4. Installation Requirements:
4.1.1 Wall mounted, has three fixed holes, can be fixed on the wall surface.
4.1.2 Collector should be installed in the building, if outdoor installation, should configure the outdoor protective box, in avoid the direct sunlight and rain.
4.1.3 Collector should be installed the at the position which the meter is relatively concentrated.
4.1.4 The power supply of collector should be stable, in avoid the data can’t be collect caused by the power outage. The power line adopts the 2×0.5mm2 thickness or thicker wires, and install the earth-leakage protective device.
4.2.1 The antenna will be installed at the outdoor or outdoor relative open position, and antenna is towards the concentrator.
4.2.2 The antenna will be within the scope of effective protection of lighting rod and will be more than 1.5 m below than lighting rod.
4.2.3 Install the corresponding frequency antenna according to the antenna terminal instruction on the collector case. Must guarantee the upward and downward antenna communication frequency, channel, concentrator, smart meter correspond strictly when installation. The communication frequency of sucker antenna will be checked the label at the bottom of antenna.
4.2.4 Antenna bracket fixed well, and the antenna base will be fixed firmly on the bracket. Tight the magnet part of antenna head, and also tight firmly the junction between the antenna and collector.
4.2.5 In order to avoid the antenna was surrounded by the metal objects. The antenna position should be far away from the air conditioner compressor, transformer, communication cable,etc.
