2.3 Voltage tap when using multiple NZM-XMC-TC-MB devices
If you are using multiple NZM-XMC-TC-MB modules, you can use a single
voltage tap and connect it to multiple modules. In this case, the voltage tap
must be connected to the mains either directly or via a voltage transformer
with appropriate fuse protection. It then needs to be connected to the
modules in parallel using terminals 10 to 13.
The wiring must follow the schematic diagram in
Figure 6: Wiring for multiple NZM-XMC-TC-MB modules
→
Take into account the maximum cable length and the associated
voltage drop.
