Protege 16 PGM Output Expander
Installation Manual | June 2017
2.5
AC Power
The Protege PGM Expander should be supplied by a dedicated electrical power source rated for a minimum
10Amp 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 16.5VAC, 50/60Hz, 40VA Transformer to
the electrical circuit and run the secondary to the AC input on the controller terminals.

Specific regional regulations may allow the transformer to be mounted inside the enclosure. In this case wire the
electrical circuit to the electrical termination point inside the enclosure and the secondary wires of the
transformer to the AC Input on the controller.
i
Termination of wiring to the PGM Expander while power is applied or the battery is connected may
cause serious damage to the PGM Expander and will VOID ALL WARRANTIES OR GUARANTEES.
Power the PGM Expander ONLY after all wiring, configuration and jumper settings are completed and
verified.

Backup Battery
It is recommended that a minimum of a 4Ah battery is used as the main backup battery. From the accessory
bag provided, connect the RED and BLACK battery termination wires to the B+ and B- terminals. Connect the
spade terminals to the battery as shown below. Connection of the battery in reverse will not damage the PGM
Expander but will cause the battery fuse (5A Fast Blow) to blow and require replacement.
