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.
IMPORTANT
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.
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.

5.5 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).

connections are installed. Check bolted joints for tightness. Always use two (2) wrenches when tightening connections to prevent distortion
or damage. Refer to Section 11.10 for the torque specifications.
Insulated conductors of different circuits within the DPA 500 UPS shall be separated by barriers or physically spaced apart. For insulated
conductors, if each conductor is provided with insulation acceptable for the highest circuit voltage, no additional action suchas separation
is necessary. All circuits 24V and less shall be physically spaced one (1) inch apart from voltages 30V and greater. Above all else, power
and control wiring must comply with the NEC and applicable local codes.
5.6 Input/Output Overcurrent Protection
Overcurrent protection (provided by others) must be installed at the distribution panel of the incoming main supply and all branch circuits
and loads connected to the output bus of the DPA 500 UPS. Sizing of circuit breakers, fuses and cables for Input Utility, Output Load and
Battery must meet the requirements of local, state, and national electrical codes. Please refer to Section 5.6.1 and Table 7 for additional
details.
