Red light shining slightly in use shows feed part of the network port is off-loads, can judge there is a glitch of the power supply or far-end equipment. Installation and Commissioning 1. Insert the input power line into 110--220VAC introducing input socket. 2. Connect output signal line respectively 3. Connect communicating & introducing line, signal wire, output lines tightly to avoid bad contacts and loose. Note: Item 1: The installation site must be away from heat source and electromagnetism interference source, non-corrosive gas and metal dust. Item 2:Mustn’t block the cooling hole of the equipment. Item 3: Installation must be stable fixed placing, not a violent shock. Item 4: Note whether the AC input voltage is during the range of 100VAC 280VAC. Item 5: Prevent to crash and conflict with other equipment during the installation, so as not to cause local damage of the machine surface. Boot Test 1.Using resistance gears of millimeter to detect Ac input, short circuit phenomena did not exit; after loading, green light in output interface is on shows output normally. If it is off after several seconds shows short circuit and limited flow phenomena did exit. 2. After electric communication, the working light in front board is on. Daily maintenance and maintenance: Long-distance power supply PROCET PT-PSE801G-T can work uninterruptedly,to guarantee the reliability of the power supply, must prepare daily maintenance work, make the power system in the best working state. 1. Clean power source regularly to prevent dirt retention phenomenon 2. Check whether the connecting line of input and output is loose or contact undesirable, if damaged, please change in time. Storage: When storing, must be kept in dry warehouse, not exposure to sun and rain. Storage temperature:-5°C +55°C (low temperature storage recovery time is at least 4 hours), Relative humidity:5% 90%RH
