Note:
After activating the emergency switch
-off, the
outputs of the UPS are de
-energised. Only after
acknowledgement/resetting of the emergency
switch
-off mechanism and manual restart by
switching the "UPS On
" does the UPS return to
normal
operating condition.
To install the emergency switch-off mechanism, proceed as
follows:
Check whether the UPS is switched off, and switch it 1.
off if necessary (standby operating mode).
Remove the plug part from the EPO
insert on the 2.
back of the UPS by loosening the two external
screws (see also Page 26, Item 10).
Connect a floating NC contact (loadability of at least 3.
60 V DC/30 V AC 20 mA) to the pins of the plug part.
For this purpose, use a flexible cable with a diameter 4.
of min. 0.5 mm
2
and max. 2.5 mm
2
. Reconnect the
plug and lock the insertion in the socket by tightening
the external screws.
The integrated emergency switch-off mechanism is
used solely to switch off the UPS power. This is
done electronically and does not correspond to an
EMERGENCY-STOP
device
as per DIN
EN
ISO
13850.
