Notes:
1. Operating voltage is the min and max voltage for which the unit can function. Never
operate outside of this min and max voltage.
2. The Acceptable Performance Range is the min and max voltage for which the unit
performance is designed and rated to give acceptable performance.
Route power and control wiring, separately,
through the utility entry in the unit. Do not
run power and control signal wires in the
same conduit.
All units require field supplied electrical
overcurrent and short circuit protection.
Device must not be sized larger than the
Maximum Overcurrent Protection (MOP)
shown on the unit nameplate.
Codes may require a disconnect switch be
within sight of the unit.
It is recommended that the field installed
overcurrent protection or disconnect switch
not be installed on the unit.
On units with external control box, electrical
supply can enter through either side of the
controls compartment.
