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.
10
ML0044B December 1, 2017 Copyright 2017 Bitronics, LLC
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.
11
ML0044B December 1, 2017 Copyright 2017 Bitronics, LLC
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.

group of four. The recommended torque ratings for the terminal block wire fasteners
are listed in the Physical Specifications table (section 1.3).
