W1 – MTR PWR
The MTR PWR quick connect provides voltage to the
line side of the fan speed relays through an external
jumper. For PSC motors, this will be the line voltage
of the unit. For EC motors, this will either be 24VAC
(without PWM) or a switch contact common (with
PWM).
W2 – EARTH
EARTH connection grounds the secondary side of the
transformer to the enclosure cabinet through a wire
bonded to the control enclosure.
