Load Modules
Load Modules for 3.5 to 12 kVA units offer a variety of
power receptacles when used in conjunction with the
Configurable Distribution. Each Load Module includes:
1. Circuit Breaker
2. Green output receptacle(s) power indicator
3. 1 or 2 Output Receptacles.
Hard Wire (terminal block) Load Modules provide a
knockout to attach flexible conduit (see drawings to the
right). Use no more than three feet of conduit to avoid
attachment points required by national and local codes.
Terminal compression lugs accept wire size 42 to #14
AWG. Select wire size based on UL 1778 and NEC. See
Table #3 below for circuit breaker provided. Tighten each
connection based on wire size as follows: 10 to 14 AWG to
35 Ib.-in., 8 AWG to 40 lb.-in., 4-6 AWG to 45 lb.-in., 2-3
AWG to 50 lb.-in.
See Power Management for details on Power
Management Load Modules.

HARDWIRE NOTES
Use flexible metal or liquid-tight metal conduit only.
For conduit lengths longer than three feet, refer to NEC article 350-4 or 351-4 for
securing conduit.
Use knockouts for conduit attachment. DO NOT drill into UPS or load module.
Use wire sized in accordance with NEC 310-16 and the output breaker amperage.
