2. Use a voltmeter to check the voltage at the terminal block on the power
supply. Connect the voltmeter's positive contact to the positive (+) terminal
on the CSS power supply terminal block. Connect the voltmeter's negative
contact to the negative (–) terminal on the CSS power supply terminal block.
If the power is wired correctly, the voltmeter registers approximately
+48VDC to +56VDC (or battery float voltage).
Do not allow the test probes of the voltmeter to touch each other while they are
touching the power terminals. This is an ENERGY HAZARD to you, to the
voltmeter, and to the wires connecting the CSS to its power source.
