Connecting the EBM(s)
Note: A small amount of arcing might occur when connecting EBMs. This is normal and will not harm
personnel. Insert the EBM cable into the battery connector quickly and firmly.
Step 1. Plug the EBM power cable(s) into the battery connector(s). Up to four EBMs can be connected
to the UPS.
Step 2. Verify that the EBM connections are tight and that strain relief exists for each cable.
Step 3. Connect the battery detection cable(s) to the connector of the UPS and of the EBM(s).
Step 4. Check that the battery circuit breaker is switched to the "I" (on) position.
This circuit breaker can be put into the "I" whilst the UPS is up and running.
Attention!
When installing the UPS unit's power module, pay attention to any connectors on the
back side of the UPS unit such as RPO and ROO, serial connectors etc. Make sure that
these are not getting damaged!
When installing a UPS unit and any additional EBMs as a tower do not leave any gaps
between any module! This means that any modules must be mounted adjacent to each
other! See also the
installation. This also applies to the tower installation of the UPS units.
Leaving gaps between modules can damage the UPS and any interconnection cables! This
can lead to the UPS unit malfunctioning!
Note that the thick power cables running between the UPS power module and any EBM
carries a high electrical current of a couple of Ampères!
Any damage caused by incorrect physical installation and the subsequent repair work is
