Warnings
DANGER! Live parts. Heart attack, burns and other injuries.
- Disconnect the power supply and loads before connecting/disconnecting the electrical wires.
- The transducer should only be installed by qualified personnel experienced in working in safety.
- Access to the terminals is reserved for qualified personnel for maintenance operations.
- The system installer is liable for the safety of any system that includes the transducer
NOTICE: only use the transducer at the specified voltage and current to
avoid permanent damage.
NOTICE: no one is authorized to open the transducer. This operation is
reserved exclusively for CARLO GAVAZZI technical service personnel. Protection
may be impaired if the instrument is used in a manner not specified by the
manufacturer
This manual is an integral part of the product. It must be consulted for
transducer installation. It must be kept in good condition and in a clean
location accessible to all operators.
Cleaning
Disconnect the power supply and loads before cleaning. Use a slightly dampened
cloth to clean the transducer. Do not use abrasives or solvents.
Responsibility for disposal
The product must be disposed of at the relative recycling centers specified by
the government or local public authorities. Correct disposal and recycling
will contribute to the prevention of potentially harmful consequences to the
environment and persons.
Service and warranty
In the event of malfunction, fault, requests for information or to purchase
accessory modules, contact the CARLO GAVAZZI branch or distributor in your
country. Installation and use of transducers other than those indicated in the
provided instructions void the warranty.

UL Notes:
All the devices shall be installed in a pollution degree 2 environment or
better. For power supply terminals 5,6 voltage inputs terminals 2,3
communication terminals 7,8,9: use 75°C copper (CU) conductor with wire size
13-20 AWG (0.5 to 2.5mm^2) stranded or solid. Terminal tightening torque of
4.4 Lb-In (0.5Nm) For current terminals 1,4 with maximum input current up to
600A:
Use minimum 120°C copper (CU) conductor with double wire size 300 AWG
(150mm^2) stranded or solid or double busbar size 30mm x 5mm. Terminal
tightening torque of 177 Lb-In (20Nm) For current terminals 1,4 with maximum
input current below 600A:
Use minimum 120°C copper (CU) conductor with wire size or busbar size
evaluated in the end product in order to guarantee the wire or busbar
temperature below 120°C. Terminal tightening torque of 177 Lb-In (20Nm)
The suitability of the connection between the shunt and the end-use busbar
shall be evaluated in the end product. A short circuit current rating matching
that of the system where this device is installed must be tested if the shunt
is relied upon for continuity of the busbar
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired
