OPZV (TUBULAR GEL)Quick Installation Guide
To ensure optimal performance and maximize the lifespan of your REKOSER ROV2-250 battery, follow these assembly and connection guidelines.
1. Space and Dimension Verification
Before proceeding, ensure the receptacle or cabinet of your equipment complies with the unit's physical measurements:
- Length: 124 mm
- Width: 206 mm
- Height: 354 mm
- Total Height: 390 mm
- Weight: 20.3 kg
2. Terminal Configuration (F10)
- Terminals: Ensure your system's connectors match the F10 type to prevent electrical arcing.
- Polarity: Check the positive and negative markings on the battery before connecting, to prevent short circuits.
3. Charge Parameters
- Cycle use: 2.35-2.40V (-5mV/ºC/cell)
- Float use: 2.25-2.29V (-3mV/ºC/cell)
4. Safety and Storage
Maintenance: Immobilised gel and tubular plate: sealed, no water topping up.
Position: Upright, or horizontal on a rack.
Charging: Keep to the stated charge voltage: gel is sensitive to overcharging.
Storage: Store charged, in a cool and dry place, and recharge periodically.
