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.

5.1 Electrical connection
WARNING
!
Device is energized
Incorrect wiring can result in injury or fatality
‣The electrical connection may only be established by an electrical technician.
‣The electrical technician must have read and understood these Operating Instructions and
must follow the instructions they contain.
‣Prior to beginning any wiring work, make sure voltage is not applied to any of the cables.
‣The ground connection must be made before all other connections. Any interruption in the
ground can cause danger.
NOTICE
The device does not have a power switch
‣You must provide a protected circuit breaker in the vicinity of the device.
‣This must be a switch or a power-circuit breaker and you must label it as the circuit breaker
for the device.
‣The mixed connection of safe extra-low voltage and dangerous contact voltage to the relay
is not permitted.
Before commissioning, compare the supply voltage with the information specified on the
nameplate (left-hand side of the housing).
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 OUSTF10 sensor, the lamp voltage needs to be reduced from 12V to 5V.
User has to do this change prior to connecting the sensor.
NOTICE
Changing the sensor type without using lamp voltage sense tool
Can damage the lamp
‣Use this tool before connecting any new sensor type to the transmitter.
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. Adjust the voltage trimmer to the rated lamp voltage.
4. Take off the voltage sense tool.
5. Connect the cable set of the new sensor to the lamp power supply.
6. Observe the lamp voltage on the display and fine tune the lamp voltage to compensate the
voltage drop on the cable.
