Please observe the followings:
Dangerous voltages
A power pack without safe isolation may lead to
dangerous voltages in the case of a fault. This may
damage the system and cause injuries arising from
electric shock.
Only use a power pack with safe isolation
O
according to EN 60747, classification VDE 0551!
This ensures that the electric circuits comply with
SELV/PELV electric circuits in accordance with
IEC 60364-4-41.
Total current is too high
The currents from the sensor and valve line (each
max. 3 A) are summed up. If the total output of the
0 volt line is greater than 4 A, the device's plug and
conductors will be overloaded.
Design the DDL system so that the total output of
O
the 0 volt line is less than 4 A.
