MAINTENANCE
For best system performance, the following inspections and maintenance tasks are recommended to be carried out for at least two times a year.
- Make sure no block on airflow around the controller. Clear up any dirt and fragments on radiator.
- Check all the naked wires to make sure insulation is not damaged. Repair or replace some wires if necessary.
- Tighten all terminal screws to the indicated torque; Inspect for loose, broken, or burnt cable/wire connections.
- Check and confirm that LCD is consistent with required. Pay attention to any troubleshooting or error indication. Take corrective action if
necessary.
- Make sure all system components are effectively and tightly connected to ground.
- Check all terminals for any corrosion signs, damaged insulation, increased temperature, or carbonization/discolored signs.
- Check for any dirt, nesting insects and any corrosion signs. Implement corrections actions as early as possible.
WARNING: Risk of electric shock! Make sure that all the power is turned off before above operations,
and then follow the corresponding inspections and operations

MANUAL DE USUARIO CONTROLADOR CEDRO PLUS
Description
The controller will limit charging power to the rated level.
Cuando hay cortocircuito fotovoltaico, el controlador dejará de carga. Remueva el cortocircuito para
regresar a la operación normal.
When PV short circuit occurs, the controller will stop charging. Remove it to resume normal operation.
Fully protection against PV reverse polarity, no damage to the controller. Correct the connection to
resume normal operation.
Fully protection against battery reverse polarity, no damage to the controller. Correct the connection to
resume normal operation.
Should there are other energy sources to charge the battery, when the battery voltage exceeds 15.8
/ 31.3/62.3V (Overcharge protection voltage of lithium battery equals target voltage plus 0.2V), the
controller will stop charging to protect the battery from overcharging damage.
When battery voltage drops to the low voltage disconnect setting, the controller will stop discharging to
protect the battery from over discharging damage.
If the load current exceeds the maximum load current rating 1.25 times, the controller will disconnect the
load.
Once the load short circuit happens, the load short circuit protection will trigger automatically.
The controller detects the internal temperature through internal sensor, when the temperature exceeds
the setting value, the charging current will decrease, and consequently, the controller's temperature;
Should controllers temperature rise and approach over temperature protection threshold, the controller
will stop its operation and resume after temperature lowers/returns to an acceptable level.
