WARNING
High voltages are present at capacitor box. Whenever possible, keep one hand away
from the equipment to reduce the hazard of current flowing through vital organs of the

follow this warning can result in personal injury or death.
Capacitors are electrical storage devices that are designed to hold a charge after
power is disconnected from them. For this reason, extreme care must be taken when
working on or around capacitors. Discharge capacitors with a shorting plug before
performing maintenance on capacitors. Failure to comply with this warning can result
in severe electrical shock resulting in serious injury or death.
