WIRING
4.1.
Wiring conditions
–
The transmitter is SELV supplied. In the case of DC supply the connection is independent of
polarity.
–
Only SELV circuits can be switched on to the relay or the solid state output.
–
The house must be grounded to have noise protection; it should be grounded to the
equipotential bonding net.
–
3-wire DC powered devices can be created by connecting one of the power supply wires to
the white wire of the current output (GND).
–
The units and the cables should be arranged so that the fastening outside the device
relieves the end of the cable of any traction.
4.2.
Connection cable extension
–
The shielding should be connected to the shielding of the extension cable and it should be
grounded at the processing unit.
