Hook-Up (continued)
The VZ-7’s blue connector should be carefully
plugged into the motor’s 16-pin receptacle. Fi-
nally, re-insert the 5 pin power connector into
the motor’s socket. (Because of the power surge
to charge the motor’s capacitors, NEVER plug
in the power connector when voltage is on!)
The VZ-7’s white harness isn’t connected at this
time. Power up.
.
Note: A small number of furnace or air handler
manufacturers choose not to run a 24V hot wire
in their harnesses to the motor. This makes us-
ing the VZ-7 more difficult, because an outside
source of power must then be used. The red
wire with fuseholder is used for these type of
units. It has a special fuse to protect your VZ-7
and the motor from damage that can occur if
24V is applied out of phase with the other wires.
Never modify the connectors to try to get 24V
any other way. Your warranty will be void and
you may damage the VZ-7 and/or the motor.
Connect the alligator clip ONLY to 24 VAC ‘Hot’;
the 24 VAC ‘Common’ is always supplied
through the harness.
