2. Mount the expansion board.
Figure 21 below demonstrates LEXP mounting
locations within the different panel sizes. Notice, each LEXP is labeled A, B or C.
This labeling is based upon how the LEXPs are pre-installed when they are ordered
with the L35 Series. The letters denote the range of switch inputs that will connect
to each board. Board A interfaces inputs 25-56; Board B, 57-88; Board C, 89-120.
The LEXP ships with a mounting plate. The LEXP mounts into the L35 Series with
four screws. Mounting holes in the L35 Series are located on mounting brackets of
the interior between all relays. Use Figure 22 to locate the mounting hole positions
that match the plate size of the LEXP.
3. Connect the ribbon cable as shown.
Figure 23 shows an L3548 with 32 relays.
Two LEXP modules are shown as factory mounted. The ribbon cable connector is
keyed to ensure it is connected properly. The sockets on both the expansion board
and controller provide a slot for the key notch on the cable connectors. TRIATEK
