4. INSTALLATION AND CONNECTION:

1. The meter shall be installed in the dry area with good ventilation condition to ensure safety and reliability during installation and operation. If the meter shall be installed in the area with dirty and easily gets damaged, the metering box should be configured to protect meter against the dirty environments.

2. The dimension of meter is as below: the holes should be digged ahead accord with the size and the meter bottom should be fixed on the strong, fire-proof subjects.

Safety precautions:
＊ Use only isolated tools.
＊ 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.
