1. Safety Instruction
1.1 Information for Your Own Safety
This manual does not contain all of the safety measures for operation of
this equipment (module, device) because special operating conditions,
local code requirements or local regulations may necessitate further
measures. However, it does contain information which must be adhered to
for your own personal safety and to avoid damage to the equipment. This
information is highlighted by a warning triangle with an exclamation mark
or a lightning bolt depending on the severity of the warning.
Warning
Means that failure to observe the instruction can
result in death, serious injury or considerable material
damage.
Caution
Means hazard of electric shock and failure to take the
necessary safety precautions will result in death,
serious injury or considerable material damage.
1.2 Qualified personnel
Installation and operation of this equipment described in this manual may only
be performed by qualified personnel.
Only people that are authorized to install, connect and use this equipment and
have the proper knowledge about labeling and grounding electrical equipment
and circuits and can do so according to safety and regulatory standards are
considered qualified personnel in the manual.
1.3 Use for the intended purpose
The equipment (device, module) may only be used for the application cases
specified in the catalog and the user manual and only in connection with
devices and components recommended and approved by Finco Electric.
1.4 Proper handling
The prerequisites for perfect, reliable operation of the product are proper
transport, storage, installation and connection, as well as proper operation and
maintenance. When operating electrical equipment, certain parts of this
equipment carry dangerous voltages. Improper handling can therefore result in
serious injury or material damage.
 Only use isolated tools suitable for the voltages the meter is used for.
 Do not connect while circuit is live (hot).
 Place the meter only in dry surroundings.
 Do not mount the meter in an explosive area or exposed to dust,
mildew and/or insects.
 Make sure the used wires are suitable for the maximum current of
this meter.
 Make sure the AC wires are connected correctly before activating the
current/voltage to the meter.
 Do not touch the meter’s connection clamps directly with your bare
hands, with metal, blank wire or other conducting material as that
will cause an electric shock and possibly cause injury.
 Make sure the protection cover is placed after installation.

 Installation, maintenance and repair should only be done by qualified
personnel.
 Never break the seals to open the front cover as this might influence
the functionality or accuracy of the meter, and will void all warranty.
 Do not drop, or allow physical impact to the meter as there are high
precision components inside that may break and render the meter
measurement inaccurate.
