Maintenance Level 1
This module provides maintenance advice on different hardware components of the OXO Connect
system.
7.1 Battery Maintenance
OXO Connect systems (except the OXO Connect Compact) are supplied with internal batteries that
provide back-up power in the event of a mains power failure. Alternatively, all systems may be
optionally equipped with an external battery pack to provide back-up power.
To guarantee system shutdown without data loss in the event of a mains power failure or if the mains
plug is unplugged from the wall socket, replace the batteries every two years. This maintenance
operation is vital to guarantee sufficient power autonomy to allow the files to be saved before the
system shuts down.
Before replacing batteries, the system must be powered down and the power cable removed from the
mains supply.
• To replace internal batteries, the rear panel of the system cabinet must be removed and the battery
drawer pulled out.
• To replace external batteries, the external battery box must be opened.
To maintain a good balance, replace all the batteries at the same time with batteries of the
same type, from the same manufacturer and from the same batch.
Make sure you respect the correct polarities when replacing batteries. There is a risk of
explosion if the batteries are incorrectly replaced. Used batteries must be disposed of
according to the battery manufacturer's instructions.
The batteries are supplied uncharged. File saving in the event of a power failure can only be
guaranteed once the batteries have been charged; that is, about 12 hours after turning on the system
(PowerCPU EE switch in ON position).
