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 last 75°C.
–
Use copper conductors only.
–
SSR outputs are not isolated. A reinforced isolation must
be assured by the external solid state relays.
–
For SSR, mA and V outputs if the line length is longer than
30 m use a shielded wire.
–
Do not short-circuit the terminals of the SSR output.
WARNING! Before connecting the output actuators
,
we recommend to configure the parameters to
suit your application (e.g.: input type, Control
strategy, alarms, etc.).
