Verifying model number for local power requirements
Table 12 lists the available BMTX BCU model. You can find the model
number on the shipping label or on the product label inside the enclosure.
To ensure proper operation of the BMTX BCU, install the power supply
circuit in accordance with the following guidelines:
• The BCU must receive power from a dedicated power circuit. Failure
to comply may cause control malfunctions.
• A disconnect switch for the dedicated power circuit must be near the
controller, within easy reach of the operator, and marked as the dis
-
connecting device for the controller.
• High-voltage power-wire conduits or wire bundles must not contain
input/output wires. Failure to comply may cause the controller to mal
-
function 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).
To connect high-voltage power wires:
ƽWARNING
Hazardous voltage!
Before making electrical connections, lock open the supply-power dis-
connect switch. Failure to do so may cause death or serious injury.
