DC Connection
The DC version of the KISS 4U platform is equipped with a +24V DC PSU (with
three screw terminals and without an ON/OFF power switch).
The KISS 4U (DC version) is designed without a disconnecting
device!
In order to reduce injuries and damage by hazardous voltages (risk
to injury by direct or indirect contact with electrical energized bare
parts of the DC screw terminals) the following measures should be
adopted:
❏
The KISS 4U system should be mounted and installed into a
SERVICE ACCESS AREA
or
into a
RESTRICTED
ACCESS
LOCATION].
❏
It must be ensured that the system can be powered ON and
OFF via a readily accessible two-pole disconnect device that
shall be incorporated in the building installation wiring (e.g.
overload protection switch).
❏
Users which are admitted to the
SERVICE ACCESS AREA
or to
the
RESTRICTED
ACCESS LOCATION must
be suitably
instructed and sufficiently informed about the associated
dangers.

1.
Ensure that the system is disconnected from the DC mains by the disconnect
device.
2.

end of the power cord [Minimum cross section: 1.25 mm

(16 AWG)]. Make
sure that you have the right polarity of the connection.
3.
Fasten the screws to secure the DC power cord into the DC terminal.
