Series count and cabinet fit were fixed before the metalwork
Two retained GDF configurations use 16 Deka 12AVR130 blocks at 192 VDC and 20 Deka 12AVR100 blocks at 240 VDC. Equipment record: Deka 12AVR130, companion identifier Deka 12AVR100. Decision: Freeze the 16-block 192 VDC and 20-block 240 VDC string definitions before cabinet fabrication, including polarity, protection, clearances and the exact Deka block dimensions.
Two DC strings, two cabinet definitions
A cabinet drawing cannot start from ampere-hours alone. Series count determines DC voltage, row count influences copper length and protection, and the front-terminal orientation controls service access. The UPS charger and inverter must be compatible with the resulting string before the enclosure is released.
For Deka 12AVR130, the applicability boundary is anchored to 12 V/block, 16 12AVR130 blocks and part Deka 12AVR100. One worked input remains an assumption until it is recorded at the equipment.

Block count, voltage and capacity
The controlling numerical record is: Nominal block voltage: 12 V/block; 192 VDC string count: 16 12AVR130 blocks; First string voltage: 192 VDC; 240 VDC string count: 20 12AVR100 blocks; Second string voltage: 240 VDC; Published 12AVR130 rating: 125 Ah at 8 h; Worked service clearance: 50 mm. Each value has a defined source or assumption status in the engineering ledger. Values from different configurations are not combined as though they came from one installed system.
| Engineering parameter | Value | Evidence status |
|---|---|---|
| Nominal block voltage | 12 V/block | Published OEM value |
| 192 VDC string count | 16 12AVR130 blocks | Anonymized field configuration |
| First string voltage | 192 VDC | Anonymized field configuration |
| 240 VDC string count | 20 12AVR100 blocks | Anonymized field configuration |
| Second string voltage | 240 VDC | Anonymized field configuration |
| Published 12AVR130 rating | 125 Ah at 8 h | Published OEM value |
| Worked service clearance | 50 mm | Worked design assumption |
The two strings differ by four blocks and 48 VDC. That difference changes the charger and inverter interface and cannot be absorbed by cabinet wiring. Series connection adds voltage while the string ampere-hour class remains that of one block; it does not become 16 or 20 times larger.
Series voltage without parallel arithmetic
The worked check uses string voltage = series block count x 12 V. With 16 blocks for the first cabinet and 20 blocks for the second, the result is 192 VDC and 240 VDC. The 48 VDC difference is an electrical design change, not a cabinet option. The arithmetic is reproducible, but it remains a design check until the listed inputs are confirmed at the equipment.
The 192 VDC and 240 VDC result follows from string voltage = series block count x 12 V. If the 50 mm input changes, this check is repeated rather than carrying the earlier result into a different operating state.

Electrical layout before sheet metal
The string drawing numbers every block, marks positive and negative ends and shows inter-tier conductors, disconnect, overcurrent protection and cabinet bonding. Conductor routes are kept short and mechanically protected without blocking access to front terminals.
Mechanical fit uses the exact block outline, terminal projection, cable bend radius, seismic or anchoring requirements, ventilation openings and lifting path. A 50 mm worked clearance is not accepted until the manufacturer and cable design confirm it.
Fabrication inspection confirms shelf spacing and terminal accessibility before batteries arrive. Electrical acceptance then checks polarity progressively during assembly so a complete 192 VDC or 240 VDC error is not discovered at the final connector.
| Path | Technical consequence | Disposition |
|---|---|---|
| Apply the stated engineering decision | Freeze the 16-block 192 VDC and 20-block 240 VDC string definitions before cabinet fabrication, including polarity, protection, clearances and the exact Deka block dimensions. | Selected basis |
| Generic model substitution | Select by family name or rating alone, without confirming the exact configuration. | Not selected on the stated evidence |
| Unverified operating assumption | Treat a design assumption as though it were a site measurement. | Reconsider only if the input changes |

The Deka 12AVR130 decision retains part Deka 12AVR100, the 192 VDC and 240 VDC calculation result and the manufacturer-published 12 V/block point in one equipment record. Applicable OEM instructions, qualified electrical authority and the installed single-line or wiring record remain controlling for any executable work.
Fit, polarity and torque inspection
Acceptance of Deka 12AVR130 depends on five recorded checks:
- Confirm whether the cabinet is the 16 x 12AVR130 or 20 x 12AVR100 design.
- Verify exact block outline, weight, terminals and required installation clearances.
- Check the UPS charger and inverter DC range against 192 VDC or 240 VDC.
- Inspect numbered polarity, disconnect, protection, bonding and conductor routing.
- Measure progressive and final string voltage before connection to the UPS.
The Deka 12AVR130 record is not accepted if part Deka 12AVR100 does not match, the calculation does not reproduce 192 VDC and 240 VDC, or the final operating state is not recorded. The equipment returns to the approved safe state when a check stops, and the unresolved condition remains open without an invented repair result.

A cabinet belongs to one frozen string design
The 192 VDC and 240 VDC cabinets are separate engineered assemblies. A change in Deka model, block count, terminal orientation or UPS DC range reopens both the electrical and mechanical design.
GDF’s UPS service page covers field measurements and service work for Deka 12AVR130.
Decision rule: Freeze the 16-block 192 VDC and 20-block 240 VDC string definitions before cabinet fabrication, including polarity, protection, clearances and the exact Deka block dimensions. A different model, load, voltage, battery string, software version or operating state requires a new check against the applicable manufacturer record.
