1. GENERAL RECOMMENDATIONS

Please read before using this manual any further.
•
This manual is an integral part of the product and must be kept close to the
device for quick and easy consultation.
•
The regulator must not be used for purposes other than those described below,
and it especially cannot be used as a safety device.
•
Check application limits before proceeding.

Dixell S.r.l. reserves the right to change the composition of its products, even
without notice, ensuring the same and unchanged functionality.
1.1 SAFETY PRECAUTIONS
•
Symbol warns the user about the presence of non-insulated "dangerous
voltage" inside the product area, which may cause electric shock.
•
Symbol warns the user about the presence of important operating and
maintenance (assistance) instructions found in the documentation attached to the

of application before using the device.
•
Verify that the power supply voltage is correct before connecting the device. Do not
expose it to water or humidity. Use the controller only within the operating limits,
avoiding sudden temperature changes and high atmospheric humidity, which may
result in the formation of condensate.
•
Warning: disconnect all the electric connections before performing maintenance.
Insert the probe where it cannot be reached by the End User. The device must not be
opened. Consider the maximum current that can be applied to each relay.
•
Make sure that the wires for the probes, the loads and the electrical power supply are
separated and sufficiently distant from each other, without crossing or intertwining
with each other. In the case of applications in industrial environments, it may be
useful to use the main filters in parallel with the inductive loads.
•
The customer shall bear full responsibility and risk for product configuration in order to
achieve the results pertaining to installation and/or final equipment/system. Upon the
customer's request and following a specific agreement, Dixell S.r.l. may be present
during the start-up of the final machine/application, as a consultant, however, under
no circumstances can the company be held responsible for the correct operation of
the final equipment/system.
•

temperatures can damage it (electronic circuits and/or plastic components
forming part of the casing). Comply with the temperature and humidity limits
specified in the manual in order to store the product correctly.
o
Under no circumstances is the device to be opened - the user does not require
the internal components. Please contact qualified service personnel for any
assistance.
