2.6.1 Wiring the Enclosure Utility Service
The following procedure does not apply to either the rack mount (RM) or shelf mount
models (SM) which plug into a receptacle in the rack or enclosure.
Utility power enters the enclosure through a 7/8" diameter opening at the bottom of
the APX enclosure. The enclosure accepts a standard conduit fi tting. When used in
conjunction with the PED-M metered, ground-mount enclosure, utility power enters
through a dedicated raceway.
CAUTION!
Contact your local utility for approval before you install the power supply and connect to utility
power. All work should be performed by qualifi ed service personnel in compliance with local
electrical codes.
NOTE:
UL and NEC require the installer to connect a service disconnect switch (UL listed) between the power
source and the Alpha power supply.
