Ground
The grounding connection can be found on the bottom of the APC620 systems. The M4 self-
locking nut can be used, for example, to fasten a copper strip that is built into the APC620 at a
central grounding point in the switching cabinet or system. The largest possible conductor cross
section should be used (at least 2.5 mm²).
Also see the section "Grounding concept", on page 214.
Starting current
Quick switching on/off of the power supply
If the APC620 is in Standby mode (e.g. Windows XP shutdown), then buffering takes a little more
time due to capacitors and low power consumption. If the "Power Loss Control" option is set to
"Power On" or "Last State" in BIOS, then a system with one of the system unit revisions in table
Caution!
The pin's connection to the functional ground (pin 2) should be as short as possible
(e.g. in the switching cabinet). We recommend using the largest possible conductor
cross section on the supply plug.
