3.5.4 Hardwiring the Input and Output wires to the terminal block on the UPS
module when using the UPS without the Isolation Transformer module.
CAUTION
- To reduce the risk of fire, connect the UPS Utility input to a branch
circuit with an over-current protection of 40 amperes in accordance with the
National Electric Code, ANSI/NFPA 70. Use No. 8 AWG, 60
°
C copper wire. The
UPS OUTPUT must be connected to an over-current protection device (circuit
breaker) of 30 amperes in accordance with the National Electric Code, ANSI/NFPA
70. Use No. 10 AWG, 60
°
C copper wire and apply 22.1lb-in of torque force when
connecting to the terminal blocks.
3.5.4.1 INPUT terminal block when using the UPS system without the Isolation
Transformer module. The Utility Input must be hardwired.
1. Connect a wire from the Utility power to the Utility input terminal L12.
2. Connect a wire from the Utility power to the Utility input terminal N1.
3. Connect a wire from the Utility power Ground to the Utility input terminal G1.
3.5.4.2 OUTPUT terminal block when using the UPS system without the Isolation
Transformer module
1. Connect a wire to the Output terminal L21.
2. Connect a wire to the Output terminal N22.
3. Connect a wire to the Output terminal G2.
3.5.4.3 Application
D:
1. Utility Input: 208/240VAC must be hardwired (see Section 3.5.4.1 for
wiring).
2. UPS Output: 208VAC or 240VAC.
3. Output Receptacle Box (ED6-208RB): 1)-L6-30R, 1)-L6-20R and 4)-6-
15/20R (see Section 3.5.2.3 for wiring the receptacle box to the TR
OUTPUT terminal block).
4. No Isolation Transformer module or Maintenance Bypass Switch.

3.5.4.4 Application
E:
1. Utility Input: 208/240VAC must be hardwired (see Section 3.5.4.1 for
wiring).
2. UPS Output: 208VAC default, or 240VAC optional, hardwired (see Section
3.5.4.2 for wiring).
3. No Isolation Transformer module or Maintenance Bypass Switch.
3.6.
Connecting the RJ-45 cables for the Maintenance Bypass
Operation (Qualified Service Personnel Only)
3.6.1 Connect one end of Cable A (RJ-45 cable) to the bottom RJ-45 connector
on the UPS module. Connect the other end of Cable A to the first RJ-45
connector on the left hand side of the Isolation Transformer module (see
Cable A below).
3.6.2 Connect one end of Cable B (RJ-45 cable) to the top RJ-45 connector on
the UPS module. Connect the other end of Cable B to the second RJ-45
connector on the left hand side of the Isolation Transformer module (see
Cable B below).
3.6.3 See section 3.7.8 to perform the Maintenance Bypass procedure.
