© Landis+Gyr
Issue: 1.8
The following safety regulations must be observed at all times:
This equipment does not contain a disconnection device. Means

for disconnection from the 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 overcurrent protection device.

Overcurrent protection must be provided as part of the building
installation. Maximum overcurrent device rating is 100 Amp at 415
Volts, conforming to the requirements of BS1361, or equivalent.
The maximum rating of the meter is 100A and requires connecting

conductors of 25mm2. Failure to do so could result in irreparable
damage to the meter. If smaller connecting conductors are used an
appropriate mains fuse must be used.
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 meters must be held securely during installation. They can

cause injuries if dropped.
Meters that have 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 meters must on no account be cleaned with running water or

with high-pressure devices. Water penetrating can cause short-
circuits.
 The meter terminal cover should be secured in place before any
load is supplied.
