ETC Unison ERn Wall-mount Control Enclosure - Manual (Page 18)

14 Unison ® ERn Wall Mount Enclosure Installation Manual
Rough-in Line and Control Conduit and Wiring
The ERn enclosure requires line power and control wire terminations. For installation
convenience all terminations are accessible from the front of the rack. A single phase line
power and all required control wires may be pulled through any of the conduit knockouts
provided, or other labeled locations.
Step 1: Plan wire entry to the rack. See “Wire Routing and Specification” on page 9.
Step 2: Remove the required conduit knockouts from the rack or punch new conduit
holes. Pay special attention to the rack design so that you do not punch conduit
access in a place that will prevent components from being installed.
Step 3: Install conduit fittings or insert lining materials in the new opening.
N o t e : Control (signal) wiring and power wiring must be run in separate conduit in
accordance with local code.
C A U T I O N : Wire openings must have fittings, bushings, grommets or fish paper lining material
to protect wire and cable insulation from damage by sharp metal edges.
