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 60364).
•
When the control unit is open, service and installation works 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 authorised and qualified personnel only.
Note:
Power supply connection:
1.
Read the permissible supply voltage on the type
plate and make sure this voltage is observed.
2. 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.
3. At a low-voltage supply (< 50 VAC / < 75 VDC),
only use a protective extra-low-voltage.
4. Carry out installation in accordance with
VDE 0100 / IEC 60364.
5. Observe the terminal assignment.
6. Do not install when the device is energised.
7. Unscrew the screws (1) and remove the upper
part of the cover (2).
8. Unscrew the threaded cable connection (3),
remove the plug (if there is one), and lead the
cable (4) for the power supply through.
9. Connect the cable (4) with terminals X1 (1.1, 1.2)
(5).
10. Install the cables as shown (see also terminal
assignment in the following text).
11. Tighten the threaded cable connection (3)
with a slightly sealing effect.
12. Put on the upper part of the cover (2)
and tighten the screws (1) fingertight.
