Checking hardware
All hardware must be checked at least once a year. Nautel recommends more frequent checking if the
VS300 is subjected to above average thermal cycling, caused by turning the VS300 on and off.
•
To prevent damaging the hardware, ensure that the proper size tools are used. In most cases,
hardware is metric.
•
A mounting surface or terminal that has changed colour indicates a loose hardware connec-
tion.
Battery replacement
The VS300's exciter/control PWB contains a battery backup circuit that allows the time and date to
update during ac power failure. The battery should be replaced every 12 months. See
