3 Installation
3.1 Quick installation guide
If the sensor is fixed then the unit can be fitted directly to the sensor.
If the sensor is to be mounted at a right angle to the cable gland, swap the dummy plug and cable
gland.
The device can be mounted directly on the wall. A mounting bracket is available for pipe mounting
(see Fig. 4). The illuminated display can be mounted in four different positions (→ å 2):
Fig. 2: Temperature field transmitter with sensor, 4 display positions, can be plugged-in in 90° steps
Fig. 3: Turning the display
1. Remove the cover clamp (Pos. 1).
2. Unscrew the housing cover together with the O-ring (Pos. 2).
3. Remove the display with retainer (Pos. 3) from the electronics module (Pos. 4). Adjust the
display with retainer in 90°stages to your desired position and rearrange it on the particular
slot in the electronics module.
4. Then screw on the housing cover together with the O-ring. Mount the cover clamp.

4.2 Connecting the sensor
Please refer to Section 4.1 "Quick wiring guide" for the terminal assignment of the sensor
connections.
4.3 Connecting the measuring unit
Electronic parts may be damaged
► Switch off power supply before installing or connecting the device. Failure to observe this may
result in destruction of parts of the electronics.
► If the device has not been grounded as a result of the housing being installed, grounding it via
one of the ground screws is recommended.

4.4 Screening and potential equalization
Please take note when installing the device:
If screened (shielded) cables are used then the screen connected to the output (output signal 4 to
20mA) must be at the same potential as the screen at the sensor connection!
When operating in plants with high electromagnetic fields, it is recommended that all cables be
screened using a low ohm ground connection. Due to the possible danger of lightning strikes
screening is also recommended for cables that are run outside buildings!

4.5 Degree of protection
The device conforms to the requirements to IP 67 ingress protection. In order to fulfil an IP 67
degree of protection after installation or service, the following points must be taken into
consideration:
• The housing seals must be clean and undamaged before they are replaced into the sealing rebate.
If they are found to be too dry then they should be cleaned or even replaced.
• All housing screws and covers must be pulled tight.
• The cables used for connection must be of the correct specified outside diameter (e.g. M20 x 1.5,
cable diameter from 8 to 12 mm; 0.315 to 0.47 in).
• Tighten cable gland (→ å 6).
• Loop the cable before placing into the cable entry ("Water sack", → å 6). This means that any
moisture that may form cannot enter the gland. Install the device so that the cable entries are not
facing upwards.
• Cable entries not used are to be blanked off using the blanking plates provided.
• The protective olive must not be removed from the cable gland.

4.6 Connection check
After the electrical installation of the device, always perform the following final checks:
Device condition and specification Hint
Are the device or the cables undamaged (visual check)? -
Electrical connection Hint
Is the cable installation correctly separated, with no loops or crossovers? -
Are the cables load relieved? -
Have the cables been correctly connected? Compare with the
