  • Charger-to-junction "J" cable in parallel: same size as the single output cable. 6 cells (12 V) or 12 cells (24 V).
  • Single charger: output wires max 4 meters. Parallel: charger-to-junction cables equal length, never over 2 m; junction to battery under 6 meters.

Location & Supply

  • As close to the batteries as possible, dry and airy; horizontal or vertical with the output connector facing down (vertical preferred). Parallel units side by side.
  • At least 5 cm clearance all round (excluding the base); screws strong enough for the weight.
  • Rechargeable lead (open or sealed), Gel, AGM, Optima® and Li-Ion batteries only.
  • AC cord supplied: brown/black 1 live, blue/black 2 neutral, yellow-green earth. Fit an overvoltage category III switch for on/off; check the rating label matches the mains.
  • Disconnect AC (bipolar switch) and the batteries (isolator) before touching the DC terminals. Batteries gas while charging: ventilate, no sparks or flames. Check polarity: reversal can seriously damage the charger.

Outputs

  • Single: battery positive to an output positive, battery negative to the charger negative, using the supplied connector. With one or two banks always use MASTER (main output) – ideally for the most-used (service) bank. Leave unused outputs free: do not bridge them.
  • Parallel (current sharing): MASTER to junction JM, SLAVE 1 to JS1, SLAVE 2 to JS2, negatives to JCN; each junction to its battery.
  • Current sharing needs at least one RDS 1562 terminal (optional) to set group and priority.
  • Battery temperature sensor KTBRJ on the RJ11 socket (disabled automatically if a KTB4N interface is connected).

  • Pin 4 status: high impedance = charger off or manual-reset fault; ≈ + 13,6 Vdc = on, no manual-reset fault.
  • Battery selector (front panel, charger off): 0 EL open (factory), 1 EL sealed, 2 GEL, 3 AGM, 4 Optima®, 5 Li-Ion; 6–9 reserved.

LEDs & Charging

LED State Meaning
STATUS Off / green / orange / red No mains or active error / FLOAT / ABSORPTION / BULK
STATUS Quick / slow flash Power reduction / charge compensation
STATUS Short green pulse / green pulse Monitor mode / stand-by
ERROR Off / flashing / red No problem / manual-reset problem / automatic-reset problem
OUT CURRENT Green, orange, orange, red >2%, >25%, >50%, >75% of max current (flashing in current sharing)
  • BULK: constant current at maximum (or reduced) rating. ABSORPTION: constant voltage until current drops below the ABSORPTION–FLOAT threshold (factory 20% of max current). FLOAT: maintenance voltage.
  • In parallel, IMAX and the threshold are multiplied by the number of chargers (2 or 3).

Fault Codes (ERROR LED flashes)

Flashes Problem Action
1 Output short circuit or overload (auto reset) Check output wiring, battery bank and loads
2 Output fuse open (likely reversed battery polarity) Quick service center
3 Output overvoltage Quick service center
5 Extended output overload Check battery bank and loads
6 Both fans blocked Quick service center
9 Two chargers in a group with the same priority Check group and priority with the RDS 1562
10 Both internal temperature sensors faulty Quick service center
11 BULK phase over 8 hours (default) Check batteries and loads
12 ABSORPTION phase over 24 hours (default); output held at FLOAT Check batteries and loads
  • Manual reset: remove the cause, disconnect AC for 10 seconds, reconnect.
  • Automatic-reset problems (red ERROR LED): over temperature, blocked fan, AC low (below 207 Vac HR / 108 Vac FR: output limited to 70%), AC fail (below 161 Vac HR / 83 Vac FR), cold battery (< –15°C), hot battery (> +50°C), sensor fault, CAN error.
  • Maintenance: none; check cables and connections once a year.
