Typical Cable Connection Scenarios
NOTICE
1. If the SmartLogger communicates with an inverter over an AC power cable, the power line
communication (PLC) central controller (CCO) module needs to be connected to the SmartLogger.
In addition, a miniature circuit breaker (MCB) and a knife switch need to be installed between the
PLC CCO module and the busbar to prevent device damage in the case of short circuits.
2. If the SmartLogger communicates with an inverter over an AC power cable, the cable from the
knife switch to the MCB and the cable from the busbar to the knife switch both need to be
prepared by yourself. Recommended cable: three-core armor cable with the operating voltage to
the ground greater than or equal to 600 V and the cross-sectional area of a single core wire being
2
4 mm .
3. The network cable delivered with the SmartLogger is 2.2 meters long. Determine the installation
position of each component based on the cable length.
