ConstruCtion, layout & Controls
General
SCC-30AB is designed for flush mounting on a wall / panel. The controls and
indications are built on the Front Panel face plate that has 4 countersunk holes
for flush mounting (Fig. 5.1). All the electronics, DIP switches for settings, terminal
strip for connections for the PV Array and the Battery and terminal for the optional
Battery Temperature Sensor (BTS) are mounted on a PCB that is in turn mounted
at the back of the face plate (Fig. 5.2). For flush mounting on the wall / panel, a
suitable cutout is required to be made in the wall / panel to accommodate the PCB
at the back of the unit. As the components at the back of the unit will be hidden
and protected behind the wall / panel, the components at the back of the unit are
exposed and do not have a protective cover. PLEASE HANDLE THE UNIT CAREFULLy
TO PREVENT ANy DAMAGE TO THE EXPOSED COMPONENTS AT THE BACk OF THE
UNIT.
NOTE: As the unit will be connected to 12V / 24V Nominal Solar Array / battery
system, there is no likelihood of electrical shock.
