2 Safety information
2.1 General
The safety instructions are intended to protect people and property from damage and hazards
that could arise as the result of improper use, incorrect operation or other misuse or devices,
especially in explosive areas. Therefore, please read the operating instructions carefully before
working on the product or operating it. The operating instructions must be accessible to operat-
ing personnel at all times.
Please make sure that all documents are present and complete before commissioning or per-
forming other work on the product. If the documents have not all been delivered in full or if fur-
ther copies are necessary, they can also be obtained in other languages.
The product is built according to the latest state of the art. However, hazards to people, machin-
ery and systems can still arise as the result of improper handling, unintended use or operation
and maintenance by persons inadequately trained on the product.

operator’s plant must read and understand the operating instructions.
The product may only be assembled, disassembled, installed and repaired by instructed, suffi-
ciently trained and authorised personnel.

8 Transfer of liability when operating in potentially explosive atmospheres
The owner of the system is exclusively liable for the appropriate configuration of the electrical
connections with respect to explosion protection regulations and correct commissioning.
If the system is installed by a sub-contractor on behalf of the owner, the system may only be
commissioned after the sub-contractor has issued written confirmation in the form of a certificate
of installation that the system has been installed correctly and professionally in accordance with
the applicable legal regulations.
The operator is obliged to notify the responsible authorities of the initial commissioning of explo-
sion-protected systems or system components and their re-commissioning following extensive
changes or maintenance.

10.2 HE103.03 cULus Hazloc DIV2
The version for DIV2 may not be operated without the safety clip to guard against acci-
dental disconnection of the plug connection! If operated in a potentially explosive at-
mosphere, there is otherwise an explosion hazard, due to spark formation!
For use in DIV2, the supply voltage may not exceed 28.1 V DC. This must be ensured
through the use of an appropriate power supply unit.
Attaching the safety clip
1. Insert the connecting cable socket into the M12 connector as far as it will go (mind the
position of the code cam).
2. Tighten the knurled rotating ring of the socket by hand.
3. Attach the safety clip to guard against accidental disconnection of the plug connection.
- Place both shell halves of the clip around the plug connection.
- Press both shell halves firmly together with your hands until the lock snaps into place.
- Place the arrow connected to the two shell halves around the cable and pull it through
the eyelet at the other end so that the notice "DO NOT DISCONNECT UNDER
VOLTAGE" can be read alongside the cable.

Attaching the protection cap
After disconnecting the plug, the protection cap must be attached to the M12 plug!
Detach the safety clip and attach the protection cap.
1. Disconnect voltage.
2. Pry apart both shell halves of the sleeve with a screwdriver.
3. Close off the M12 plug well with the protection cap.

11.3 Operating range of the vibration monitoring unit
The operating range is independent from the measuring range. It can be derived from the maxi-
mum acceleration, which is 16.5 g across all frequencies. The maximum measurable vibration
velocity is based on the formula
 
For sinusoidal vibration,  
 applies
Fig. 5: shows the operating range of the vibration monitoring unit, which is limited by the maxi-
mum measurable vibration velocity in mm/s depending on the frequency in Hz.

The system operates according to the two-wire principle,
i.e. the entire function (voltage supply and current signal) is achieved using 2
wires (Pin 1 and Pin 3).
To avoid capacitive interference, pins 2 and 4 must remain open/unoccupied.

13 Assembly and disassembly
13.1 General notes
Assembly and disassembly work on and with the vibration monitoring unit may only be perfor-
med by an authorised specialist familiar with the safety regulations governing handling electrical
components!
The housing of the vibration monitoring unit must be earthed via the fixing –
through the machine earth of the mounting surface or through a separate pro-
tective conductor (PE)!
13.2 Fixing the vibration monitoring unit to the mounting surface
13.2.1 Prerequisites
• Mounting surface is clean and flat, i.e. free of paint, rust, etc.
• Measuring head area of the vibration monitoring unit must lie flat on the mounting surface.
13.2.2 Tool
•Hex key, width A/F 24
13.2.3 Work steps and instructions
•Screw vibration monitoring unit into the threaded hole of the mounting surface in a fric-
tion-locked manner using a hex key. The tightening torque should be 8 Nm.
•The tightening torque of the M12 union nut of the plug connection must not exceed 0.4
Nm.
To obtain precise measurement values, the vibration monitoring unit must be
fixed to the mounting surface in a friction-locked manner!
Auxiliary structures for fixing are to be avoided! If unavoidable, make them as
firm as possible!
Earth/ground loops are amongst the most common problems in measurement
set-ups with sensitive sensor technology. These issues arise due to unintentio-
nal differences in potential in the electrical circuit between the sensor and eva-
luation unit. As a countermeasure, we recommend our standard earthing con-
cept or, depending on the application, our Alternative earthing concept
Ensure that the earth connection is electrically secure.

HAUBER-Elektronik GmbH

14 Installation and commissioning
14.1 General notes
Installation and commissioning of the vibration monitoring unit must be performed by an
authorised specialist who is familiar with the safety regulations when handling
electrical components.
Protect the connection cable and any extension cable from electrical interfer-
ence and mechanical damage! Local regulations and instructions must be ob-
served in doing so!
14.2 Wiring diagram
Earth/ground loops are amongst the most common problems in measurement set-ups with
sensitive sensor technology. These issues arise due to unintentional differences in potential in
the electrical circuit between the sensor and evaluation unit.
Ensure that the earth connection is electrically secure.
14.2.1 Standard earthing concept
With the standard earthing concept, the sensor cable shield has no connection to the sensor
housing. The sensor housing has the same potential as the machine earth.

14.2.2 Alternative earthing concept
With the alternative earthing concept, the sensor cable shield has a connection to the sensor
housing. The sensor housing uncoupled from the machine earth by means of an EMC adapter
(red). With the alternative earthing concept an electrically secure earth connection is only en-
sured for versions with an M12 connector. For variants with an integrated cable, the alternative
earthing concept cannot be used.

In your request, please notify us if you would like to use the alternative earthing
concept. We will then provide you with the appropriate sensor cable and the
EMC adapter.
