2.5 Connecting an emergency stop input device or power meter
The intelligent Touch Manager can perform operations such as an emergency stop of air
conditioners according to the external signal input device, and an electricity usage calcu-
lation for each air conditioner (for power proportional distribution) according to the pulse
inputs from a power meter.
WARNING
• Be sure to perform the operation during power-off conditions. Not doing so
may cause an electric shock.
• Do not clamp high-current cables together with low-current cables.
