Thanks for choosing this PEGO electrical panel.
This manual gives detailed information on installation, use and maintenance of ECP300
EXPERT series electrical panels and special version. Our products are designed and built
in compliance with current standards, on the specific field of refrigeration and conditioning
systems. A different use is allowed respecting the working conditions for which the panel is
designed and made.
Before using the panel it’s suggested to fully read this manual paying special attention to
the highlighted parts with the simbology descripted below:
This symbol is used to focus on notes concerning installation, use and
maintenance operations
This symbol is used to focus on important notes
This symbol is used to indicate the prohibition to do the shown
operation
Instructions for disposal:
The electric board is made up of metal parts and plastic parts. In reference to European
Union directive 2012/19/EC issued on 4 July 2012 and the related national legislation,
please note that:
A. WEEE cannot be disposed of as municipal waste and such waste must be collected
and disposed of separately.
B. The public or private waste collection systems defined by local legislation must be
used. In addition, the equipment can be returned to the distributor at the end of its
working life when buying new equipment.
C. The equipment may contain hazardous substances: the improper use or incorrect
disposal of such may have negative effects on human health and on the
environment.

STANDARD EQUIPMENT FOR ASSEMBLY AND USE
The ECP300 EXPERT electrical panel, for assembly and use, is equipped with:
•Nr 4 sealing gaskets, to be placed between the fixing screw and the back of the box.
• Nr 1 use and maintenance manual.
• Nr 1 wiring diagram.
• Nr 1 drilling layout.
• Nr 2 NTC probes 10K 1% .
MECHANICAL ASSEMBLY OF THE PANEL
❑Each panel is designed for wall mounting; choose an appropriate fixing
system, depending on the weight of the panel and the type of support on
which it will be fixed.
❑Install the panel in places that respect its IP rating.
❑Keep the IP protection level of the appliance intact by properly assembling
the cable glands and/or the pipe clamps with appropriate characteristics.
❑Install the panel at a height that allows the operator an easy use and internal
access. The operator should not come to be in a dangerous situation when
he is working on the panel. The height must however be between 0.6 and 1.7
meters from the floor.
❑Install the electrical panel in an area away from sources of heat and possibly
protected from atmospheric agents.
Following are the steps to perform a correct mechanical installation of the panel.

ELECTRICAL WIRINGS
❑For electrical connections, refer to the specific wiring diagram and to the
technical characteristics of the panel model to be installed.
❑The power supply to the panel must be carried out exclusively with a
dedicated line, upstream of which a device suitable for protection against
indirect contacts (differential switch) must be installed.
❑Avoid putting power cables and signal cables (probes and digital inputs)
in the same conduits (or pipes).
❑Avoid using multipolar cables in which there are conductors connected to
inductive and power loads and signal conductors such as probes and
digital inputs.
❑Reduce the lengths of the connecting cables as much as possible,
preventing the wiring from taking the spiral shape that is harmful to
possible inductive effects on the electronics.
❑If it’s necessary to extend the probes, conductors must be used with a
suitable section and in any case not less than 1mm2.
❑For connections to the electrical panel, cables with a section suitable for
the current passing through them must be used. The degree of insulation
must also be compatible with the applied voltages. Prefer cables with
flame retardant insulator and with a low emission of toxic fumes if
affected by fire.
❑It’s mandatory to connect the clamp marked with the initials PE to the
ground system of the power supply network. If necessary, check the
efficiency of the ground system.
❑Other conductors with the exception of the external protection conductor
must not be connected to the PE terminal.

PRE-USE CHECKS
❑After having carried out the wiring, check the correct execution of the
same by means of the wiring diagram.
❑Make sure that the screws on the clamps are properly tightened.
❑Check, when possible, the correct functioning of external protection
devices.
❑Make a correct calibration of the motor protection switch (if present)
dedicated to the compressor motor, as indicated in the following chapter.
❑After turning on the electrical panel, check the correct current absorption
of the various loads. After operating the system for a few hours, it is
advised to check the correct tightening of the terminal board screws
(including the connection of the power supply line).
Caution: before carrying out this operation, the panel must be switched
off by cutting off the supply line upstream and blocking the sectioning
with a padlock to ensure maximum safety. Check the absence of voltage
with a Tester before any operation.

COMPRESSOR MOTOR CIRCUIT BREAKER CALIBRATION
Below we show step by step how to correctly calibrate motor circuit breaker dedicated to
the compressor.
Fig.15: When the system is started for first
time it’s suggested to calibrate the
motor circuit breaker on the
compressor power circuits. Using
an ammeter verify the effective
absorption.
Fig.16: Make the motor circuit breaker
calibration basing on the
measured absorption. Anyway, the
set-up value must not be higher
than the one expected by the
compressor manufacturer.
Caution: incorrect calibration may
cause compressor failure or
unwanted action of the motor
protection switch.
Fig.17: To carry out the calibration, use
the adjustment screw on the
front of the motor protection
switch.
