Mounting and wiring

KL3403

34

Version: 3.1.0

Fig. 19: Application example - power measurement at a fieldbus station

3.4.3

Application example with frequency converter

WARNING

Risk of injury through electric shock and damage to the device!

Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or
wiring of the Bus Terminals!

The example illustrates power measurement at several three-phase motors that are controlled by a
frequency converter (AC converter), e.g. at a conveyor system. Each motor is monitored by a KL3403.
