4.4.6 Connecting the battery
Figure 4.8 Battery connections (ST-80 cabinet shown)
In the ST-80, ST-120 and ST-200 models the external batteries are connected to terminal blocks located on the left hand
side of the power terminal connection rail. The cables at the top of the terminal blocks are connected to the battery
isolators associated with each UPS module and the terminals at the bottom of the terminal blocks are connected to the
external battery cabinet(s).
The example in Figure 4.8 illustrates the ST-80 cabinet which has four terminal block connections, one for each UPS
module. Each battery string is shown to have three connections annotated ‘+,’ ‘N’ and ‘–’. The ‘N’ connection is connected
to the centre of the battery string.
Note: In the case of the ST-200 each external battery is connected to two UPS power modules so only five sets of battery
connections are provided to cater for the (up to) ten modules. However each UPS power module has an individual battery
isolator located on the back of the UPS Cabinet.
Common battery configuration
If a ‘common battery’ configuration is required, all the UPS modules are fed by a common battery source – which may
comprise a number of parallel battery strings. Where this type of installation is used the ‘common battery’ links must fitted
to the battery terminal block connections as shown in the left-hand diagram of Figure 4.8. These links must be removed for
‘individual battery’ configuration.
IMPORTANT NOTE
The batteries must be installed and connected by an approved Kohler Uninterruptible Power Ltd.
commissioning engineer. High voltage battery strings can be extremely dangerous and should not
be installed by the customer’s installation team.
It is the customer’s responsibility to provide any external DC power cable containment facilities
between the UPS cabinet and battery cabinet where necessary – e.g. cable trays or trunking.
Contact Kohler Uninterruptible Power Ltd. for further installation advice if required.
