Setup and Wiring
■ Thick Cables and Multi-drop Connections Using Multi-branch Parallel
Connectors
Multi-drop connections are possible when using 3G3MV-PDRT2 with an Inverter (except 5.5-kW or
7.5-kW models), by using the following connectors.
Note These connectors cannot be used with the following models. Use the T-branch Connectors
shown in 3-2-3 Connecting Communications Cables to T-branch Taps instead.
• 3G3MV Series (5.5-kW and 7.5-kW models)
•3G3RV Series
•3G3FV Series
3-2-6 Supplying Communications Power through T-branch Tap
When supplying the communications power supply through a T-branch Tap, attach the power supply
cables V+ and V- lines just like the communications lines. When there is a communications power
supply at just one point, connect the shield wire and ground line (100
Ω max.) at the same time as
shown in the following diagram.
