How  to  install  option  boards

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

!

Warning:

 

Disconnect

power  before  you  expose
the  rear  of  the  meter

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

1)

Switch off power to the meter and unplug all connectors.

2)

Unclip the front bezel. This is easier if you squeeze the top and bottom of
the case, near the front.

3)

Remove the small screws shown in the diagram.  If the meter doesn’t yet
have an output option  board, the top screw may not yet be fitted.

4)

Slide the electronic boards out throught the front  of the case. You can easily
separate the upper option  board from the
main board. We strongly suggest that you
use anti-static precautions to prevent
damage to the  semiconductors.

The board assemblies will look something like this...

The analogue output and RS232 or RS422 plug-in option boards are fixed to the upper 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. When the boards are replaced in the
case, secure them again with the two small black screws.
