9. Maintenance
!
Before any work on batteries (e.g substitution), open the
corresponding safety device (fuse). Always handle the battery with
care, avoiding contact between the connection cables or terminals and
other parts of the equipment.
Any work must be performed by qualified personnel, aware of the
danger of electrric shock and the precautions that should be taken.
In all cases appropriate tools must be used and these tools must be
isolated.
There are no components susceptible to being manipulated in rectifiers
or a control unit removing any of these modules carries the risk of
exposure to dangerously high voltages as well as invalidating the
guarantee -if it is current.
9.1. Preventative maintenance
9.1.1. Frequency of preventative maintenance inspections
With the aim of maintaining equipment in optimal operating conditions, annual inspection
is recommended. EN50171 requires at least one installation test during this period of
time.
9.1.2. Definition of the inspection
9.1.2.1. Battery check
• Measure the voltage of each element to ensure they are within margins.
• Ensure that the most recent tests (Functional tests and Duration tests) have given
correct results.
9.1.2.2. Visual inspection
• General condition of the equipment dents, rust (Remove rust), tightness of screws,
excessive temperature at any point (fuses, battery connections...), etc...
• Exterior condition of the batteries (warped trays, filtrations or leaks, electrolyte level
of open batteries, etc...)
9.1.2.3. Check connections
• Tightening of screws associated with alternating AC terminals
• Tightening of battery connections
• Tightening the output terminals.
• Tightening the auxiliary and power free contact terminals.
• General tightening of the screws.
! Use isolated tools and avoid short circuits
