3.2 Connect Input Power—AC or DC
Liebert SiteLink-E modules may be powered with either alternating current or direct current within
the operating range of 21.6-26.4 volts. The input power terminals are in the upper right corner of the
module (see Figure 1 for location).
1. Turn the Liebert SiteLink-E module’s power switch Off.
This prevents the module from being powered up before the wiring is completed and the proper
voltage is verified.
2. Make sure the 24VAC power source is Off.
3. Pull the screw terminal connector from the control module’s power terminals labeled 24VAC/DC
and Gnd.
4. Connect the transformer wires to the screw terminal connector (see Figure 6).
5. Apply power to the power supply.
6. Measure the voltage at the Liebert SiteLink-E’s power input terminals to verify that the voltage
is within the operating range of 21.6-26.4 VAC.
7. Insert the screw terminal connector into the Liebert SiteLink-E’s power terminals.
