This instrument conforms with the following community directives: EMC 2004/108/CE and
LVD 2006/95/CE.
Refer to the instructions in this manual to preserve safety protections.
WARNING: If this instrument is not installed and used in accordance with these
instructions, the protection provided against hazards may be impaired.
To meet the requirements of EN 61010-1 standard, where the unit is permanently connected to
main supply, it is obligatory to install a circuit breaking device easily reachable by the operator
and clearly marked as the disconnecting device.
To guarantee electromagnetic compatibility, the following guidelines should be kept in mind:
• Power supply wires should be separately routed from signal wires and never run in the same conduit.
• Use shielded cable for signal wiring.
• Cables section should be
≥
0.25 mm².
Before connecting signal wires, signal type and input range should be verified to be within the
right limits. Do not connect simultaneously more than one input signal to the meter.
