2.3 Skilled personnel
are persons who are familiar with the set-up, installation, commissioning and operation of the product and have ap-
propriate qualification for their work. For example:
•Training or instruction and/or authorisation to activate, deactivate, disconnect, ground and identify power circuits
and devices/systems in accordance with the standards of safety engineering.
•Training or instruction in accordance with the standard of safety technology for care and use of suitable safety
equipment.
•Knowledge about the installation of devices in explosion-prone areas.
2.4 Safety guidelines
This device has been designed and tested in accordance with the safety regulations for electron-
ic devices. However, its trouble-free operation and reliability cannot be guaranteed unless the
standard safety measures and special safety advises given in this manual will be adhered to
when using the device.
1.
Requirements of Directive 2014/34/EU (ATEX) and IECex must be observed
The respective national regulations for Ex use must also be complied with (e.g. EN
60079-11).
2.
Sensor can only be used with a GMH 3111 - ex, GMH 3151 - ex or GMH 3156 - ex!
Usage of other devices may result in destruction of sensor and device.
3.
Only use approved connection cable with max. 1 approved extension cable for the con-
nection of sensor to the handheld device.
4.
Please note the safety requirements of the handheld device !!
5.
When using a GMH 3156-ex with 2 stainless steel sensors, take care that the sensors
are not screwed in or have contact to surfaces with different electrical potentials.
6.
Potential equalisation:
All components (pressure sensor, power supply unit, interface, etc.) connected to
the device must be on the same potentials! If this is not guaranteed, you have to
connect them for a potential equalisation.
7.
Trouble-free operation and reliability of the device can only be guaranteed if the device is
not subjected to any other climatic conditions than those stated under "Specification".
8.
If the device is transported from a cold to a warm environment condensation may result
in a failure of the device.
In such a case make sure the device temperature has adjusted to the ambient tempera-
ture before trying a new start-up.
9.
If there is a risk whatsoever involved in running it, the device has to be switched off im-
mediately and to be marked accordingly to avoid re-starting.
Operator safety may be at risk if:
- there is visible damage to the device.
- the device is not working as specified.
- the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or maintenance.
10.
Warning: Do not use this product as safety or emergency stop device or in any other
application where failure of the product could result in personal injury or mate-
rial damage.
Failure to comply with these instructions could result in death or serious injury and mate-
rial damage.
11.
Any changes or repair of the device is not allowed.
Please return device to manufacturer for repair or maintenance.

3 Product description
3.1 Mounting description
Instructions for mounting:
When mounting the instrument, ensure that the sealing faces of the in-
strument and the measuring point are clean and undamaged.
Screw in or unscrew the instrument only via the flats using a suitable tool
(fixed spanner, wrench size 27mm) and the prescribed torque. The ap-
propriate torque depends on the dimension of the pressure connection
and on the sealing element used (form/material).
A maximum torque of 50 Nm must not been exceeded. Do not use the
case as working surface for screwing in or unscrewing the instrument.
When screwing the transmitter in, ensure that the threads are not
jammed.
As described in the installation example the sealing (GDZ-28) must be
made at the face surface of the pressure connection.

3.3 Operating and Maintenance Advice
a.) You must only use the sensor with GMH 3111 - ex, GMH 3151 - ex or GMH 3156 - ex devices!
Usage of other devices may result in destruction of sensor and device.
b) Treat sensor and device carefully. Use only in accordance with above specification. (do not throw, hit against etc.).
Protect plug from soiling.
c) To disconnect pressure sensor adapter cable from the device do not pull at the cable but at the plug (to open
lock).
When connecting the sensor make sure that arrows are pointing upwards and that plug is entered into device
socket centrally. Do not twist plug when entering socket.
If plug is entered correctly, it will slide in smoothly
If plug is twisted or entered incorrectly the connecting pins of the plug can be spoilt by bending or broken
=> Plug can no longer be used and connecting cable needs to be replaced.
d) MSD … .RE - ex (= relative pressure sensor):
Caution: The pressure compensation hole has to be kept clean! It is placed at the back part of the housing.
Do not cover with stickers or similar things!
