Wiring high-voltage ac power
This chapter shows how to wire high-voltage ac power to the enclosure.

Local power requirements

The Tracer MP581 controller is available in five configurations, described
in Table 3. Before wiring high-voltage power, make sure that you have the
correct model for local power requirements. You can find the model num-
ber on the shipping label or on the product label inside the enclosure.
Table 3. Tracer MP581 models
Model Number
BMTM000AA0A0 Enclosure, 120 Vac
BMTM000AA0A1 Enclosure, 120 Vac, with operator display
BMTM000BA0A0 Enclosure, 230 Vac, CE-compliant
BMTM000BA0A1 Enclosure, 230 Vac, with operator display, CE-compliant
BMTM000CA0A0 Frame-mounted, 24 Vac, CE-compliant

Circuit requirements

To ensure proper operation of the Tracer MP581, install the power supply
circuit in accordance with the following guidelines:
The Tracer MP581 must receive high-voltage 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 power wiring requires three-wire 120/230 Vac service.
Use copper conductors only.
Note:
The voltage utilization range for the Tracer MP581 transformer
is 98–132 Vac (120 Vac nominal) or 196–264 Vac (230 Vac nomi-
nal). The panel detects whether the current is 50 or 60 cycle.
