Dangerous voltage on conductors
The connecting wires at the place of installation must not be live when
fitting the meter. Touching live parts is dangerous to life. The main fuse
should be removed and kept in a safe place until work is completed, so that
it cannot be replaced by anyone unnoticed.
No overcurrent protection and automatic disconnection
As the meter has no internal overcurrent protection and no method of dis-
connection from the mains, this must be provided by the end installation.
Protect disconnector against overcurrent
In case the meter has a disconnector, this must be protected against over-
current. As the disconnector is not equipped with a thermal and/or short
circuit protection device, it needs to be protected with an external fuse or
overload switch.

.
The meter should be mounted as follows on the meter board or similar de-
vice provided for this purpose (see also

underneath the holes to be drilled.
2.
Determine the desired form of fixing (open or covered meter mounting).
