Power Connection

Depending on the equipment configuration at time of purchase, SecureSync can be powered from
an AC input, a DC input or with both AC and DC input (DC input is an option). Supplying both AC
and DC input power provides redundant and automatic power switchover in case one or the other
input power sources is lost.
Before connecting power to the unit, be sure that you have read all safety information detailed in
section "SAFETY" on page 18.
2.7.1

Input Power Selection

As long as the AC input power is present, and SecureSync is equipped with the DC redundancy
option, it will utilize the AC power source over DC power.
