ELECTRICAL CONNECTIONS
For signals connection please use shielded cables; the equipment cable
shields must be connected to a preferential ground. It’s also a good rool
avoid to pass wires near power installation cables like transformers,
inverters, motors, induction ovens etc.
HOW TO INSTALL
Z109S module is designed to be
on a DIN 46277 bar, in
installed
vertical position.
For working properly and long life, make sure that adequate ventilation is
provided for the module, avoiding placing raceways or other objects which
could obstruct the abat-vents. Avoid to install module over equipment that
generates heat.
We suggest you to install the module in the lower part of the cabinet.
HEAVY WORKING CONDITIONS:
Heavy working conditions are:
High power voltage a (> 30V / > 26 V ).
Input sensor feeded.
Use of output in impressed current.
When modules are installed side by side it may
be necessary
to
separate them at least 5 mm
in the following cases:
Upper board temperature higher than 45°C and at least one of the
heavy working conditions verified.
Upper board temperature higher than 35°C and at least two of the
heavy working temperature verified.

ACTIVE OUTPUT
: use this connection when output loop is to be
directly feeded from Z109S module.
Loop power supply given by Z109S module is protected against short
circuit.
Max load resistance 600 ohm.
PASSIVE OUTPUT
: use this connection if current loop's power supply
is given from external.
