The display module attached to the front panel can be detached easily by removing the two screws.
This allows the display module to act as a wired remote control. The interconnection cable between
the solar charger and the display module is a straight wired (1:1) 9 pole DSUB9 male to DSUB9
female cable. This is a standard serial communication cable that is widely available. The maximum
advised cable length is 10 meter.
The alarm relay will be triggered (C connects to NO) when a
battery under- or overvoltage limit has been exceeded. When the
battery voltage is in normal range, the relay contacts are in the
position as indicated on the left (C connects to NC). The relay
contact specifications are 10A @ 230Vac or 30Vdc.
