At the factory, the device is calibrated for vertical installation, but the installation
position is arbitrary. For any installation positions that are not vertical, the zero-
point signal can be corrected via the installed offset correction.
The enclosure protection type IP 65 is only guaranteed, if a suitable power sup-
ply cable is used (see accessories).
3.2 Mounting in explosive areas
• If operated in explosive areas, the valid local regulations and guidelines for
the installation and operation of electrical systems in explosive areas must
be observed.
• If units are used in potentially explosive areas, the personnel must receive
additional training or briefings or have a permit to work on explosion-protec-
ted units in potentially explosive systems.
DANGER! The operator must ensure that any falling objects cannot collide
with the installed unit.
Steps must be taken to prevent the impact creating sparks so that the protection
class of the casing is no longer guaranteed. This can be avoided by attaching
protective cover, a protective housing or similar.
