4.3.4 DC Wiring instructions
In the UPS-cabinet of the Conceptpower DPA 500 there is no space provided for batteries, therefore the battery
will be external in either in cabinets or in shelves/racks.
Batteries can be either separate for each module or common battery within the same frame. It is normally
recommended for redundant Multi-Module systems to provide each UPS-Module with its own separate battery.
Before proceed with the wiring, make sure you have read and understood the chapter 4.2 Electrical installation.
To ensure protection of the personnel during the installation of the UPS make sure that the connections are performed
under the following conditions:
• No mains voltage is present in the UPS
• All the loads are disconnected
• The UPS and the external battery are voltage-free
To verify the complete shutdown of the Conceptpower DPA 500 perform following steps:
• No mains voltage is present
• All Loads are shut down and disconnected
• UPS is shut down and voltage-free
• Maintenance Bypass IA1 is open and in position OFF;
• All 5xparallel Isolators IA2-1, IA2-2, IA2-3, IA2-4, IA2-5 are in position OFF (open)
• All 5xbattery breakers F3-1, F3-2, F3-3, F3-4, F3-5 are in position OFF (open)
• Make sure the battery fuses in the external battery cabinet and on the UPS are open.
Achieve the DC battery wiring according to the following instructions, by making sure the correct wires are used
and the cables are tightened with the correct torque, as stated in the tables 8 and 10:
1. COMMON BATTERY – Connect the PE wire(s) and then connect the battery wires, make sure the
polarity (+) and (-) is respected!
