1.1.1. Operational safety
Caution! Removal of the meter housing during the warranty period voids the warranty.
The assembly and the installation of the electrical connections may be carried out only by a
duly qualified electrician.
Always check the connections before turning the meter on.
Prior to removing the analyzer housing, always turn the supply off and disconnect the
measurement circuits.
The device is intended for installation and use in industrial electromagnetic environments.
A switch or a circuit-breaker should be installed in the building or facility. It should be
located near the device, easily accessible to the operator, and suitably marked.
