High Voltage Prescaler
CAUTION!
1.
Installation of the Prescaler Option involves work with poten-
tially fatal voltages. NEVER work alone: Have at least one person
present who can render assistance and CPR in the event of an acci-
dent. If you have any doubt about your qualifications to work on a
high voltage system, DON'T DO IT!
2.
When working with any DC system, even so-called ungrounded
("floating") systems with no planned chassis connection, discon-
nect the negative battery terminal first.
