Safety regulations

© Landis+Gyr
The following safety regulations must be observed at all times:

This equipment does not contain a disconnection device. Means for
disconnection from the electricity supply must be provided as part of
the building installation. Do not work on the equipment unless the
supply is disconnected. If disconnection is done by removal of fuses
or other cut-outs, the removed disconnection devices must be kept
secure from replacement while work is performed. If disconnection
is provided by a switch, the switch shall conform to the requirements
of IEC 947-1 and IEC 947-3 or equivalent.

This equipment does not contain an over-current protection device.
Over-current protection must be provided as part of the building
installation. Maximum over-current device rating is 125 A at 415 V,
conforming to the requirements of BS1361 or equivalent. The meter
connections must not be under voltage during installation or when
opening. Contact with live parts is dangerous to life. The relevant
main fuses should therefore be removed and kept in a safe place
until the work is completed, so that other persons cannot replace
them unnoticed.

Only suitably trained and qualified personnel shall be allowed to
work on the equipment. Local safety standards shall be observed
and shall take precedence over these regulations in points of
conflict.

The meter must be held securely during installation. They can cause
injuries if dropped.

Any meter that has fallen must not be installed, even if no damage is
apparent, but must be returned for testing to the service and repair
department responsible (or the manufacturer). Internal damage can
result in functional disorders or short-circuits.

The meter must on no account be cleaned with running water or
with high-pressure devices. Water penetration can cause short-
circuits.

The meter terminal cover should be secured in place before any
load is applied.

To avoid overheating, the meter must be connected using
appropriate cable sizes:

Currents up to 60 A: a cable with a minimum 16 mm
sectional area.

Currents up to 100 A: a cable with a minimum 25 mm
sectional area.

Currents up to 125 A: a cable with a minimum 35 mm
sectional area.
