| Product installation |
●Cut off power of machine toensure no dangerous voltage existing, except the lighting and spare sockets. ●Product with35mmDIN rail for installation. ●Connect wire according to the wiring diagram of the safety relay. ●Before power on, please check if all cable rightly connected,and whether relay is fastened to the mounting rail. |
 |
| Disassemble |
●Please cut off power before disassembling the safety module. ●Loosen the screw or remove terminal. |
