DANGER
Mortal danger from electric shock!
Improperly installed or damaged components in the electronics instal-
lation can cause injury.
ð
Ensure that all work on the electrical installation is performed by a
qualified electrician.
ð
Ensure that all work on the electrical installation is performed in a
de-energised state.
ð
Ensure that the power supply is secured with a fault current
protective circuit.
ð
Replace damaged cables or components without delay.
7.1 Principles
Make sure that the installation location complies with the following re-
quirements:
n
The display is easily accessible and is visible.
n
Plan to leave min. 20 cm free space for the installation of the cable
underneath the device. You must be able to install the cable without
kinking or damage.
n
Mount the sensors 30 cm above the ground.
n
Compliance with the permissible ambient temperatures (see section 5
“Technical data” on page 10).
7.2 Installation on the wall
Resources required:
@
Assembly kit
@
Drill
@
Slotted screwdriver
Perform the following steps:
1.
Drill the four drillholes for wall mounting. The exact dimensions are
stated in section 6 “Dimensions” on page 11.
2.
Unscrew the screw on the right-hand side of the device and pull out
the rod.
4
You can now open the device.
3.
Open the device and use the screws for wall mounting. Ensure that
the device is secured to the wall.
4.
Close the device again using the rod.
ü
The device is fitted on the wall.
7.3 Electrical installation
The voltage supply to your device can now be performed via a normal
Schuko plug or a control cabinet. Perform the specifications of this sec-
tion for devices without a pre-fitted Schuko plug.
Precondition for action:
ü
The device was installed in accordance with section 7.2 Installation
on the wall.
ü
A voltage supply with 100 - 240 V AC (50 / 60 Hz) is available.
ü
The voltage supply is deactivated before the start and secured
against reactivation.
ü
The housing is open.
Resources required:
@
Schuko plug
@
Wire end sleeves 0.75 - 2.5 mm²
1.
Fit wire end sleeve to the cable ends if the supply cable does not
have them.
2.
Open the device housing.
3.
Lead the supply cable through a cable screw connection to the un-
derside of the device.
4.
Turn the cable screw connection union nut until the line is fixed in the
screw connection so that the screw connection performs strain relief.
Ensure that the feed cable is installed loosely.
5.
Connect the voltage supply to the clamps 44 - 52. Observe the divi-
sion into protective earth (PE), neutral conductor (N) and the phase (L)
on the circuit board.

Only 3 of 9 clamps are required for connection of the voltage
supply. You can use the free clamps to supply further devices
with voltage.
The contact load rating amounts to max. 4 A.
