Suggestion for installation & Disassemble
◆Cutoffthe power of the machine to ensure that there is no dangerous voltage inside the machine, except for lighting and spare sockets.
◆The product adopts 35mm DIN rail to install and fix.
◆Connect the cables according to the wiring drawing of the safety relay.
◆Before powering on, check whether the cable connection is correct and whether the relay is fastened to the mounting rail.
◆The power supply of the machine must be cut off before disassembling the safety module.
◆Loosen the locking screw or remove the terminal.
