WARNING
To ensure correct operation of the UPS and its ancillary equipment it is necessary to provide the appropriate wiring and with fuse
protection in accordance with the prescribed local standards or with the local regulations/law. Alternatively refer to the suggested
appropriate wiring and fuse protection in the following sections.
The DPA 500 UPS is 3W + PE. The UPS can accommodate L-L loads only, NOT L-N. The UPS unit has the following power connections:
Rectifier input: three-phase (1-L1, 1-L2, 1-L3)
Bypass input: three-phase (2-L1, 2-L2, 2-L3)
Neutral (N) Neutral connection at UPS input (upstream) is NOT available as standard. Please consult factory for 4W+PE installations.
Note:
For parallel cabinet installations, neutral cable must be connected from UPS 1 to UPS 2, to UPS X (where X is the
number of cabinets in parallel). The Neutral is between ups cabinets only and is not for distribution to downstream
equipment.
IMPORTANT
Load Output: three-phase (3-L1, 3-L2, 3-L3)
Battery: (+) and (-)
Note: The battery (-) is at the same potential and is the same connection point as N.

Wiring Configurations
Conceptpower DPA 500 can be factory-wired in different configurations.
The AC wiring (rectifier input, bypass input and output) has the following possibilities:
DITE - Dual Input Top Entry
DIBE - Dual Input Bottom Entry
SITE - Single Input Top Entry
SIBE - Single Input Bottom Entry
Each of these, in turn, can be configured with or without centralized input disconnects.
The DC wiring (battery) will be located ideally for the applicable top or bottom entry, matching the AC wiring access by default.
Two gland plates are provided at both the top and bottom of the cabinet. The forward gland plate is for DC wiring and for AC output
wiring. The rear gland plate is ideal for AC inputs (rectifier and bypass).
