General installation instructions of elbow-type plug:
To mount the connection cable(2-, 3-, or 4-wire depending on type of device) the angle plug screw has to be loosened
and the coupling insert has to be removed by means of a screw driver at the position indicated (arrow).
Pull out connection cable through PG glanding and connect to the loose coupling insert as described in the wiring dia-
gram. Replace loose coupling insert onto the pins at the transmitter housing and turn cover cap with PG glanding in the
direction desired till it snaps on (4 different starting positions at 90° intervals). Re-tighten the screw at the angle plug.

Safety instructions:
This device has been designed and tested in accordance with the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and special
safety advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any other
climatic conditions than those stated under "Specification". If the device is transported from a cold to a warm environ-
ment condensation may cause in a failure of the function. In such a case make sure the device temperature has adju-
sted to the ambient temperature before trying a new start-up.
2. General instructions and safety regulations for electric, light and heavy current plants, including domestic safety regu-
lations (e.g. VDE), have to be observed.
3. If device is to be connected to other devices (e.g. via PC) the circuitry has to be designed most carefully. Internal con-
nection in third party devices (e.g. connection GND and earth) may result in not-permissible voltages impairing or de-
stroying the device or another device connected.
4. If there is a risk whatsoever involved in running it, the device has to be switched off immediately and to be marked
accordinglyto avoid re-starting.
Operator safety may be a risk if:
- there is visible damageto the device
- the device is not working as specified
- the device has been stored under unsuitable conditions for a longer time
In case of doubt, please return deviceto manufacturer for repair or maintenance.
