5.2. NETWORK APPLICATION
In this configuration, up to 10 units can be connected to a local network and to a computer, when
running CX-MON300 application.
Each unit must have an independent IP Address.
See Addendum A to find more regarding IP allocation.
The CX-MON300 application acts as a network server. The measurements result and alarms can be
visualized in a series of computers running CX-MON300Client application.
Figure 2 - Network typically application
5.3. CX-MON300 Monitoring Software
There are two free software applications delivered with any CX300 unit:
CX-MON300
CX-MON300Client
CX-MON300 Software is able to manage the measurements from up to 10 CX300 units. The
software is similar with a SCADA system and can be configured by the user.
Scheduled, On Alarm or On demand the measurements (including spectra) can be transferred to
any CXSpectra©database.
For more details, see CX-MON300 User Manual.
CX-MON300Client is simple software being a client for the CX-MON300.
Many client installations are allowed.

6. DEVICE INSTALLATION
The unit has been designed and manufactured in a way assuring a high level of user safety and
resistance to interference occurring in a typical industrial environment. In order to take full
advantage of these characteristics installation of the unit must be conducted correctly and
according to the local regulations.
Read the basic safety requirements prior to starting the installation.
Ensure that the power supply voltage corresponds to the nominal voltage (18 to 36 V
DC).
ALL INSTALLATION WORKS MUST BE CONDUCTED WITH A DISCONNECTED
POWER SUPPLY!!!
Protecting the power supply connections against unauthorized persons must be taken
into consideration.

6.1. UNPACKING
After removing the unit from the protective packaging, check for transportation damage.
Figure 4 - CX300 enclosure dimensions (in mm)
Any transportation damage must be immediately reported to the carrier. Also, write down the unit
serial number located on the housing and report the damage to the manufacturer.

CX300 MODULE –User manual
Doc.2016002

6.2. ASSEMBLY
The unit is designed for mounting inside housings (control panel, switchboard) insuring
appropriate protection against surges and interference. Metal housings must be
connected to ground in a way that complies with the governing regulations.
DISCONNECT THE POWER SUPPLY PRIOR TO STARTING ASSEMBLY.
Check the connections are wired correctly, prior to switching the unit on.
Caution
Installation should be conducted by qualified personnel. During installation, all
available safety requirements should be considered. The fitter is responsible for
executing the installation according to this manual, local safety and EMC regulations.
The unit is not equipped with an internal fuse or power supply circuit breaker.
Because of this, an external time-delay cutout fuse with a small nominal current value
must be used (recommended bipolar, max. 2A).
The diameter of power supply network cable must be selected somehow that in the
case of a short circuit of the cable from the side of the unit, the cable shall be
protected against destruction with an electrical installation fuse.
Wiring must meet the appropriate standards and local regulations and laws.
In order to secure against accidental short circuit, the connection cables must be
terminated with the appropriate insulated cable tips.
Tighten the clamping screws. The recommended tightening torque is 0.5 Nm.
Loose screws can cause fire or defective operation. Over tightening can lead to
damaging the connections inside the units and breaking the thread.
Unused terminals must not be used for connecting any connecting cables (e.g. as
bridges), because this can cause damage to the equipment or electric shock.
When the installation is completed, do not touch the unit’s connections when it is
switched on, because it carries the risk of electrical shock.
Due to possible significant interference in industrial installations, appropriate measures assuring
correct operation of the unit must be applied. To avoid the unit of improper indications keep
recommendations listed below.
Avoid running signal cables and transmission cables together with power supply cables and cables
controlling inductive loads (e.g. contactors). Such cables should cross at a right angle.
Contactor coils and inductive loads should be equipped with interference protection
systems, e.g. RC-type.
Use of screened signal cables is recommended. Signal cable screens should be connected to
the earth only at one of the ends of the screened cable.
In the case of magnetically induced interference, the use of twisted pair signal cables is
recommended. Twisted pair (best if shielded) must be used with 4 to 20 mA analogical
outputs.

In the case of measurement or control, signals are longer than 30m or go outside of the
building then additional safety circuits are required.
In the case of interference from the power supply side, the use of appropriate interference
filters is recommended. Bear in mind that the connection between the filter and the unit
should be as short as possible and the metal housing of the filter must be connected to the
earth with the largest possible surface. The cables connected to the filter output must not be
run with cables with interference (e.g. circuits controlling relays or contactors).
Connections of power supply voltage and measurement signals are executed using the screw
connections of the unit’s enclosure.

Do not apply any external voltage on these inputs!
A free relay contact or push-button must be used to activate the digital input.
NOTE 2: External speed sensor can be supplied at 12 or 24 V dc (max 100mA). The unit cover must
be removed, to have access to a jumper. The jumper position must be changed (for detail see
Chapter 7).
NOTE 3: These terminals are internally connected to the negative side of the power supply (24 V
dc). Because the power supply negative side is normally connected to an earth (shield) point,
these terminal can be also be considered a ground terminals. Signal cable screens should be
connected to the earth only at one of the ends of the screened cable. Leave unconnected if the
vibration screen is connected to the earth in another place.
Figure 6 - Typical external power supply wiring diagram.
NOTE 4: These inputs are used for temperature measurement using RTD type temperature sensors
(by 2- and 3-wire method). Only RTD's type PT100 can be used. In 2-wire method, connect
terminal "B" with "b.”
NOTE 5: These outputs have a common minus (-) terminal. Therefore, the terminals 35, 37, 39 and
41 are connected together.
NOTE 6: The power supply for an additional cooling fan is the unit main power (Terminals 1 and 2).
A thermal switch placed inside of the unit supplies the external fan when the inside temperature
increases more than 60ºC.
The unit cover must be removed to have access to these terminals.
