10. ELECTRICAL INSTALLATION
DANGER
Supply voltage!
There is the risk of an electric shock involving injury or
death when coming into contact with non-insulated
components carrying supply voltage.
measures:
During electric installations, all regulations in force
need to be adhered to (e.g. VDE 0100 / IEC 6064).
Service measures must only be undertaken when
the system is deactivated.
The removed control unit has no IP degree of
protection.
All types of electrical works must be carried out by
authorized and qualified personnel only.

NOTE
Power supply connection:
Read the permissible supply voltage on the type
plate and make sure this voltage is observed.
For the supply voltage, a reliably accessible
separator must be provided close-by (e.g. power
plug or switch), which separates all current-
carrying conductors.
At a low voltage supply (< 0 VAC / < 7 VDC), only
use a protective extra- low-voltage (SELV).
Carry out installation in accordance with VDE 0100
/ IEC 6064.
Observe the terminal assignment.
Do not install when the device is energized.
Unscrew the screws (1) and remove the upper part
of the cover (2).
Unscrew the threaded cable connection (),
remove the plug (if there is one), and lead the
cable (4) for the power supply through.
Connect the cable (4) with terminals X1 (1.1, 1.2)
().
Install the cables as shown (see also terminal
assignment in the following text).
Tighten the threaded cable connection () with a
slightly sealing effect.
Put on the upper part of the cover (2) and tighten
the screws (1) fingertight.

Connection of the potential-free contact and of the
external test:
Selection of the suitable cable.
Connection to X2 and X, as shown on the left.
The installation steps are the same as for the power
supply connection.
If the potential-free contact carries voltage that is
dangerous in the case of contact, a corresponding
separator must also be provided, as described above.

When using the potential-free contacts and the
connection external test, sufficient clearance to
the other parts of the unit, or suitable insulation in
accordance with EN 60664-1 must be ensured.
When using a multiwire, common line for the
connection of the potential-free contact and the
external test, this line must be suitable for the highest
occurring voltage and the intended temperature
range with regard to its nominal ratings.
