CAPACITOR CHARGE LIGHTS
Observe both capacitor charge lights (CCL1, CCL2).
CCL1 is on the outside of the contactor box. CCL2 is
on the switch panel inside the low voltage area. The
lights will stay illuminated as long as the voltage on
the DC link is greater than 50 VDC. Refer to Figure
20-8.
Hazardous voltages may be present in this equip-
ment even if the engine and capacitor charge
lights are off.
Use measurement and protective equipment
rated for 2000 VDC minimum to verify that no
voltage is present before touching any terminal.
