2.9 Activating the Battery Cabinet(s) (continued)
2.9.1 Battery Cabinet #1 (continued)
6. Using a dc voltmeter, carefully measure the dc voltage at the top of the
battery disconnect circuit breaker. The voltage should be slightly above the
nominal battery voltage (for example: 380 volts dc for a nominal 360 volt battery
cabinet; 230 volts for a nominal 216 vdc). Record the voltage. The polarity should
have the positive on the left-hand pole (Phase A) and the negative on the right-
hand pole (Phase C) when you are facing the battery disconnect circuit breaker.
Verify that the polarity is correct. If it is not, locate and correct the problem.
7. When the polarity is correct, disconnect the top right-hand tray
connection to the tray immediately below. Verify there is no voltage present
between the left and right poles at the top of the battery disconnect circuit breaker.
2.9.2 Battery Cabinet #2
8. Open the front doors of Battery Cabinet #2 (the one next to Battery
Cabinet #1). Connect the battery trays in the cabinet to each other as shown in
Figure 2-3. The two connectors to be attached at each tray are similarly numbered.
9. Using a dc voltmeter, carefully measure the dc voltage at the top of the
battery disconnect circuit breaker in Battery Cabinet #1. The voltage should be
slightly above the nominal battery voltage (for example: 380 volts dc for a nominal
360 volt battery cabinet; 230 volts for a nominal 216 vdc). Record the voltage. The
polarity should have the positive on the left-hand pole (Phase A) and the negative
on the right-hand pole (Phase C) when you are facing the battery disconnect circuit
breaker. Verify that the polarity is correct. If it is not, locate and correct the
problem.
10.When the polarity is correct, disconnect the top right-hand tray connec-
tion to the tray immediately below in Battery Cabinet #2. Verify there is no voltage
present between the left and right poles at the top of the battery disconnect circuit
breaker.
