Alternate Hardwire Installation
7
4.3 Conversion 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
SCREWS USED FOR INTERNAL WIRING.
3. Install flexible conduit with wiring to the applicable conduit entry holes on the side or rear of the
unit.
4. Terminate the wiring to the internal terminal blocks. The wiring compartments provide terminal
blocks to connect Line, Neutral, and Ground for both the UTILITY input and the LOAD output.
5. When wiring is complete and secure, install the two blank hardwire access plates supplied with
the unit, using the eight screws removed in Step 1.
6. The unit is now ready to use.
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.
