Introduction

This bulletin explains how to install the Powerlink power supply, which is used to provide voltage for operating ECB remotely operated circuit breakers, Powerlink controllers, and Powerlink control busses.

The power supply is installed in a NF panelboard by connecting the power supply, which mounts like a standard circuit breaker, to the interior bus. There are two different types of power supplies. The first is intended for direct panel connection. Primary power is supplied by connecting it to the panelboard interior mounting rail and securing the white neutral wire to the panelboard neutral. The second type is intended for connection to a remote AC power source. Both are available in three different voltage ratings (see Table 1). Powerlink supplies can also be installed in Powerlink remote mount controllers. Refer to 80043–870–01 for more information.*

Two LEDs are located on the power supply labeled CL1 and CL2. The CL1 LED represents Class 1 power supplied to the control busses, while the CL2 LED represents Class 2 power supplied to the controller and any devices connected to the controller.
