Connect the AC power cord supplied in the SecureSync ancillary kit to the AC input on the rear
panel and the AC power source outlet. The AC input is fuse-protected with two fuses located in the
AC power entry module (line and neutral inputs are fused). The AC power entry module also con-
tains the main power switch for the AC power applied to the equipment.

power to SecureSync).
NOTE – DC power is an option chosen at time of purchase. The rear panel DC input
port connector is only installed if the DC input option is available. Different DC
power input options are available (12 V
maximum or 24/48 V input with a voltage range of 21 to 60 V at 3 A maximum).
