General safety precautions
• This device must only be installed and operated in accordance with instructions and warnings of the tech-
nical documentation.
•
Only qualified personnel is allowed to install and operate this device.
• The data logger‘s power supply is done by a lithium ion rechargeable battery.
• When installing and operating these devices, please note the following safety instructions:
• Only charging units delivered by manufacturer must be used. Failure to do so will result in serious damage
to the device and in accidents.
• Pay attention to the integrity of all connection lines. In the event of cable damage, the device must be
deactivated at once. Please contact manufacturer for repair.
• Do not short-circuit the rechargeable battery
, do not open it, do not throw it into fire, do not extinguish it
with water!
EXPLOSION HAZARD!
•
If fluid from battery pack gets on your skin or into your eyes, rinse with plenty of water and see a doctor.
• Do not use damaged rechargeable batteries!
Attention: The device consists of electrostatically sensitive components. Pay attention to the
ESD operation instructions when handling with this electronics!

Special conditions for use in potentially explosive gas atmospheres of the
zone 2
• Mounting and connecting the device must only be done if there is no
potentially explosive atmosphere.
•
Connecting and disconnecting the plug connectors is only permitted if there is no explosive atmosphe
re.
Unused sockets must be closed with dedicated protective caps.
• Unplugged connectors are not permitted in hazardous areas. Always remove unplugged connectors from
hazardous areas!
•
Opening the case must only be done if there is no potentially explosive atmo
sphere.
•
The case must only be cleaned by using wet cloths, otherwise there is the danger of spark ignition by
electrostatic discharge.
•
The „online outlet“ for data transmission and data logger configuration must only be used in case of no
ne-
xistence of an explosive atmosphere. If not used, the „online outlet“ must be closed with the dedicated cap.
• Charging the accumulator must only be done outside potentially
explosive areas.
•
Check whether there is a necessity of embedding into the potential equalization of the equip
ment or the
metering point
! This potential equalization can happen via process (pressure) connection of the data log
-
ger or via the dedicated ground connection.
Note:
The data logger‘s battery circuit is grounded at the case.
All subsequent modifications to the device result in the consequence that a secure use
is no more
guaranteed within ex-zone 2 and the EU-declaration of conformity loses its validity.
