Preventive Maintenance:
9.1.1
BBS Module Maintenance:
•
The BBS module was designed to be maintenance-free. There are no serviceable parts inside the unit.
•
Clean the cover of the BBS as needed using a damp cloth or nonabrasive cleanser.
Do not use ACETONE-BASE cleaning solutions. Keep cleaning solutions out of the
electrical receptacles on this device.
9.1.2
Battery Maintenance:
•
The BBS uses sealed maintenance-free batteries. Proper charging and limited cycling along with a
proper battery environment will ensure a long battery life.
Servicing of batteries should be performed or supervised by authorized personnel at least
four times a year.
A battery can present a risk of electrical shock and high short circuit current.
•
Before proceeding with maintenance, review battery system drawings.
•
Clean and tighten battery connections.
•
Replace batteries when conductance tests indicate 30% to 40% deterioration from the original value.
Use a battery conductance tester to create a log of the health of your batteries.
•
When replacing batteries, use the same model number and type batteries. Batteries should be replaced
in complete sets.
