<Do not install the monitor in a place where maintenance of the monitor cannot
be performed or where handling the monitor involves dangers.>
Regular maintenance of the monitor must be performed. Do not install the monitor in a place where
the machinery must be stopped when maintenance is performed, where parts of the machinery must
be removed to perform maintenance, or where the monitor cannot be removed because racks or
other things prevent access to it. Do not install the monitor in a place where maintenance involves
dangers (for example, near a high-voltage cable).
4-2. Precautions for system designing
Note the following precautions for system designing of the monitor.
Using a stable power supply
The external output and alarm contact of the monitor may be activated when the power is turned on,
when momentary blackout occurs, or when the system is being stabilized. In such cases, use a UPS
(uninterruptible power system), or take appropriate actions on the receiving side.
The monitor must be provided with the following power supply.
Power supply voltage 100 - 120 VAC ±10% (50/60 Hz) or 24 VDC ±10%
Allowed time of
momentary blackout
Up to 10 milliseconds (To recover from the momentary blackout for 10
milliseconds or more, restart the monitor.)
Example of actions:
To ensure continuous operation and activation, install a UPS
(uninterruptible power system), etc. outside the monitor.
Others
Do not use it with a power supply that has a large power load or high-
frequency noise. If necessary, use a line filter to avoid the noise
source.
CAUTION
• An unstable power supply and noise may cause malfunctions or false alarms.
