The wiring is defined in the circuit diagram of the PNOZmulti Configura-
tor.
Please note:
` Information given in the "Technical details" must be followed.
` Use copper wire that can withstand 75 °C.
Verdrahtung_multi_Analogeingangsmodul ` The power supply that feeds the expansion module and the input de-
vices must meet the regulations for extra low voltages with safe sep-
aration (SELV, PELV).
` 6 connection terminals are available for each of the supply connec-
tions 24 V and 0 V. This means that the supply voltage can be looped
through several connections and the encoder can be supplied.
` Use shielded, twisted pair cable for the connections on the input cur-
rent circuits.
` Separate the supply voltage cable from the analogue input current
lines.
` If the analogue input module is used to measure current, the voltage
inputs must be short-circuited.
` For transducers located outside the control cabinet: Where the
cable enters the control cabinet, the cable shield must be connected
to the earth potential over a wide surface area and with low imped-
ance (connect in star).
NOTICE
If the analogue input module is used to measure voltage, both
inputs must be wired.
