75 Automation PC 620 User's Manual V 1.90
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).
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
30 "System unit revisions for at least 10 seconds standby time" might not restart because a
Power Off/On was not detected. To make sure that these system units will restart after a Power
Off/On, the standby time should be set to at least 10 seconds.
Thanks to a workaround, the standby time can be set as needed in systems with one of the
following system unit revisions or higher.
