Connecting the EBM(s)
To install the optional EBM(s) for a UPS:
A small amount of arcing may occur when connecting an EBM to the UPS. This is normal
and will not harm personnel. Insert the EBM cable into the UPS battery connector quickly and
firmly.
1.
Plug the EBM cable(s) into the battery connector(s) as shown in
figure 7
. Up to four EBMs may be
connected to the UPS.
2.
Verify that the EBM connections are tight and that adequate bend radius and strain relief exist for
each cable.
3.
When using external battery cabinets, the number of EBMs should be set throw the LCD panel in the
"Battery settings" section, see "Configuring battery settings" on page 20.
