SAFETY SECTION

This Safety Section should be read before commencing any work on the equipment.

Health and safety

The information in the Safety Section of the product documentation is intended to

ensure that products are properly installed and handled in order to maintain them in a

safe condition. It is assumed that everyone who will be associated with the equipment

will be familiar with the contents of the Safety Section.

Explanation of symbols and labels

The meaning of symbols and labels that may be used on the equipment or in the

product documentation is given below.

Installing, Commissioning and Servicing

Equipment connections

Personnel undertaking installation, commissioning or servicing work on this equipment

should be aware of the correct working procedures to ensure safety. The product

documentation should be consulted before installing, commissioning or servicing the

equipment.

Terminals exposed during installation, commissioning and maintenance may present a

hazardous voltage unless the equipment is electrically isolated.

If there is unlocked access to the equipment, care should be taken by all personnel to

avoid electric shock or energy hazards.

Voltage and current connections should be made using insulated crimp terminations to

ensure that terminal block insulation requirements are maintained for safety. To

ensure that wires are correctly terminated, the correct crimp terminal and tool for the

wire size should be used.

Before energizing the equipment, it must be grounded (earthed) using the protective

ground (earth) terminal, or the appropriate termination of the supply plug in the case of

plug connected equipment. Omitting or disconnecting the equipment ground (earth)

may cause a safety hazard.

The recommended minimum ground (earth) wire size is 2.5 mm2 (#12 AWG), unless

otherwise stated in the technical data section of the product documentation.

Before energizing the equipment, the following should be checked:

Voltage rating and polarity

CT circuit rating and integrity of connections

Protective fuse rating

Integrity of ground (earth) connection (where applicable)

Equipment operating conditions

The equipment should be operated within the specified electrical and environmental

limits.

Current transformer circuits

Do not open the secondary circuit of a live CT since the high voltage produced may be

lethal to personnel and could damage insulation.

Insulation and dielectric strength testing

Insulation testing may leave capacitors charged up to a hazardous voltage. At the end

of each part of the test, the voltage should be gradually reduced to zero, to discharge

capacitors, before the test leads are disconnected.

Do not attempt to perform installation, maintenance, service or removal of this device

without taking the necessary safety precautions to avoid shock hazards. De-energize

all live circuit connections before work begins.

Fiber optic communication

Where fiber optic communication devices are fitted, these should not be viewed

directly. Optical power meters should be used to determine the operation or signal

level of the device.

WARNING: EMISSIONS – CLASS A DEVICE (EN55011)

This is a Class A industrial device. Operation of this device in a residential area may

cause harmful interference, which may require the user to take adequate measures.

DECOMMISSIONING AND DISPOSAL

1. Decommissioning

The auxiliary supply circuit in the equipment may include capacitors across the supply

or to ground (earth). To avoid electric shock or energy hazards, after completely

isolating the supplies to the meter (both poles of any dc supply), the capacitors should

be safely discharged via the external terminals before decommissioning.

2. Disposal

It is recommended that incineration and disposal to watercourses is avoided. The

product should be disposed of in a safe manner. Any products containing batteries

should have them removed before disposal, taking precautions to avoid short circuits.

Particular regulations within the country of operation may apply to the disposal of

lithium batteries.
