The PTC input is reinforced/double insulated. If the motor part of the PTC sensor and wiring
are reinforced/double insulated, voltages on the PTC wiring are within SELV limits.
If the motor PTC circuit is not reinforced/double insulated (ie, it is basic insulated), it is
mandatory to use reinforced/double insulated wiring between the motor PTC and CMOD-
02 PTC terminal.
