MountIng
CMe3000 is mounted on a DIN-rail. The metallic clip on the
bottom is used to attach and deatach the device from the
rail. For safety reasons, a DIN-rail enclosure must cover the
terminals.
Power suPPly
Screw terminal (10) and (11) are used to supply the device
with power. The main supply voltage should be in the range of
100-240 VAC with a frequency of 50/60 Hz. The power needs
to be connected via a clearly marked and easily accessable
switch to make sure the device can be switched of during
service work. The switch must comply with IEC 60947-1 and
IEC 60947-3.
IMPortAnt
•
The installation must be performed by a qualified
electrician or another professional with the required
knowledge.
•
The power supply must be protected with a 10 A circuit
breaker of characteristics C or slow blow fuse.
ethernet connectIon
Connect a TP cable to the Ethernet RJ45 connector (4).
On successful connection, the yellow LINK LED (8) will be
permanently on.
All equipment connected to the Ethernet RJ 45 connector
must have double or reinforced insulation from mains to
prevent the risk of electric shocks.
M-Bus 2-wIre
M-Bus is a multi-drop 2-wire bus with no polarity. CMe3000
can drive up to 8 M-Bus unit loads (1 lunit load=1.5 mA). The
number can be extended by using an M-Bus Master from the
Elvaco CMeX10-13S Series.
Use a telephone cable (e.g. EKKX 2x2x0.5 mm) or standard
mains type (1.5 mm
2
) to connect meters to the M-Bus
connector (3). Do not exceed the maximum cable length of
1000 m.
All equipment connected to the M-Bus must have double or
reinforced insulation from mains to prevent the risk of electric
shocks.
FActory reset
There are two different ways to reset the CMe3000 to factory
default settings.
•
Reset the product and use dynamic IP settings.
Press and hold the push button (2) during start-up. Keep
it pressed for 5 seconds until the ACT LED (9) begins
to flash faster. Release the push button to perform
the factory reset. After a restart, the product will be
assigned an IP address from an available DHCP server.
•
Reset the product and use static IP settings.
Press
and hold the push button (2) during start-up. Keep it
pressed for 10 seconds until the ACT LED (9) begins
to flash faster for a second time. Release the button to
perform the factory reset. After a restart, the product
will use the following IP settings:
IP address: 192.168.0.10
Netmask: 255.255.255.0
Gateway: 192.168.0.1
CMe3000 can also be reset via the System page in its
integrated web interface. Through this menu, product reboots
and software updates may also be performed.
logIn
CMe3000 is configured via its integrated web interface. Type
the IP address of the product in the address field of a web
browser. Log in using the following credentials:
Username: admin
Password: admin
IP settIngs
CMe3000 supports both static and dynamic IP settings. To

Ir InterFAce
The IR interface can be used with an ABB electricity meter or
a product from the Elvaco CMeX Series. Remove the IR shield
(5) and mount the CMe3000 right next to the other device
with no space between the two. Do not remove the shield
unless planning to use the IR interface.
