■Momentary power failure or reset from lightning surge noise
If a momentary power failure resulting from lightning surge noise is detected, this product may be reset. As a measure against
lightning surge noise, connect a surge absorber for lightning as shown below.
Using the surge absorber for lightning can reduce the influence from the lightning.

Precautions
• Separate the ground of the surge absorber for lightning (E1) from that of the product (E2).
• Select a surge absorber for lightning which the power supply voltage does not exceed the maximum allowable circuit
voltage even when line voltage is maximum.
■Uninterruptible power supply (UPS)
Always use an online power system or line interactive system for the uninterruptible power supply.
For commercial supply method uninterruptible power supply systems, use Mitsubishi FREQUPS FW-J low-capacity series
UPS devices.
Precautions
This product incorporates a PFC circuit, therefore do not use a square wave output uninterruptible power supply.
