Power Supplies and Fuses
In standard configuration, the AC power socket on the side of the locker room clock
serves as the point of entry for power. In the concealed wiring configuration, AC power
enters through the cutouts on the back of the clock cabinet. In this case, the installer
brings the power cable to a terminal block, accessible by removing the digit assembly
from the front of the cabinet. From the power terminal block, or from the back of the AC
socket, the line side of AC passes through a 5-amp fuse on the way to the Mean Well
RSP-320-24 power supply module. This is an AG style fuse, which should only be
replaced with a fuse of the same style and rating.
Power connections are made along a row of screw terminals on one side of the power
supply module. The Mean Well RSP-320-24 module in the cabinet provides 18.9 VDC
to the illuminated digits and driver. If you replace a power supply module, check the
output voltage to make certain it is set to 18.9 VDC.
