Safety precautions:
- Use only isolated tools.
- Do not connect the meter to a 3 phase - 415V AC - network.
- Place the meter only in dry surroundings.
- Make sure the used wires are suitable for the max current the
meter can measure.
- Make sure the AC wires are installed correctly before activating
the current/voltage.
- Do not touch the meter connecting clamps directly with your bare
hands, with metal, blank wire or other material as you will have
the chance of an electricity shock and a possible chance for health
damage.
- Make sure the protection cover is placed after installation and
has been sealed.
- Installation, maintenance and repair should only be done by a
certified electrician.
- Never break the seals or open the front cover as this might
influence the functionality of the meter.
- Do not through, drop, kick or other physical violence to the
meter as there are high precision components inside that will break
or make the meter measure inaccurate.
- Do not mount the meter in area's with harm gas, dust, mildew or
insects or on unstable surfaces.
