8700 W AC-Input Power Supply

Remote Power Cycling Feature

The 8700 W power supply is equipped with a remote power cycling feature that allows you to remotely
turn on or turn off the power supply through an external relay controller box.
typical remote power on/off setup. A three-position terminal block and a switch, located on the lower
right quadrant of the power supply faceplate (see

Terminal Block
The terminal block has three contacts labeled 1, 2, and 3. Two control wires from an external relay
controller box attach to either positions 1 and 2 or positions 2 and 3. Positions 1 and 2 are used when the
relay controller box contains a normally-open (NO) type of relay. Positions 2 and 3 are used when the
relay controller box contains a normally-closed (NC) type of relay.
Relay Controller Box Switch
The relay controller box switch, located next to the terminal block, allows you to match the power supply
power control signal's active state with the type of relay contained in the external relay controller box
(either a normally-open type of relay or a normally-closed type of relay).
Ferrite Bead
A plastic bag containing one ferrite bead and two 4-inch plastic ties is included with the 8700 W power
supply AC power cords. The ferrite bead is a passive device that limits high-frequency interference on
interface and control cables, and is only required when you install the remote power-cycling feature that
is supported by the 8700 Watt power supply. The ferrite bead is installed on the two control wires that
come from the relay controller box to the terminal block on the 8700 W power supply. The ferrite bead
should be installed as close as possible to the power supply terminal block for the bead to be effective.
You do not need the ferrite bead for 8700 Watt power supply installations that do not include the remote
power-cycling feature. If you need to install the ferrite bead, refer to
