Maintenance 

 

 

 

The  uninterruptible  power  supply  is  designed  and  produced  to  last  a  long  time  even  in  the  most  severe 
service  conditions.  It  should  be  remembered  however  that  this  is  electrical  power  equipment,  which 
requires  periodic  controls. Moreover,  some  components  have  a  limited  lifespan  and  as  such  must  be 
periodically checked and replaced should conditions so dictate: in particular the batteries, the fans and in 
some cases the electrolytic condensers. It is therefore recommended to implement a preventive maintenance 
programme, which should be entrusted to specialized personnel authorized by the manufacturers. 
Our  Technical  Support  Service  will  be  happy  to  recommend  the  various  personalized  options  for 
preventive maintenance. 

 

Periodic operations  (to be carried out by trained personnel and with doors closed) 

The following operations (which must be done with the doors closed) should be carried out  periodically (e.g. once a 
month, or more frequently in particularly difficult environmental conditions): 
 

-

 

Ensure that the air intake slots (located on the front door and at the back of the cabinet) and 
the output grilles located on the top of the cabinet are clean; 

-

 

Ensure that the UPS is working properly (the message “NORMAL OPERATION” will appear 
on  the  display  panel).  If  an  alarm  message  is  displayed,  check  the  meaning  in  the  manual 
before contacting the technical support service; 

-

 

Perform a battery test with the display panel. 

 

Maintenance inside the UPS (trained personnel only) 

 

 

 

Maintenance inside the UPS may only be carried out by trained personnel. 

High voltage is present inside the UPS even when the power supply and the battery have been 

disconnected

 

 
 

 

 

An electronic board contains lithium cell, this card and all the other card  must be replace  only by trained 

personel. 

 

After  disconnecting  the  power  supply  line  and  the  battery  cabinet,  the  trained  personnel  must  wait  around  ten 
minutes for the capacitors to discharge before working on the inside of the equipment. 
 

Ordinary maintenance for batteries (trained personnel only) 

The  system  automatically  controls  the  efficiency  of  the  batteries  every  24  hours,  and  sounds  an  alarm  when  the 
efficiency is lower than that calculated according to the stored capacity value. 
The lifespan of the batteries is linked to the operating temperature and to the number of charge and discharge cycles 
effected.  
The  capacity  is  not  constant,  but  increases  after  some  charge  and  discharge  cycles;  it  then  remains  constant  for 
several hundreds of cycles before decreasing permanently. 
Preventive maintenance of the battery entails: 

-

 

keeping the operating temperature within the field 20 - 25°C; 

-

 

performing two or three discharge and charge cycles during the first month of use; 

-

 

carrying out this operation every six months after the first month of use. 

Since the batteries are a source of energy, opening the battery disconnector does not eliminate the voltage inside the 
batteries.  DO  NOT  TRY  TO  ACCESS  THE  INSIDE  OF  THE  BATTERY  CABINET.  THERE  ARE  ALWAYS 
DANGEROUS VOLTAGES AROUND THE  BATTERIES.  If the batteries are thought to be faulty in any way, 
please contact the technical support service. 

 

 

 

If  the batteries need to be replaced, this must be done by a 

specialized technician

. The replaced parts must 

be  sent  to  a  specialized  company  for  disposal  by  means  of  recycling.  Batteries  are  classified  by  law  as 
“toxic waste”.
