Warnings
DANGER! Live parts. Heart attack, burns and other injuries.
- Disconnect the power supply and loads before connecting/disconnecting the electrical wires and installing or servicing current transformers.
- Only use the analyzer at the specified voltage and current.
- The analyzer should only be installed by qualified personnel experienced in working in safety.
- Access to the terminals is reserved for qualified personnel for maintenance operations.
NOTICE: The system installer is liable for the safety of any system that
includes the analyzer
NOTICE: Always use electrical wires according to all applicable local and
international regulations.
NOTICE: only use the analyzer at the specified voltage and current to
avoid permanent damage.
NOTICE: no one is authorized to open the analyzer. 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 analyzer installation. It must be kept in good condition and in a clean location accessible to all operators.
Cleaning

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 analyzers other than those indicated in the provided
instructions void the warranty.
Notes
- The instrument must be installed taking care of leaving the external disconnecting device easily accessible.
- The current transformers may not be installed in equipment where they exceed 75 percent of the wiring space of any cross-sectional area within the equipment.
- Restrict installation of current transformer in an area where it would block ventilation openings.
- Restrict installation of current transformer in an area of breaker arc venting.
- Secure current transformer and route conductors so that they do not directly contact live terminals or bus.
- An external switch or circuit-breaker that must be mounted near the instrument is required.
- For use with Current Sensors rated for basic Insulation.
- To be used in a pollution degree 2 or better environment only.
- Indoor use only.
- Auxiliary inputs/outputs (Digital input, Digital output, RS485, M-Bus) must be connected only to Limited-Energy Circuit in accordance with IEC/EN 61010-1.
- The product is intended to be installed inside a certified fire/electrical enclosure.
Additional UL notes
- For use with Listed or R/C Energy Monitoring Current Sensors rated for basic Insulation.
- Auxiliary inputs/outputs (Digital input, Digital output, RS485, M-Bus) must be connected only to Limited-Energy Circuit in accordance with UL/CSA 61010-1 or Class 2 supply source which complies with the National Electrical Code (NEC), NFPA 70, Clause 725.121 and Canadian Electrical Code (CEC), Part I, C22.1.
