accordance with all applicable
local, national, and international codes.
Use the following procedure to wire AC power to the unit. Grounding instructions are
provided in Section 5.1.
Remove the cover by loosening the four cover screws. Note that the display ribbon cable
is designed to disconnect from the main unit when the cover is removed as shown in
Figure 5.1.

Removing the Cover
ATTENTION: If the distribution system capacity exceeds the unit’s
maximum symmetrical fault short-circuit current of 10,000 amps,
additional impedance should be added to the AC line supplying the unit
to limit available current in the event of a fault. Failure to observe this
precaution could result in severe bodily injury or loss of life.
