Case 2
If the TPSU16 power supply AC and DC LEDs light, but the system does not operate, the
TPSU16 DC output overcurrent circuit breaker may have opened because of a DC short
circuit.
To reset the DC output overcurrent circuit breaker
1. Turn the DC power switch OFF for 15 seconds and then turn it back on. The system will
go back to normal operation if the overcurrent breaker resets.
2. If the system continues to fail, press in the two -24 volt circuit breakers located on the
bottom left corner of the TPSU16 power supply.
If, then, the system does not return to normal operation, the TPSU16 power supply may
be defective or an optional PCB may be shorting out the TPSU16.
3. Remove all optional PCBs and the Expansion KSU to locate the short, then repeat Steps
1 and 2 and perform the power supply test.
4. If the power supply fails the test, replace the power supply

Mounting the Base KSU

WARNING!

location of the four screw holes (there is one on each corner).
Make sure the location of the Base KSU meets the minimum clearance requirements
specified in
Note
2. Drill holes on these marks.
If mounting the KSU directly to a wall, align screws with studs behind the wall. If using
a hard board between the KSU and the wall, install screws first to the hard board, and
then secure the hard board to the wall, making certain that screws are aligned with studs.
3. Secure screws approximately two thirds of the way into the top two holes on the
mounting surface.
4. Hang the unit from the top two screws and then secure the screws completely into the
mounting surface.
5. Finish securing the unit to the mounting surface by completely screwing the bottom two
screws into the wall.
