3 Termination switch. The devices at the ends of the fieldbus must have termination
on. All other devices must have termination off.
4 Biasing switch. One (and only one) device, preferably at the end on the bus must have
the bias on.

Connecting motor temperature sensors to the drive

IEC/EN 60664 requires double or reinforced insulation between the control unit
and the live parts of the motor. To achieve this, use an CMOD-02 I/O extension
module or CPTC-02 ATEX-certified thermistor protection module. Refer to section
Implementing a motor temperature sensor connection
multifunction extension module (external 24 V AC/DC and isolated PTC
interface) (page 454).
