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
accident. 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, disconnect
the negative battery terminal first.
