Power Supply

Power is supplied to all modules only by supplying power from the external power supply to the coupler and extension power
supply module.
The NZ2FT system has the U
circuit, and U circuit for the system. If the current supplied to the entire NZ2FT system is insufficient, mount an extension

Precautions
• To compliant with UL 248-14, use a UL-approved Type-B automatic circuit breaker (such as ABB Type S201-B16) or use a
fuse with a maximum of 10A protection (such as ESKA Part No. 522.227). Using an inappropriate rated circuit protection
may cause failure.
• The auxiliary power supply, input signals, and output signals cannot be used for the power supply to the slave station.
Doing so may cause failure due to overcurrent.
