Only qualified specialists or technicians who conform to applicable safety

standards may carry out the installation of this equipment. The installation must

further comply with all local legislation and regulations.

Follow all installation and safety instructions very carefully, otherwise those

performing installation may suffer from a hazardous situation and the UPS or

load connections may also be damaged.

The high voltage and current contained within the UPS equipment can injure

or kill personnel and damage equipment.

For electrical installation, closely observe the nominal current rating of the source.

Installing External battery cabinets

z First disconnect the UPS from mains and loads before attempting an

External Battery Cabinet installation.

z Use the battery cable provided with the External Battery Cabinet to

connect the External Battery Cabinet to the UPS. Connect a second

battery cabinet to the first one with the cable provided if more than one is

to be installed.

z Be aware of UPS parameters and changing the Battery pack quantity

when using the external battery cabinets (see chapter 7.2)

Installing UPS

z Ensure that the installation site has all electrical connections properly

carried out. In addition, refer to figures 2 and 3 to check the fuse and

cable dimensions.

z Isolate and secure the source against reclosing. Both input and output

circuit breakers (located in the back) must be “OFF”.

z Refer to figure 2 for single cable input and figure 3 for dual cable input.

Connect the UPS according to these diagrams. If installing dual cables,

the interconnection jumper (b*) needs to be removed as in figure 2. Fuse

and cable sizes are given in figure 3.

z During installation, if it cannot be determined that neutral is grounded or

the identification of the neutral status of the mains supply is unreliable,

an additional two pole disconnect device is necessary in the building

installation.

z At the back of the unit you will find the Emergency Power Off (EPO),

which when open will immediately shut down the logic circuit output of

the UPS as in figure 2 and 3. Wiring the EPO signal is optional.

z Caution! Local safety requirements may require a separate external

Emergency Power Off that opens output circuit breakers, and if so, use
