2.1 Main Power Board
Connections to this board include the MAIN Power Input and current sensors.The
MAIN Power Input terminals are positions one through four on the four position
screw terminal block, TB1. These terminals are covered with a protective shield
for safety purposes. The current sensor assemblies interface to the TB1 positions
6 thru 10; care must be exercised to ensure that each current sensor is connected
to the correct terminals. One three terminal screw connector (RS485) is for RS-
485 communications. One two terminal screw connection (output) is for a pulse
output. One RJ-45 jack (J8) is provided for 10/100-baseT Ethernet.
