Installation and Use
1 Please install a power meter indoors in a dry and good ventilation environment, the base plate used to install the power meter should fixed on a solid and fire-resistant wall that is stable. recommended install height is about 1 8 meter. or install in dedicated distribution box 2.111S necessary to connect the wire according to the wiring diagram on the end box. we recommend you to connect with the copper joint to avoid the power meter being burned for the poor contact of the copper joint in the end box 3 Lightning protection measures are necessary which power meter is used at the place where a thunderstorm is frequent to avoid the meter from being burned when struck by lightning
Storage and Transportation
1 Store the power meter with the anginal packaging. storing environment
temperature should be within -25 C-.70 C. relative humidity should be lower
than 85% and the au should not contain gas which may cause erosion.
2. This product is an electronic device, please avoid heavy objects impact
and bumping when transporting and carrying it. 3 When the outer case of the
power meter has obvious cracks caused by severe shock or drop from high
position dunng the transportation carrying and instalation, please do not
connect wires to this power meter.
Quality Assurance
Within a year after the manufacture date of the power meter. when a user discovers the power meter cannot meet the national standard with the condition that the user use the meter according to the user s manual and the outing case is complete our company will repair or replace the meter free of charge.
