7.2 Maintenance & Inspection
This section describes the basic periodic maintenance and inspection
procedures for the Electronic bypass.
Caution! To prevent electrical shock and damage, disconnect all power
before servicing the Electronic bypass package. Then wait at least ten
(10) minutes after the power supply is disconnected and all LEDs are
extinguished.
The Electronic bypass will function longer if kept clean, cool and dry, and if all
precautions highlighted in this manual are observed. Periodically inspect the
Electronic bypass package as described in the table below to prevent
accidents and to ensure high performance with high reliability.
