Mounting dimensions:
• Installation depth: approx. 216 mm (8.51") (incl. terminals)
• Panel cutout: 138+1 x 138+1 mm (5.43+0.04 x 5.43+0.04")
• Panel thickness: 2 to 40 mm (0.08 to 1.58")
• Max. viewing angle range: from the central display axis 50° in all directions
• Securing according to DIN 43 834
!Note!
Make sure to leave an additional clearance of min. 35 mm (1.4") for cable connection.
1. Push the unit through the panel cutout from the front. To avoid heat accumulation, we
recommend keeping a distance of > 15 mm (>0.59 inch) from the walls and other units.
2. Hold the unit horizontally and then hang the two jack screws in the openings opposite (either on
left or right housing side, or at top or bottom).
3. Tighten the screws on the jack screws equally with a screwdriver such that a secure seal to the
control panel is guaranteed.
Note the following points for installation:
• A distance of min. 7 mm (0.28") has to be observed if aligning the devices in the Y direction (vertically
above on another).
• The devices can be arranged horizontally beside on another in the X direction without any spacing
between the devices.
• The grid dimension of the panel cutouts for multiple devices must be min. 196.2 mm (7.72")
horizontally and min. 156.2 mm (6.15") vertically (tolerance not considered).

4.1 Electrical connection
#Warning!
• The electrical connection must only be carried out by a certified electrician.
• Technical personnel must have read and understood the instructions in this manual and must adhere
to them.
• Ensure that there is no voltage at the power cable before beginning the connection work.
"Caution!
• The ground connection must be made before all other connections. Any interruption in the ground
can cause danger.
• Before commissioning, compare the supply voltage with the information specified on the nameplate
(left-hand side of the housing).
• The mixed connection of safe extra-low voltage and dangerous contact voltage to the relay is not
permitted.
• Provide a suitable switch or circuit breaker when installing in a building. This switch must be installed
near the unit (easily accessible) and must be properly labeled.
• An overcurrent protective unit (nominal current ≤10 A) is required for the power cable.

Lamp voltage adjustment (Vx Adj.):
• Turn clockwise to decrease voltage.
• Turn counter-clockwise to increase voltage.
Lamp voltage sense tool:
The lamp voltage sense tool allows to read the lamp voltage on the display of CVM40 without the cable
and sensor connected.
This procedure is only necessary when changing the sensor type. E.g. when changing from an OUSAF44
sensor to an OUSAF11 sensor, the lamp voltage needs to be reduced from 12V to 5V. User has to do
this change prior to connecting the sensor. Refer to the sensor manual for the lamp voltage of the
respective sensor.
"Caution!
Use this tool before connecting any new sensor type to the transmitter.
Failure in doing so can damage the lamp.
By using the lamp voltage sense tool the lamp voltage can be adjusted approximately to the rated value
before connecting the sensor. Connect the power supply pin V1.1 and V1.2 to voltage sense pin V1.3
and V1.4.
The following steps are required for changing the sensor type:
1. Disconnect the cable set of the old sensor.
2. Connect the lamp voltage sense tool to the lamp power supply.
3. Select in the main menu of CVM40 "Diagnosis/simulation" and then "Sensor status".
4. Adjust the voltage trimmer to the rated lamp voltage by using a small screwdriver.
5. Take off the voltage sense tool.
6. Connect the cable set of the new sensor to the lamp power supply.
7. Observe the lamp voltage on the display and fine tune the lamp voltage to compensate the voltage
drop on the cable.

4.3 Terminal assignment
"Caution!
If high-energy transients occur when using long signal cables, we recommend connecting a suitable
overvoltage protection (e.g. E+H HAW560/562).
Use shielded signal lines for serial interfaces!
4.3.1 Cable specification, spring terminals
All connections on the rear of the unit are designed as screw or spring terminal blocks with reverse
polarity protection. This makes the connection very quick and easy. The spring terminals are actuated
with a slotted screwdriver (size 0).
!Note!
No ferrules need to be used when connecting flexible wires to spring terminals.
