Fujitsu PRIMEPOWER850 User Manual page 131

- Electrical ratings of this unit: 100-120 to 200-240VAC, 3.8A to 1.9A per power
cable, 50/60Hz, single-phase
l Reliable earth grounding of rack-mounted equipment should be maintained. If
indirect power connections (e.g. via power strips) are used, earth grounding is
necessary.
Equipment damage
Connect the ground before connecting any of the power supply lines. If all of the
power cables are connected to a single power strip, high leakage current
exceeding the stipulated value may leak through to the earth lead of the power
strip.
If the power strip is not directly connected to the main distribution panel, use a
power strip with an industrial plug.
• General installation notes
l Keep ventilation holes clear of obstructions.
l Install the PCIBOX away from direct sunlight or sources of heat.
l Install the PCIBOX in an environment free of dust, corrosive gas, and ocean spray.
l Isolate the PCIBOX from vibration.
l The AC power supply source must be properly grounded, with a maximum
resistance of 100 Ohms. Also, do not ground the AC power supply source using a
shared ground. Use only an independent grounding point. A shared ground may
cause the PCIBOX to malfunction.
l Avoid running cables beneath a unit and prevent cables from becoming taut.
l Never disconnect the power cable while the unit is powered on.
l Keep objects off the top of the PCIBOX at all times.
l Raise the ambient room temperature slowly in the winter to prevent condensation
in the PCIBOX.
l Use the PCIBOX only after it has warmed up sufficiently.
l Install the PCIBOX away from EM noise generating devices such as photocopiers,
air conditioners, or welders.
l Take electrostatic prevention measures. Note that many carpets generate static
electricity that can cause the PCIBOX to malfunction.
l When moving the PCIBOX, do not pull on the front cover. This could cause
damage to the unit.
l The redundant power configuration or dual power feed configuration of this unit
requires two additional power cables. The redundant power supply configuration
connects the power cables to the same AC power supply. The dual power feed
configuration connects the power cables to separate AC power supplies.
