Grounding - Fujitsu M10 Series Installation Planning Manual

CHAPTER 6 Power Supply Facilities
(10)Power rating (for printer connection)
If a printer is connected to a UPS, selecting a UPS whose power capacitance is
sufficient to connect a printer is needed, by taking account of the following
precautions.
 Input voltage variation of a printer depends on the printing mode.
 Some laser printers requires few times higher than their rated power in toner
fixing.
(11)Checking the UPS environmental specifications and the warranty
term
Other precautions and requirements:
 UPS environmental specification
- Input capacity
- Grounding phase in input one-line grounding
- External dimensions
- Mass
- Amount of heat dissipation
- Earthquake-proofing actions
- Noise level
- Input/output terminals (connector)
 Warranty term
6.4
