Installation
Danger!
The assembly and installation may be
performed only by trained specialists.
6.1 Safety and Other Notes
−
The Rittal CMC-TC system may be operated only
with connected protective earth conductor. The
protective earth conductor connection is made by
plugging in the IEC connection cable. This re-
quires that the IEC connection cable at the power
supply side be connected with the protective
earth conductor.
−
The electrical connection voltage and frequency
must conform to the rated values specified at the
rear of the housing and in the technical specifica-
tions (see page 19).
−
Before commencing work on the Rittal CMC-TC
system, it must be disconnected from the mains
power supply and protected against being re-
connected.
−
Protect the connection cables using cable ties on
the used housing or enclosure.
−
To prevent unnecessary cable losses, the used
cable lengths must not exceed the lengths speci-
fied in the technical specifications (see Chapter
14, page 19).

Power supply connection
You must connect the CMC-TC Wireless I/O-Unit to
the CMC-TC Processing Unit using the RJ45 con-
nection cable mentioned in Section 4.5.1 "Required
Accessories".
•
Insert the plug connector of the RJ45 connection
cable in the socket, as shown above, of the CMC-
TC Wireless I/O-Unit.

•
Insert the other end of the RJ45 connection cable
in a free RJ45 socket with number 1 to 4 of the
CMC-TC Processing Unit.
After connection to the power supply, the Status
LED of the CMC-TC Wireless I/O-Unit flashes auto-
matically. As soon as it is connected, the Status
LED illuminates alternately red, yellow and green.
6.3 Antenna Adjustment
The antenna of the I/O-Unit should always be ad-
justed parallel to the antennas of the sensors. If all
sensors are aligned vertical, the I/O-Unit antenna
must be also aligned vertical.
Warning!
FCC certification is valid only for the
2.4 GHz omnidirectional antenna
model IW-144 having a maximum 2 dBi
gain. An antenna having the same
specifications as model IW-144 but
with a gain of less than 2 dBi is an ac-
ceptable substitute.
