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.

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
2
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),
5
only use a protective extra-low-voltage.
4. Carry out installation in accordance with
VDE 0100 / IEC 60364.
5. Observe the terminal assignment.
