2.2.6 Logic Inputs
Safety notes:
– Do not run logic input wiring together with power cables;
– The instrument needs 150 ms to recognize a contact
status variation;
– Logic inputs are NOT isolated by the measuring input.
A double or reinforced isolation between logic inputs and
power line must be assured by the external elements.

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 con" gure the parameters to
