1. Safety and EMC instructions
1.2 Operation
★ Do not disconnect the mains cable on the UPS or the building wiring socket (grounded
shockproof socket) during operation as this would remove the ground to the UPS and of all
connected loads.
★ The UPS output socket or output terminal block may be electrically lived even if the UPS
system is not connected to the building wiring terminal.
★ In order to fully disconnect the UPS, first press the Standby button, then disconnect the
mains lead.
★ Ensure that no liquid or other foreign objects can enter the UPS.
★ The UPS can be operated by any individuals with no previous experience.
1.3 Maintenance, servicing and faults
★ The UPS operates with hazardous voltages. Repairs may be carried out only by qualified
maintenance personnel.
★ Caution - risk of electric shock. Even after the unit is disconnected from the mains power
supply (building wiring socket), components inside the UPS are still connected to the battery
which are potentially dangerous.
★ Before carrying out any kind of service and/or maintenance, disconnect the batteries.
Verify that no current is present and no hazardous voltage exists in the capacitor or BUS
capacitor terminals.
★ Batteries must be replaced only by qualified personnel.
★ 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. Verify that no
voltage is present before servicing!
★ Batteries have a high short-circuit current and pose a risk of shock. Take all precautionary
measures specified below and any other measures necessary when working with batteries:
－ remove all jewellery, wristwatches, rings and other metal objects
－ use only tools with insulated grips and handles.
★ When changing batteries, replace with the same quantity and the same type of batteries.
★ Do not attempt to dispose of batteries by burning them. It could cause explosion.
★ Do not open or destroy batteries. effluent electrolyte can cause injury to the skin and eyes. It
may be toxic.
★ Please replace the fuse only by a fuse of the same type and of the same amperage in order
to avoid fire hazards.
★ Do not dismantle the UPS, except the qualified maintenance personnel.
