Communication interface ports
COM-PORT: X005
The com-port consists of 4 relay outputs from which the following information is available:
– UPS System ON/OFF
– Normal Operation/Bypass Operation
– Normal Operation/Battery Operation
– Battery Voltage OK/Battery Voltage low
One input is for remote shut-down of the UPS system.
Normally, the COM-PORT is used in connection with the automatic shut-down of computers in case
of extended mains failures.
Serial Interface 20 mA Current Loop : X004
This interface consists of a 0-20mA Current loop with galvanic isolation. Information on the UPS-
measured values is available on this interface.
Multicom RS232: X003
X003 is normally used for the optional smartslot, but can be used for other purposes in its place. This
interface also has galvanic isolation and provides information on the UPS condition and measured
values.
Note
For further information on these 2 interfaces, a protocol can be requested from APC.
