Where the product is intended for “UL” installations
removal or addition of option boards is not permitted.

!

Warning:

 

Disconnect

power before you expose
the internals of the display

If you want to open your display to install or modify option boards, follow these steps...

1) Switch off power to the display and unplug all connectors.

2) Undo all the thumb screws on the rear case, store them safely and remove the back

panel

3) Locate the main option board, which will be similar in appearance to the diagram

below. If a main option board is absent, which will be the case if the display was
ordered without any output options, then a main option board will need to be fitted.

The board assemblies will look like this:

The analog output and RS232 or RS422 plug-in option boards are fixed to the main option
board with white plastic pillars. You must apply a firm force when fitting or removing these
options.

Always be careful to connect the pins to sockets accurately. When reassembling, make
sure option boards are firmly fixed to the upper option board.
