3: Installation Planning
When several cabinets are connected together to form a parallel-cabinet UPS system they should be positioned as close
together as possible – ideally standing immediately adjacent to each other to form a cabinet suite. The ST-40 and ST-60
cabinets contain internal batteries but the other models require external batteries contained in a purpose designed
enclosure, or rack mounted. Kohler Uninterruptible Power Ltd can provide a range of suitable battery cabinets if required
An external battery enclosure should be located as close as possible to the UPS cabinet(s) to reduce the volts drop on the
DC cables when the batteries are in use – again, in an ideal installation the battery enclosure should be installed adjacent
to the UPS cabinet(s) if possible.
3.2.3 Clearances
Figures 3.1 and 3.2 illustrates the required clearances that must be provided around the UPS cabinet.
Figure 3.1 ST40 - ST120 Clearance recommendations
ST40 - ST120 clearances notes
1. No rear or side access is required for maintenance, servicing or user operation.
2. A clearance of 1000mm is required at the front of the UPS cabinet to allow the UPS modules to be withdrawn (A).
3. A clearance of 200mm must be provided at the back of the cabinet to provide adequate ventilation airflow (B).
4. No side clearance is necessary (C1).
5. The cabinet right-hand door must be opened by 115° in order to remove/fit the UPS power modules so the right-hand
side of the cabinet cannot be positioned directly against a projecting wall – in this case an additional side clearance
must be provided immediately in front of the cabinet right side (C2).
6. A clearance of 400mm should be provided at the top of the cabinet to assist ventilation if the route at the back of the
cabinet is insufficient to dissipate the cooling airflow.
