Check if the DIN-Rail mounting kit is installed firmly.Step 1Insert the bottom of DIN-Rail mounting kit (one sideStep 2with spring support) into DIN-Rail, and then insertthe top into DIN-Rail.Tips:Insert a little to the bottom, lift upward and then insertto the top.Check and confirm the product is firmly installed onStep 3DIN-Rail, then mounting ends.【Disassembling DIN-Rail】Device power off.Step 1After lift the device upward slightly, first shift out theStep 2top of DIN-Rail mounting kit, and then shift out thebottom of DIN-Rail, disassembling ends.Notice before power on: Power ON operation: First insert the power supplyterminal block into the device power supply interface,and then plug the power supply plug contact and poweron. Power OFF operation: First, remove the power plug,and then remove the wiring section of terminal block.Please pay attention to the above operation sequence.【Power Supply Connection】The serious of switches top panel provide3-pin 7.62mm pitch industrial terminalblocks, support 1 DC power input, with anti - reverseconnection function. Voltage range: 48VDC (45~55VDC). Thepin definitions of power supply are shown as follows:Pin No. Pin Definition Description1 V+ Positive power input2 FG Shell Ground3 V- Negative power input【DIP Switch Settings】The serious of switches panel provide 4-pin DIPswitch for function setting, where "ON" is enablevalid terminal.
