6 Installation
►
Mount the unit on a DIN rail in a housing protected against dust and humidity
(min. IP54 - degree of soiling 2).
7 Electrical connection
►
Use 60/75°C copper conductors only�
7.1 Supply voltage
The external supply unit must have a safe separation� In case of a fault the
voltage can exceed the value of 60 V DC for a maximum of 200 ms, but
must not exceed the value of 120 V DC�
►
Connect supply voltage
L+
Manual reset
L+
RESET
For safety reasons the unit can only be restarted by
separation from the supply voltage in case of a fault�
It is thus recommended to install a RESET switch in
series with the L+ circuit�
After power on or a RESET the unit carries out self diagnostic functions� After this
self diagnosis the unit is ready for operation�
