Figure 3.1 UPS Space Recommendations
Notes
1. The minimum 200mm space shown at the rear of the UPS [Y] is required to allow adequate cooling air flow;
however, the type ‘A’ UPS cabinet is cabled from the rear and the UPS power switches and fuses are located on
the back panel. When installing a type ‘A’ UPS cabinet you should allow sufficient slack in the cabling to pull the
UPS cabinet forward, or otherwise install the UPS with sufficient rear clearance to allow cable and switch access.
2. The above diagram shows 600mm clearance [V] between the UPS and optional Battery Cabinet. This is
necessary to gain side access to the UPS for service repair.
In the case of a type ‘A’ UPS cabinet, if the cabling is sufficient to allow the cabinet to be pulled forward clear of
the Battery Cabinet (
see note 1 above ) then it is not necessary to observe clearance [V], and the UPS and Battery
Cabinets can be located immediately adjacent to each other.
3.3 UPS Power Cabling (preparation and planning)
It is the customer’s responsibility to provide all external fuses, isolators and cables used to connect the UPS
to its input and output power supplies. The following information should help in the planning and preparation
of the UPS power cabling.
The UPS input supply and bypass supply should be connected to the utility mains through a LV-Distribution
board and protected by a circuit breaker or fuse. This provides overload protection and also a means of
isolating the UPS from the mains supply when required. Similarly, the UPS output supply should be
connected to the load equipment via a suitably fused output distribution panel.
The UPS can be wired with a ‘single input feed’ (standard) whereby the UPS input supply terminals are
internally linked to the UPS bypass supply terminals, or it can be wired with a ‘dual input feed’ where the UPS
bypass circuit is connected to a dedicated ‘bypass’ mains supply
(See Figure 3.2) .

*Although the diagram shows 200mm is required at the rear of the cabinet, ‘A’ and ‘B’ cabinets should be
cabled such that the cabinet can be pulled forward to give service access.
