Electric connection
3.4.1
Electric connection
WARNING
For the electrical installation, observe VDE 0100 or an equivalent international standard for
setting up high-voltage systems having nominal voltages under 1000 V.
Failure to comply with these regulations can result in death, personal injury and/or damage
to property.
3.4.2
Mains connection
● The device comes with an appliance plug which may only be connected to the mains
supply line by qualified personnel. The mains supply line must comply with the valid
regulations and conditions for the place of installation and be provided with a protective
conductor which lies at the potential of the enclosure. The cross-section of each wire
must be ≥ 1 mm². Connect the phase conductor to the marked position in the plug.
● Install the mains line separately from the signal lines.
● Provide a mains disconnection device in the direct vicinity of the device (for load rating,
see rating plate). It must be readily accessible and marked.
● Check whether the existing mains voltage agrees with the mains voltage specified on the
rating plate.
3.4.3
Connection of the signal lines
WARNING
Only connect the signal lines to devices which have reliable electric isolation from their
power supply.
● Connect the signal lines to the SUB-D plug connectors on the rear of the device.
● As a measure to suppress sparking across the relay contacts (e.g. limit relays), RC
elements must be connected as shown in the following figure. Note that the RC element
results in a drop-out delay for an inductive component (e.g. solenoid valve).
