Recommendation: Do not bundle or run interconnection
wiring in parallel with or in the same conduit with any
high-voltage wires (110 V or greater). Exposure of
interconnection wiring to high voltage wiring, inductive
loads, or RF transmitters may cause radio frequency
interference (RFI). In addition, improper separation may
cause electrical noise problems. Therefore, use shielded
wire (Belden 83559/83562 or equivalent) in applications
that require a high degree of noise immunity. Connect the
shield to the chassis ground and tape at the other end.
Note: Do not connect any sensor or input circuit to an
external ground connection.
MCA and MOP Calculations
Minimum circuit ampacity (MCA) and Maximum
Overcurrent Protection (MOP) calculations for units with
single-phase electric heat:
Heater amps = (heater kW x 1000)/heater voltage
Note: Use 120 V heater voltage for 115 V units. Use 240 V
heater voltage for 230 V units.
