4.4  Precautions when Connecting the Uninterruptible Power Supply (UPS) 
 
Connect the Q2ASCPU system to the uninterruptible power supply (UPS), while 
paying attention to the followings. 
 
Use the on-line UPS or line interactive UPS (voltage distortion of 5% or less.) 
Alternatively, use the off-line UPS, i.e., FREQUPS-F series with serial number P or 
later (Mitsubishi). 
Example: FW-F10-03.K/0.5K 
Do not use the off-line UPS other than above.
