OPZS (FLOODED)Quick Installation Guide
To ensure optimal performance and maximize the lifespan of your REKOSER ROS2-3300 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: 576 mm
- Width: 212 mm
- Height: 771 mm
- Total Height: 826 mm
- Weight: 162 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: 2.20-2.24V (-3mV/ºC/cell)
4. Safety and Storage
Maintenance: Check the electrolyte level and top up only with distilled or demineralised water.
Position: Always upright.
Ventilation: Install in a ventilated room: hydrogen is released during charging.
Storage: Store charged, in a cool and dry place, and recharge periodically.
