Unison ERn enclosures have conduit knockouts on the top and bottom for incoming power and control
wiring. Alternatively, conduit knockouts are located on both sides of the rack for control signal wiring
as needed. Signal and power wiring must be run in separate conduit in accordance with national and
local codes.
Control and power must be run in separate conduit.
