Connection
1st step: connect the luminaires.
Connect the L+ (brown) luminaire cable to the correct pole, then connect the L- (blue) luminaire cable to
the correct pole. In the case of connection of more than one luminaire, conduct parallel connection.
2nd step: connect the battery connections.
Operation
The electronic circuit board immediately begins operation once the battery is connected or the external
fuse is inserted. The display shows the current operating mode.
It is factory programmed for an 8 hours operation; to change the setting follow the instructions of PA
RC100 controller.
The 5 minutes On/Off delay has been set to avoid that the luminaires switch on/off if the panels are
temporarily illuminated/obscured
Protection functions
The following integrated protection functions of the electronic circuit board ensure that the battery is
handled as gently as possible.
These protection funcions are part of the basic function of the electronic circuit board:
• Overcharge protection
• Deep discharge protection
• Battery undervoltage protection
• Solar panel reverse current protection
The following installation faults do not destroy the circuit board. After having corrected the fault, the device
will continue to operate regularly:
• Protection from solar panel short circuits/incorrect solar panel polarity *
• Protection from short circuits at the luminaires output, or excessive luminaires current
• Protection from battery connection with incorrect polarity
• Protection from solar panel overcurrent
• Protection from luminaires overtemperature
• Protection from overvoltage at the luminaires output
*the reversal -polarity protection of the solar panel in a 24V system is only provided up to an open-circuit
voltage of 35V.
