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.

Use a Prescaler if system voltage EVER exceeds 50 V! Then set voltage scaling with F13 (see page 50).
