AC Power Supply
The power supply should be supplied by a dedicated electrical power source rated for a minimum 10A load and
have a dedicated circuit breaker.
Do not
use a switch controlled breaker or a switched electrical point to supply
electrical power. Connect the primary of a 16 to 16.5 VAC, 50-60Hz, 40VA or greater transformer to the
electrical circuit and run the secondary to the AC input on the power supply terminals.

Specific regional regulations may allow the transformer to be mounted inside the cabinet enclosure. In this case
wire the electrical circuit to the electrical termination point inside the cabinet enclosure and the secondary wires
of the transformer to the AC input on the power supply. The earth wire shall be routed to the V- terminal on the
power supply when using an internal transformer.
Warning:
⦁
This installation should be made by qualified service personnel and should conform to all local codes.
