Cascading chargers

You can cascade up to five CHG 70N-C chargers and operate them with a single power supply and a single network connection. This minimizes the cabling required for larger systems.

The power must be supplied via the NT 12-35 CS power supply unit. Power over Ethernet (PoE) is not possible when cascading.

To cascade the chargers:

Make sure that no chargers are connected to the power before you start.
Plug the chargers into each other as shown in the figure.
Detach the connecting rail on the bottom of the charger.
Fasten the connecting rail beneath two chargers as shown in the figure.
The power and the network connection are passed on to all devices via the connecting rails.
Connect the first charger in the cascade to the network (see Connecting a charger in a network).
Finally, connect the NT 12-35 CS power supply unit to the first charger in the cascade (see Connecting/disconnecting the charger to/from the power supply system).
