Connect the Power
You can use the following procedure to connect power to the RocketLinx ES7528. The RocketLinx ES7528 is equipped with
both AC and/or DC1/DC2 power inputs.
The RocketLinx ES7528 provides redundant or aggregated power inputs (AC and/or
DC1/2). DC1 and DC2 inputs support reverse polarity protection. The RocketLinx
ES7528 will signal an alarm for loss of power on either DC1 or DC2.
1.
Connect the power cord to the AC power input connector.
Note: To reach the maximum total power budget, power inputs must be
aggregated. Refer to the following table for detailed information.
2.
Connect the DC power inputs.
Note: Power should be disconnected from the power supply before connecting it
to the switch. Otherwise, your screwdriver blade can inadvertently short
your terminal connections to the grounded enclosure.
a.
Insert positive and negative wires into V+ and V- contacts.
b.
Tighten the wire-clamp screws to prevent the wires from coming loose.
This table provides power supply specifications for the RocketLinx ES7528.
