WARNING!
To avoid personal injury or equipment damage, only qualified personnel should
perform the procedures in this manual.
CAUTION
Versions of BESTCOMS with version numbers below 1.31.00 are incompatible
with newer versions of BE1-851 firmware. If your relay contains version 2.42
firmware or higher (most relays made after August 1999), you MUST upgrade
to BESTCOMS version 1.31.00 or higher (version 2.00.00 and higher
recommended) before connecting to the relay. Failure to upgrade BESTCOMS
prior to connections will result in database corruption of all stored data in
earlier versions of BESTCOMS.
NOTE
Be sure that the relay is hard-wired to earth ground with no smaller than 12
AWG copper wire attached to the ground terminal on the rear of the unit case.
When the relay is configured in a system with other devices, it is
recommended to use a separate lead to the ground bus from each unit.
