Safety Information
Avoid Hazardous Configurations
Example of the
potential hazard
1. An administrator uses the remote switch connected to the
Remote Power-Off Device to turn off the output power
from a UPS, but the UPS continues to receive utility
power.
2. From an interface of an APC accessory device, a user
issues a command for the UPS to begin providing output
power.
3. Although the remote switch connected to the Remote
Power-Off Device is off, the UPS provides output power
briefly and then turns off again, providing output power
that is potentially dangerous to anyone servicing attached
devices.
Accessory
devices that can
override the
RPO
The following APC accessories can cause a brief override to a
a UPS output turnoff initiated by the Remote Power-Off
Device:
• Network Management Card (AP9617, AP9618, AP9619)
• PowerView (AP9215), the display interface on many
APC products
• Out-of-Band Management Card (AP9608)
• Two devices that are no longer sold by APC but that
might still be a part of your system:
– Web/SNMP Management Card (AP9606)
– PowerNet SNMP Adapter (AP9605)
Note
In many case, an APC accessory device has a
built-in Network Management Card, which
does not have its own separate part number.
