nstallation and Wiring
The A350E Cooling Control is housed in a compact
NEMA 1 plastic enclosure designed for standard
35 mm DIN rail mounting. Four key-slot mounting
holes on the back of the control case are provided if
surface mounting is required. The A350E may be
connected to a Y350R, as well as other control
modules. Refer to Figures 5 and 6 for proper
arrangement.
Note:
When mounting any System 350 module to rigid
conduit, attach the hub to the conduit before
securing the hub to the control enclosure.
!
WARNING:
Risk of Electrical Shock.
Disconnect power supply before
making electrical connections to
avoid possible electrical shock or
equipment damage.
Note:
For maximum electrical ratings of control, see
the
Specifications
section or the label inside
the control cover. Use adequate gauge copper
conductors only.
Consult Figures 2, 5, and 6 for proper wiring
configurations and terminal designations.
