Check the position of the relay controller switch located next to the terminal block.
The switch should be in the down, NO (normally open) position if the relay controller box uses a NO
relay. This the default and the recommended position. If the relay controller box uses a NC relay, the
relay controller switch should be in the up position.
You are now ready to install the ferrite bead on the control wires. Follow the installation instructions
supplied in the package containing the ferrite bead or the installation procedure in the next section.
Installing the Ferrite Bead
The ferrite bead is a passive device that limits high-frequency interference on interface and control
cables, and it is only required when you install the remote power-cycling feature that is supported only
by the 8700 Watt power supply. The ferrite bead is installed on the two control wires that link the
external relay controller box with the remote power-cycling terminal block on the 8700 W power supply.
You do not need the ferrite bead for 8700 Watt power supply installations that do not include the remote
power-cycling feature.
