6.1.3 Emergency-off function (REPO)
The emergency-off function (REPO = Remote Emergency Power-
Off) serves to shut down the UPS system and to immediately switch
off the connected consumers remotely. The REPO connector (rear
side of the UPS system) must be removed and an external emer-
gency-off switch must be connected for this.
Connection cable cross-section = 0.32 - 4 mm
2
(AWG 22 - 12)
Recommended connection cable cross-section = 1.5 mm
2
(AWG 18)
CAUTION

The emergency-off switch may not be connected to circuits
that are connected with the mains power supply network.
A reinforced insulation to the mains is required. The emer-
gency-off switch must be dimensioned for at least 24 V and
20 mA. An opening contact must be used. For proper opera-
tion, the emergency-off function must remain active for at
least 250 ms

If the emergency-off function is activated, the input voltage of
the UPS system must additionally be disconnected
NOTE

Leave the REPO connector in the emergency-off connector
plugged into the UPS system if the emergency-off function is
not required

Always test the emergency-off function before a critical load
is connected. This will prevent an unintended load breaking
