5.1 General 
 
The UPS is virtually maintenance free: take care of proper environmental conditions and keep air inlets-
outlets free of dust. Please read 2.1. 
 
 
5.2 Fuses 
 
If the AC input fuse (1) is defective, be sure it is replaced by a compatible fuse from the same make and 
type. Fuse ratings: see chapter 7. 
 
 
5.3 Batteries 
 
5.3.1 General 
The service life of the battery is up to 6 years. 
As a healthy battery is critical to the UPS, keypad 'ON' allows a battery test (3.2.2). When the condition of 
the battery is critical, a 'replace battery' alarm will be given (see 3.3). Charge the batteries for at least 10 
hours, switch the UPS off and back on, and perform a self test. If the alarm persists replace the batteries 
as soon as possible. 
 
5.3.2  Battery replacement  
  Warning: first read the safety rules in section 1.2. 
  When replacing the batteries, use the same number and voltage(V)/capacity(Ah). 
  Proper disposal or recycling of the batteries is required. Refer to your local codes for disposal 
requirements. 
  Never dispose of batteries in a fire: they may explode. 
  Do not open or mutilate batteries: their contents (electrolyte) may be extremely toxic. If exposed to 
electrolyte, wash immediately with plenty of water. 
  Avoid charging in a sealed container. 
  Never short circuit batteries. When working with batteries, remove watches, rings or other metal 
objects, and only use insulated tools.
