3.4.3 Measuring Line -to-Line Voltage
USE EXTREME CAUTION WHEN TROUBLESHOOTING DVS WITH
ANY PANEL REMOVED. ELECTRIC SHOCK CAN KILL: Touching live
electrical parts can cause fatal shocks or severe burns. The input power circuitry
and internal circuits are live whenever input power is on.
DANGER
Using extreme caution, measure voltages across K1.1/K1.2, K1.2/K1.3 and K1.1/K1.3 per
Figure 5. Confirm that all measurements conform to specifications in WCSI Doc. #08750-10.
If voltages are out of range, turn off power at utility power disconnect box, lock/tag utility
disconnect, and measure voltage between phases. If utility voltages do not conform to
specifications in WCSI Doc. #08750-10, contact facility electrician.
