Preparing to Install or Remove Options Modules
CAUTION:
Before removing the instrument from it’s housing, ensure that all power has been
removed from the rear terminals. Modules / boards should only be replaced by a
trained technician.
1. Remove the instrument from its housing by gripping the edges of the front panel (there is a
finger grip on each edge) and pull the instrument forwards. This will release the instrument
from the rear connectors in the housing and will give access to the boards.
2. Take note of the orientation of the instrument for subsequent replacement into the
housing. The positions of the boards in the instrument are shown above.
