8. Switch on each circuit breaker that services each DC circuit.
9. To check the DC power connection, see the following section.
Checking the DC Power Connection (CSS 11503 and CSS 11506)
Follow these steps to verify that you have correctly connected DC power to the
CSS 11503 or CSS 11506 chassis:
1. Turn on power to the DC circuit or circuits.
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).
Warning
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.
3. To power on and boot the CSS, refer to Chapter 3, Booting and Configuring
the CSS.
