4 ELECTRIC CONNECTION
4.1 Connectors
The following drawing shows the connectors of the devices.
4.2 Meaning of connectors
The following tables show the meaning of the various device connectors.
For additional information, please read chapter 8 "TECHNICAL DATA",
POWER
Device power supply (24 VAC/DC not insulated)
If the device runs on direct current, it shall be necessary to pay attention to the polarity of the supply voltage.
If the device is connected to a network of devices, it shall be necessary to:
- check that the power supply of the devices included in the network are galvanically isolated.
- the phase powering the device is the same as that of all the devices included in the network.
PART MEANING
AC/+
device power supply:
- if the device is run by alternating current, connect the phase
- if the device is run by direct current, connect the positive pole
AC/-
device power supply:
- if the device is run by alternating current, connect the neuter
- if the device is run by direct current, connect the negative pole
ANALOG INPUTS
Analog inputs
Please see paragraph 6 "CONFIGURATION" for the settings of the analog inputs.
