1. Important warnings for safety
This chapter contains important information for the safety. The not observance of these
instructions may result in serious personal injury or death and can cause serious damages to the
Thyristor unit and to the components system included.
The installation should be performed by qualified persons.
In the manual are used symbols to give more evidence at the notes of safety and operativity for
the attention for the user:
may result in serious personal injury or death by Electrical Shock Hazard Symbol

A “NOTE” marks a short message to alert you to an important detail.
A “CAUTION” safety alert appears with information that is important for protecting your
equipment and
performance. Be especially careful to read and follow all cautions that apply to your application.
A “WARNING” safety alert appears with information that is important for protecting you, others
and equipment
from damage. Pay very close attention to all warnings that apply to your application.
1.1. Safety notes
WARNING! To avoid damage to property and equipment, injury and loss of life, adhere to applicable
electrical codes and standard wiring practices when installing and operating this product. Failure to do
so could result in damage, injury and death.
WARNING! All service including inspection, installation, wiring, maintenance, troubleshooting, fuse
or other user serviceable component replacement must be performed only by properly qualified
personnel. Service personnel must read this manual before proceeding with work. While service is
being performed unqualified personnel should not work on the unit or be allowed in the immediate
vicinity.
WARNING! When in use the power controller is connected to dangerous voltages. Do not remove the
protective covers without first disconnecting and preventing power from being restored while servicing
the unit.
WARNING! Do not use in aerospace or nuclear applications.
4 User Manual
PMA-Relay S 3PH from 60A to 210A
WARNING! The power controller’s protection rating is IP20 with all covers installed and closed. It must
be installed in an enclosure that provides all the necessary additional protections appropriate for the
environment and application.
WARNING! Ground the power controller via the provided protective earth grounding terminal. Verify
ground is within impedance specifications. This should be verified periodically.
WARNING! Electric Shock Hazard: when the power controller has been energized, after shutting off the
power, wait at least one minute for internal capacitors to discharge before commencing work that brings
you in to contact with power connections or internal components.
WARNING! The installation must be protected by electromagnetic circuit breakers or by fuses. The
semiconductor fuses located inside the power controller are classified for UL as supplementary
protection for semiconductor devices. They are not approved for branch circuit protection.
WARNING! When making live voltage or current measurements, use proper personal protective
equipment for the voltages and arc-flash potentials involved.
WARNING! Verify the voltage and current ratings of the power controller are correct for the application.
CAUTION: To avoid compromising the insulation, do not bend wire or other components beyond their
bend radius specifications.
CAUTION: Protect the power controller from high temperature, humidity and vibrations.
CAUTION: The power controller warranty is void if the tested and approved fuses are not used.
CAUTION: Only trained and authorized personnel should access and handle the internal electronics and
they must follow proper electro-static prevention procedures.
CAUTION: Install an appropriately sized RC filter across contactor coils, relays and other inductive
loads.
CAUTION: The thyristor units here described have been designed for use with sinusoidal networks with
nominal frequency 50-60 Hz. Any application with NON-SINUSOIDAL, distorted or disturbed networks
could compromise the correct operation of the unit.
NOTE: Provide a local disconnect to isolate the power controller for servicing.
NOTE: The nominal current is specified for ambient temperatures at or below 40° C. Ensure the application
design allows for adequate cooling of each power controller. The power controller must be mounted
vertically. The cooling design must prevent air heated by one power controller from causing power
controllers mounted above to exceed the ambient operating temperature limit. When power controllers
are mounted side by side allow a minimum spacing of 15mm between them.
NOTE: Use only copper cables and wires rated for use at 75°C or greater.

2. Maintenance
In order to have a corrected cooling, the user must clean the heat-sink and the protective grill of
the fans.
The frequency of this servicing depends on environmental pollution.
Also check periodically if the screw for the power cables and safety earth are tightened correctly
