Emergency Measures; Danger Areas; Leakage Currents - Chloride 70-NET Bedienungsanleitung

SAFETY
• Data transmission lines should not be connected or disconnected during a thunder-
storm.
• Emergency Power Off (E.P.O.) connector is located on the rear of the unit (see fig. 7
on page 14). When this connection is open, the logic circuit will immediately shut
down the UPS output. In order that the wiring installation safety complies to the Euro-
pean Harmonized Document HD384-4-46 S1, an Emergency Switching Device
(E.S.D.) shall be fitted downstream of the UPS.
• For T and LAM versions only: Hazardous voltages are present on the transformers
mounted in the battery compartment at the base of the UPS as soon as the unit is
connected to the mains supply. This condition is independent of the operation of
switches QS1-4.
• Dedicated components, which remain live even with all UPS switches in "OFF" posi-
tion must be labelled accordingly.
• This device is not equipped with its own mains separation device. You are, therefore,
required to provide a mains separation device at the installation site.
• In order to guarantee safe working conditions, ensure all voltage sources are isolated
before carrying out the power connections. ENSURE CORRECT POLARITY!
• The separation device for the mains supply must bear a warning label on which the
following is stated: "Switch off the UPS supply prior to working on this system!"

1.4. EMERGENCY MEASURES

In order to conform to the European Standard EN62040-1-1 (par. 5.1.5) , a UPS must be
fitted with an Emergency Power Off device (E.P.O.) that can be used to shut down the unit
completely in the event of an emergency. 70-NET is equipped with a dedicated user input
which is default configured to execute the EPO function. Refer to "Emergency Power Off
(E.P.O.) - X8" on page 25 for instructions on how to install an E.P.O. button on this UPS.
In the event of an emergency, press the EPO button immediately in order to shut
down the entire system.
If, for any reason, the EPO fails to switch off the UPS, proceed as follows:
• Open the external mains separation device
• Switch off the load
• NEVER ATTEMPT TO OPEN OR CLOSE THE UPS BATTERY SWITCH UNDER
EMERGENCY CONDITIONS
• In case of fire, call the emergency personnel/fire brigade, who must put out any
flames using an extinguisher appropriate to the batteries in use
• NEVER ATTEMPT TO EXTINGUISH A FIRE USING WATER AS BATTERIES
CARRY LIVE VOLTAGE AT ALL TIMES

1.5. DANGER AREAS

When the UPS is closed, parts which carry voltage must not be touched. After removing the
external panels and/or terminal protection, terminals and rails, exposed metal parts and
other components carrying dangerous voltages are no longer protected against accidental
contact!
Danger
The UPS contains capacitors which continue to store energy for a period of time after the device
has been disconnected from the mains supply(ies) and battery. This voltage (> 400 V DC) is
present at the battery terminals. For this reason, check that the UPS and the external mains sep-
aration device are switched off and the battery fuses removed. Before continuing work, measure
the voltage at the battery terminals and at the mains input filter and wait until this has dropped to
0 V or wait at least 5 min. after disconnecting. Failure to do this can lead to severe electrical shock
and even death.

1.6. LEAKAGE CURRENTS

Danger
The PE safety conductor shall be connected before any other cables.
