LOGO! is a double-insulated switchgear. For LOGO! 0BA6, you do not need to connect an
equipment grounding conductor. For LOGO! 0BA7, however, you must connect its PE
terminal to earth ground.
Circuit protection with AC voltage
To suppress voltage peaks on the power supply lines, you can install a metal oxide varistor
(MOV). Make sure the operating voltage of the varistor (MOV) used lies at least 20 % above
the rated voltage (for example S10K275).
Circuit protection with DC voltage
To suppress voltage peaks on the power supply lines, please install a protection device.
DEHN (order number: 918 402) is recommended.
