5.3 Electrical connection

5.3.1 Notes on installation

The supply must comply with overvoltage category II.
■
Protect the voltage supply with a slow fuse of max. 0.5 A.
■
For the panel-mounting version, a suitable isolation device must be provided.
■
Route the signal input lines and signal output lines separately.
■
Route outward and return lines side-by-side.
■
Galvanically isolated potentials must be connected to a suitable point (e.g. earth or
■
plant ground).
For high-accuracy requirements and small measuring signals, the sensor wires
■
must be shielded and twisted. The shield should be connected at one end only to a
suitable equipotential bonding (e.g. measurement ground).
Avoid electrostatic discharges in the area of the terminals.
