PHANTOM POWER CONNECTIONS
Some existing installations may have only 2 wires (such as coax) going to a remote room. The 480, when
used with a 792-10 Power Module, may be connected for 2-wire phantom power operation as follows:
Additional 480's may be wired in parallel at the 3-terminal block, up to a maximum of three. More than this
may cause unreliable results.
CAUTION: With any of these systems, be sure the 781 power supply is plugged into an un-switched AC
outlet. This maintains the 480 system in "standby" operation so that power-on commands can be sent to
the controlled equipment.
