CAUTION
•
The emergency power off switch must not be connected to
circuits which are connected to the supply network. Reinforced
insulation from the network is required. The emergency power
off switch must be designed for at least 60V DC / 30V AC and
20mA.
•
Depending on the programming via the UPS menu (see Chap-
ter 4.3), either an opener or a closer can be used. The emer-
gency power off function must be active for at least 250ms for
proper operation.
•
If the emergency power off function is activated, the input volt-
age of the UPS system also needs to be interrupted.
•
The emergency power off function is only used to shut down
the UPS voltage on an electronic basis.
PLEASE NOTE
•
Leave the plug of the UPS system connected if you do not
need the emergency power off function.
•
Always test the emergency power off function before connect-
ing a critical load. This avoids the load being switched off ac-
cidentally

5.4 Surge voltage protection for data and telephone
lines (DSL / telephone / fax / network)

cables. This involves connecting the incoming cable to the IN connec-
tion on the reverse of the UPS system. Connect the OUT connection
