Before installing any connecting wiring, refer to Table
15, p. 33 for conductor sizing guidelines and;
Use copper conductors unless otherwise specified.
Ensure that the AC control voltage wiring between
the controls and the unit's termination point does
not exceed three (3) ohms/conductor for the length
of the run.
Refer to dimensional information beginning with
Figure 1, p. 14 for the electrical access locations
provided on the unit.
Do not run the AC low voltage wiring in the same
conduit with the high voltage power supply wiring.
Be sure to check all loads and conductors for grounds,
shorts, and miswiring. After correcting any
discrepancies, reset the circuit breakers by pressing the
black button located on the left side of the transformer.

Before installing the connecting wiring between the
components utilizing a DC analog output/input signal
and the unit, refer to Table 16, p. 33 for conductor
sizing guidelines and;
Use standard copper conductor thermostat wire
unless otherwise specified.
Ensure that the wiring between the controls and the
unit's termination point does not exceed two and a
half (2-1/2) ohms/conductor for the length of the
run.
NNoottee:: Resistance in excess of 21/2 ohms per
conductor can cause deviations in the
accuracy of the controls.
Refer to dimensional drawings beginning with
Figure 1, p. 14 for the electrical access locations
provided on the unit.
Do not run the electrical wires transporting DC
signals in or around conduit housing high voltage
wires.
