Making The AC Power Connection
You must employ a dedicated 117VAC 15 AMP circuit, with a third-wire ground, supplied to a
standard electrical outlet (NEMA 5-15R) for the AC power connection.
•
For added equipment protection, connect a plug-in power line surge protector between the
power cord and the AC outlet.
•
Thoroughly check out the installation before connecting the power cord to an electrical
outlet to apply AC power to the system.

Identifying The Fuses
The system is protected against short circuit damage by a fuse located on the right side of the
common equipment cabinet. Always replace the fuse with one of the same value and type;
otherwise, equipment damage could result.
