Insertion and removal with UPS’s operating (hot swap)
The hot insertion and removal of the UPS can only take place if the system is configured with the
RJ45 female/RJ45
female shielded adaptor cable
(as shown in the figures below).
The hot insertion and removal of the UPS makes technical support easier and improves the reliability of the system.
With this procedure it is not necessary to shut down all the UPS’s in order to add or remove a unit.
Hot insertion and removal can only be done on systems comprising UPS’s with the following characteristics:
The UPS system must be prearranged with a distribution panel (for power connections)
The UPS system must be prearranged with a RJ45 female/RJ45 female shielded adaptor cable (not provided with the
UPS)
.
All the UPS’s in the system must have the same firmware version.
Example of hot insertion
A) UPS parallel cable type RJ45
B) RJ45 female/RJ45 female
shielded adaptor cable

UPS).
With the lever of SW1 in the start position in one UPS only and the lever in the cont position on all the others, check
that all the UPS’s are operating normally and that the system is sharing the output power.
