Control Panel Terminals
The Termination and PSU PCB (also known as the backplane) is located at the rear of the main control
panel back box.
The Loop cards may be plugged into the loop card slots on the backplane. To avoid damage, ensure that
the panel is powered down whilst connecting and removing the loop cards. When connecting, do not
press down on the loop card other than where indicated. Similarly, when removing, do not pull the centre of
the card but pull from both ends at the same time so that the PCB does not get flexed.
