Electric and magnetic fields. In order to avoid the harmful influence of certain power
equipment, keep the device away from power contactors, static relays with triacs and
thyristors, motors, and switchgear.
Wiring. Precautions must be taken with the connections, in particular those of the
measurement input and the analogue output. These links are sensitive to interference:
use twisted and screened cables, with the screening insulated and connected to the
earthing terminal of the device. Keep these links separate (different cable runs) from
power lines (mains and control circuit) over their entire length.
The same precautions must be taken for On/Off links, such as the logical control output
(to command a static relay) and the alarm output.
On the links of On/Off outputs for AC or DC control of contactors, solenoid valves, and
two-way motors, whether they are outputs of controllers, threshold relays, or supervision
boards, we recommend placing RC circuits on the terminals of the inductive loads (coils
of contactors and solenoid valves, motors, etc.) controlled by the outputs of the devices,
and placing a reverse diode on the terminals of an inductive load supplied with DC.
Mains connection. In the case of a disturbed network (in particular if the installation
includes static relays operating by variation of the phase angle), supply the devices via
an isolation transformer with earthed screen.
If the mains may be unstable, check that the voltage supplied remains within the
tolerances of the device. If necessary, use a voltage stabiliser. In the presence of
networks with a high level of interference, use suitable mains filters.
Do not use the mains terminals of the device to power the controls (contactors, relays,
etc.)
In a general way, the rules and standards for electrical installations must be observed
and the earth terminals must be wye-connected to earth or connected to a protective
conductor (equipotential link) having a cross section at least equal to the cross section of
the supply wires. The boxes or cabinets must have disconnecting devices (contactors,
differential devices, fuses, etc.) and the instruments must be supplied from the most
direct sectioning device.

2.2. Installation

Remove all burrs from the cut-out before installing. Make sure that no pieces of metal
get into the device through the ventilation slits. Remove the two attachment yokes
screwed to the back of the device. Insert the controller through the front of the panel and
put the attachment yokes back in place.
