6.9 CONNECTING THE WIRING
WARNING
Before wiring the Harmony Ball Return, all power to the unit must be locked out and
tagged out at the main breaker box or serious injury could result. Never open a control
box that has power and always be sure that the control box cover is secured before
applying power!
CAUTION
To avoid equipment malfunction or damage, the power supply must be rated for the
appropriate voltage and current.
Be sure that when any cables are inserted into their respective terminal blocks, they
make connection with the bare copper wire and not the insulated part of the wire.
1. Verify that the power to the unit and the associated pinspotters is turned OFF at the main
circuit breaker. Also, ensure that the local AC power disconnect is removed.
2. Fuses are provided with all ball lift control boxes.
Spare fuses are not provided. Install the correct
fuses for the input voltage. Check the appropriate
box on the side label to indicate which fuse this
specific control box will use.
3. Remove the cover from the ball lift control box.
