ROUTE CONTROL WIRES
Maximum length of wiring (18 gauge) for all connections on the RSBus is 1500 feet (457 meters). Wires should be color-coded, with
a temperature rating of 95
º
F (35
º
C) minimum, and solid-core (Class II Rated Wiring). All low voltage wiring must enter unit through
field-provided field-installed grommet installed in electrical inlet.
Any excess high voltage field wiring should be trimmed and secured away from any low voltage field wiring. To facilitate a conduit, a cutout
is located on the bottom of the control box. Connect conduit to the control box using a proper conduit fitting.
