Quick Start Guide
3.2.2
Installation regulations
Local regulations or VDE 0100 (Regulations of German Electrotechnical
Engineers) must be observed.
When using 24 V supply voltage, an approved power supply with reinforced
insulation to mains is required.
3.2.3
Fuse
Use a fuse as stated in the connection diagrams.
3.2.4
Residual Current Circuit Breaker (RCCB) protection
In case of a defect, the distribution voltage must automatically be cut-off by
an RCCB protection switch to protect against indirect contact with
dangerous voltages.
3.2.5
Power supply
Power supply switch
A voltage disconnection switch must be provided near the device.
Supply voltage
Compare the supply voltage applied with the specifications given on the
electronic module and nameplate before switching on the device.
3.2.6
Wiring
Field wiring cables
The diameter has to match the clamping range of the used cable gland.
The cross-section has to match the clamping range of the connection
terminals and the maximum current must be considered.
All field wiring must have insulation suitable for at least 250 Vac.
The temperature rating must be at least 194 °F (90 °C).
Use a shielded cable when there are electrical interferences present that are
higher than stated in the EMC standards. Otherwise, an unshielded
instrumentation cable can be used.
Guiding the cables in the terminal box
The field wiring cables must be cut to a length to be able to properly fit them
into the terminal box.
Connection terminals
When preparing cable wires for connection to terminals in a standard or type
'D' housing, the wire insulation must be stripped to show no more than 0.31
