4.3Conversion From Cord-Receptacle to Hardwire
Two wiring access panels on the front of the 3U POD allow access to the wiring compartments. Each access door is retained using four Phillips head screws.
1.Remove the eight Phillips head screws from the wiring access panels on the front of the unit. Save the screws.
2.Holding the panels aside, disconnect the three wires that connect each panel to the internal terminal block. Remove the panels. DO NOT LOOSEN THE UPPER TERMINAL BLOCK

Properly grounded (earthed) equipment provides multiple benefits
High quality ground (earth) connections are required for the equipment ground conductors (protective earth) and grounding electrode conductor (power system earth connection) to reduce electrical noise and provide for safe operation of the UPS and connected loads. Conduit used alone without a ground- ing conductor wire is not an acceptable connection. Size ground (protective earth) conductors equal to circuit conductors.
For wiring information, refer to Table 2.
