Single Input Feed; Dual Input Feed - ABB CONCEPTPOWER CLASSIC DPA-50 User Manual

1.6.1.2

Single Input Feed

To achieve correct Input Cabling see Drawing
For single input feed connect the mains input cable to UPS Terminal Block according to the following table:
MAINS INPUT CABLE
Phase L1
Phase L2
Phase L3
NEUTRAL
EARTH
For minimum recommended Input Cable Sections and Fuse Ratings
Under the connection terminal of the UPS there is a cable-fixing rail to ensure that the cables have been fastened
properly.
1.6.1.3

Dual Input Feed

To achieve correct input cabling see Terminal Block in
NOTE: The UPS is supplied (as standard version) with facilities for a single cable feed (for rectifier and bypass).
If dual feed is required unscrew the terminal bridges between

1.6.1.4 Preparation for the Output Cabling
Before you start connecting the loads, ensure that the sum of the indicated UPS-module rated powers (OUTPUT
POWER) on the nameplates (on the front side of the UPS-modules) is equal to or larger than the total load
requirements.
The output of the UPS must be fitted with circuit breakers or other kind of protection. These circuit breakers will be
connected between the loads and the UPS and will provide additional protection to the UPS in the event of
overloads and short circuits.
These circuit breakers will enable the protection of each load separately.
The size of the circuit breakers depends on the load rating of the load sockets.
The circuit breakers must comply with the prescribed IEC Standards. It is recommended to provide a separate
output distribution board for the load.
