Always assume that all circuits are under voltage until they are completely
disconnected, subjected to tests and labelled.
Disconnect all of the power supply prior to working on the device.
Always use a suitable voltage detection device to check that the supply is interrupted.
Pay attention to any dangers and carefully check the work area ensuring that no instruments or foreign
objects have been left inside the compartment in which the device is housed.
The correct use of this device depends on a correct manipulation, installation and use.
Failure to adhere to the basic installation information can lead to injuries as well
as damage to the electric instruments or to any other product.

Disposal
Defective devices must be disposed of as special waste at the appropriate collection
points set up for this purpose. National or regional regulations on the disposal of special
waste must be followed.
Service and maintenance
The device undergoes several safety assessments before shipment and will be sealed. If
a device is opened, the safety assessments have to be repeated. A warranty will be provided
for unopened devices only.
Use a dry cloth.
Installation to mains
Installation of CMS-700 to mains shall include a switch or circuit breaker for the connection
to mains. The switch or circuit breaker must be suitably located and easily reachable and must be

Product overview
Intended use
The system consists of a control unit and sensors with different measurement ranges.
The sensors measure alternating, direct and mixed currents (TRMS) and get connected to the control
unit by a flat cable, the CMS-Bus. The measurement data can be displayed or analyzed via LAN interface
with the integrated web server or Modbus TCP or SNMP protocols or via RS485 interface, such as
Modbus RTU.
The CMS-700 control unit is a measuring instrument for recording
the performance and energy of mains and of up to 96 branch sensors.

Principle of measurement
The principle of measurement for AC of the CMS-700 control unit includes measurement on the
mains and branches. On the mains side, all values are measured directly. On the branches, current is
measured while voltage, power factor as well as active power and energy are calculated using
measured mains values.
For further information, please refer to the following table
Mains Branches/Sensors

Attention: Referring to the
diagram in the figure aside,
please note that N on the
supply has to be connected
in order to avoid damage
of the device. Twisting

Events
If a measurement object (e.g. TRMS current of a branch) crosses predefined threshold conditions
(value, direction and delay time) then an event is registered.
Following options linked to events logging are available:
• Visualization of all detected events in WebUi
• Reading event/alarm status through Modbus register
• Export via FTP and Email
In order to configure an event, specifications of the following are required:
• The threshold value
• Indication of cross direction (cross up, cross down)
• Indication of delay time
Events can be linked both to mains and branches object values:

Object Unit Alarm cross Resolution Format
Status up/down Threshold

The type of event is available on Modbus map as Alarm Status. Resolution refers to the accuracy with
which the value is defined. If several events occur for the same main or branch, the newest one will be
given out via Modbus.
Three register blocks are available in the Modbus register map:
• only object type with alarm code
• object type with alarm code and threshold value
• number of currently active alarms

are stored in the following memory areas:
Stored values
Mains
• Voltage [V]: L1, L2, L3
• Current [A]: L1, L2, L3, N
• Power factor [-]: L1,L2,L3
• THD U [%]: L1, L2, L3
• THD I [%]: L1, L2, L3, N
• Active power[W]: L1, L2, L3
• Apparent power [VA]: L1, L2, L3
• Reactive power [VAR]: L1, L2, L3
• Active power summation [W]
• Apparent power summation [VA]
• Reactive power summation [VAR]
• Active energy [Wh]: L1, L2, L3
• Apparent energy [VAh]: L1, L2, L3
Branches
• Current (TRMS, AC, DC) [A]
• Active power [W]
• Active energy [Wh]
These values of the respective stacks can be exported as a CSV-file
and pulled into an FTP or sent by e-mail.
Time reference
The measured values are provided with a UTC time stamp. UTC (Universal Coordinated Time)
stands for the location-independent world time in seconds.
