Operation; Maintenance, Servicing And Faults - INFOSEC UPS SYSTEM E4 Value+ Manuel Utilisateur

1-4. Operation

⚫
Do not disconnect the mains cable on the UPS system or the mains outlet
(shockproof power outlet) during operations since this would cancel the protective
earthing of the UPS system and of all connected loads.
⚫
The UPS system has its own, internal current source (batteries). The UPS outlets or
terminal block may be electrically live even if the UPS system is not connected to the
mains outlet.
⚫
In order to fully disconnect the UPS system, first press the OFF/Enter button to
disconnect the mains.
⚫
Prevent any fluids or other foreign objects from entering the UPS system.

1-5. Maintenance, servicing and faults

⚫
The UPS system operates with hazardous voltages. Repairs may only be carried out
by qualified maintenance personnel.
Caution - Risk of electric shock. Even after the unit is disconnected from the mains
(mains outlet) components inside the UPS system are still connected to the battery
and electrically live and dangerous.
⚫
Before carrying out any servicing and/or maintenance disconnect the batteries and
check that there is no current or hazardous voltage in the high capability capacitor
terminals such as BUS-capacitors.
⚫ Only people who are familiar with batteries and with the required precautionary
measures may replace the batteries and supervise operations. Unauthorized
persons must be kept well away from the batteries.
Caution - Risk of electric shock. The battery circuit is not isolated from the input
voltage. Hazardous voltages may occur between the battery terminals and the
ground. Before touching, please check that no voltage is present!
⚫
Only replace the fuse with the same type and amperage in order to avoid fire
hazards.
⚫
Do not dismantle the UPS system.
