CAUTION: Risk of unit damage.
Verify input and control circuits are de-energized before making any connections inside the unit.
CAUTION
WARNING: Risk of electric shock
Exercise extreme care to avoid equipment damage or injury to personnel.
WARNING
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 such as 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. At a minimum, refer to NEC Section 210-20 (A), Table 310-16
for Allowable Ampacities of Insulated Conductors.
WARNING: UPS installation and connections must be performed by a qualified service personnel/electrician.
It is the responsibility of the installation technician to ensure that all local, state and national electric codes are
WARNING
adhered to.
5.5.1
Connections for External Wiring
Use Thomas & Betts or UL listed equivalent two-hole lugs for the phase, neutral, and ground bus bar connections, when the hard-wired
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.

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.
Note:
Overcurrent circuit protection shall be provided by others. The delivery and installation of fuses and
input/output connections of the UPS are at the customer's expense, unless agreed otherwise. Please refer
to Table 8 for recommendations. Consult factory with questions.
IMPORTANT
The Conceptpower DPA 500 UPS is pre-configured at the factory exactly as ordered. Wiring configurations
cannot be changed on site.

Input/Output Ratings and External Wiring Requirements – Common Battery
5.6.1
UPS System Ratings:
The values below are design ratings per phase. Consult the values below when selecting appropriate upstream AC Over Current
Protective Devices (OCPD). ABB OCPDs are recommended; other manufacturer parts are shown for comparison. Ensure that any
selected OCPD will meet the requirements in Table 7. To reduce the risk of fire, only connect UPS to a circuit with recommended OCPD.
