2.3 outputs
safety notes:
–
To avoid electrical shocks, connect power line at last.
–
For supply connections use No. 16 AWG or larger wires
rated for at least 75°C.
–
Use copper conductors only.
wArning! before connecting the output actuators
,
we recommend to configure the parameters to
suit your application (e.g.: input type, Control
strategy, alarms, etc.).

supply voltage:
100... 240 VAC (-15... +10%).
notes: 1.
Before connecting the instrument to the power
line, make sure that line voltage is equal to the
voltage shown on the identification label.
2.
The polarity of the power supply has no importance.
3.
The power supply input is NOT fuse protected.
Please, provide a T type 1A, 250 V fuse externally.
4.
When the instrument is powered by the A01 key,
the outputs are NOT supplied and the instrument
can show the
ouLd
(Out 4 Overload) indication.
