Note that with the instrument powered on, the terminals could be dangerous to
touching and cover opening actions or elements removal may allow accessing
dangerous parts. Therefore, the instrument must not be used until this is
completely installed.
The instrument must be connected to a power supply circuit protected with gl
type (IEC 269 ) or M type fuses rated between 0.5 and 2 A. This circuit should be
provided with an automatic switch or any equivalent element to disconnect the
instrument from the power supply network. The supply and measuring voltage
circuits will be both connected through a wire with a minimum cross-section of 1
mm
