maintenance and servicing
Preventative maintenance for the Comet is limited to the strict minimum.
However, the list below indicates important procedures to ensure continuous and
correct operation.
Danger: high voltages are present in the Comet system. Any servicing requiring
removal of the protection covers may be undertaken only by qualified personnel
certified by MGE UPS SYSTEMS.
■ check the installation and operating conditions:
■ ■ distance from wall,
■ ■ ventilation inlet and outlet vents free,
■ ■ operating temperature, particularly for the batteries;
■ no faults signalled by the lights.
Consult the after-sales support department for further information concerning the
services presented below requiring special tools, in particular the "Soft Tunor"
software.
Battery status is monitored by Comet. When the orange "operation on battery"
light 20 flashes and fault number "12" is indicated on the diagnostics display 27,
the battery should be checked.
When the red "load not protected" light 18 flashes and fault number "15" is
indicated on the diagnostics display 27 , a battery fault is present.
To clear these alarms, press the "security" 26 and "fault reset" 25 buttons at
the same time.
Caution: clearing the alarms in this way disables the battery monitoring and
backup time calculation functions (Monitor Plus option); contact the after-
sales support department to check the condition of the battery and replace
it if necessary. The after-sales support technician will reactivate the battery
monitoring and backup time calculation functions.
The battery cells contain substances which are dangerous for the environment.
Following replacement, the after-sales support department forwards old batteries
to special organizations for recycling and disposal.
