Figure 35 – Basic Example of Input Boards Installed in a Separate Panel
This diagram shows the Input Boards installed in the second (auxiliary) panel. The CPU, DSI are in the Main Panel.
2. You must decide how the boards will be installed in the electrical cabinets.
a.
SINGLE LAYER INSTALL:
Relay boards are mounted onto existing standoffs – be sure you have enough clearance
when the door is closed for the wiring to the Relays
.
YOU CANNOT MOUNT THE BOARD FLUSH TO THE CABINET
WALL – YOU MUST USE A SPACER (STANDOFF).
(SEE PART 4.6.3 FOR EXACT INSTRUCTIONS)
b.
DOUBLE LAYER (STACKER KIT):
Relay boards are mounted using the Stacker Kit that provides 12 Lock Washers
spacers (standoffs) – be sure you have enough clearance between boards and when the door is closed for the
wiring to the Relays. One kit of 12 spacers mounts 2 Relay Boards in a stacked configuration.
YOU CANNOT
MOUNT THE BOARD FLUSH TO THE CABINET WALL – YOU MUST USE A SPACER (STANDOFF).
Figure 36 – Example of Single Layer vs. Stacked Install (SEE PART 4.6.3 FOR EXACT INSTRUCTIONS)
Diagram shows board’s component-side up. The boards are install flat and component-side-up, which uses 4 studs (or 2 slots).
Installer will wire the Power Input to a separate 2
nd
power supply (i.e. not the P.S. used by the CPU/DSI ).
