Assembling the driver (oscillator/demodulator)

Assemble either:
with assembly adapter on a hat-rail
•
with assembly adapter via screw mounting on a firm surface
•
The driver must be mounted electrically insulated on its mounting socket and inside a pro-
•
tective housing, because the driver housing is part of the instrinsically safe circuit. The dis-
tance of the driver housing to adjacent drivers, or any other conductive part of the housing,
must always be above 2 mm. The mounting socket ensures that this minimum gap is
observed.
C
The driver is category 2 equipment and must always be positioned outside zone
0. In areas exposed to explosion hazards, it may only be connected to an
intrinsically safe supply circuit (Ex ia IIC).

4.2.1 Mounting on hat-rail

1
*For mounting on a hat-rail, the mounting tabs for screw mounting can be separated at the predetermined breaking point.
1. For screw mounting, break off both tabs and attach the driver with the assembly adapter by
sliding it into place
2. Affix the assembly adapter to a hat-rail (DIN EN 60715 TH35):
Place rear part of the assembly adapter (see figure above, item A) onto the guides of the
hat-rail and press driver and adapter downwards until the adapter clicks into place

(figure ).
You need to secure the installed driver against misalignment with hat-rail end clamps. The hat-
rail end clamps are included with our recommended protective driver housings AC-2108 for up
to 3 drivers, and AC-2109 for up to 6 drivers.
