Mounting and Wiring
Location
Ensure that the location meets the operating environment requirements and clearance requirements described in the
following sections. The controller must be installed indoors. Trane recommends locating the controller:
•
Near the controlled equipment to reduce wiring
•
Where service personnel have easy access
•
Where public access is restricted to minimize the possibility of tampering or vandalism
Mounting Instructions
To mount the enclosure:
1. Use the enclosure as a template and mark the location of the four mounting holes on the mounting surface.
2. Set aside the enclosure and drill holes for the screws at the marked locations.
Note: Drill holes for #10 (5 mm) screws or #10 wall anchors. Use wall anchors if the mounting surface is dry wall or
masonry.
3. Secure the enclosure to the mounting surface with the enclosed #10 (5 mm) screws or #10 wall anchors.
Wiring High-voltage AC Power
WARNING
Hazardous Voltage!
Disconnect all electrical power, including remote disconnects, before servicing. Follow proper lockout/tagout
procedures to ensure the power cannot be inadvertently energized. Failure to disconnect power before servicing could
result in death or serious injury.
CAUTION
Use Copper Conductors Only!
Unit terminals are designed to accept copper conductors only. Other conductors could cause equipment damage.
Important: Ensure that the correct controller model is used for 120 Vac or 230 Vac. (Refer to
To ensure proper operation of the controller, install the power supply circuit in accordance with the following guidelines:
•
The controller must receive power from a dedicated power circuit. Failure to comply could cause controller
malfunctions.
•
For CE-compliant installations, a disconnect switch for the dedicated power circuit must be near the controller, within
easy reach of the operator, and marked as the disconnecting device for the controller.
•
High-voltage power-wire conduits or wire bundles must not contain input/output wires. Failure to comply could cause
the controller to malfunction due to electrical noise.
•
High-voltage power wiring must comply with the National Electrical Code™ (NEC) and applicable local electrical
codes.
•
High-voltage wiring requires three-wire 120/230 Vac service (line, neutral, ground).
Note: The transformer voltage utilization range is 98–132 Vac (120 Vac nominal) or 196–264 Vac (230 Vac nominal).
The panel automatically detects whether the current is 50 or 60 cycle.
