Metal plate Basic unit T Grounding tiles Expansion unit HOTLAC LA Power Net filter SO L Grounding Earth leakage breaker Insulation Recommended Figure 1 Power wiring example E I O Wiring Procedures Always use the rated input output voltage according to the module specifications Using other voltages may damage the equipment or cause personal injury or fire Use shielded cable and connect the both ends of shields to ground Depending on actual noise environment it could be more effective to connect only one end of shield or not to connect both ends Take a appropriate grounding method accordingly Install AC power cables in separate cable trays or bunches from I O signal or data lines Route the I O lines and data lines as close as possible to the grounded surfaces such as cabinet elements metal bars and cabinets panels E General Wiring Procedures Use copper conductors for all wiring You can use one copper conductor AWG 14 2 1 mm through AWG 22 0 36 mm or two copper conductors AWG 16 1 3 mm through AWG 22 0 36 mm per terminal The suggested torque for terminal connections is 0 5 to 0 6 Nm Use proper cable ferrules for terminals Using improper cable ferrules or connecting bare wires to terminals directly might result in fire Do not turn on the power supply to a broken PL2.
