FOR YOUR SAFETY
Hazards through electrical equipment
Hazards through laser beam
Hazards through explosive or combustible gases and dust
WARNING:
Danger through power voltage
There is a risk of electric shock when working on the system components.
▸
Ensure the power supply can be switched off at an easily accessible and marked
power isolating switch and/or circuit breaker.
▸
When working on the device:
– Only have the work carried out by skilled electricians familiar with potential risks.
– Take suitable protective measures against local hazards and plant-specific
hazards (e.g., free room for movement, cable ducts, automatic switch on).
– Disconnect power supply connections or power lines before working on the
device.
– Only allow personnel carrying out the work to activate the power supply under
consideration of valid safety regulations.
▸
Refit any contact protection removed before switching the power voltage back on
again.
▸
When replacing a removable power line: Observe the specifications ( see “Information
on connection lines”, page 56 ).
▸
When device damage is visible: Switch the power supply off at the external point.
▸
Only use electrical fuses corresponding to the stated ratings (design, breaking
current, trigger characteristic).
WARNING:
Hazard by laser radiation
Laser class 2 device, health hazard in case of irradiation of eye or skin.
▸
Never look directly into the beam path.
▸
Do not point the laser beam at persons.
▸
Avoid laser beam reflections.
WARNING:
Risk of explosion when using unsuitable tools within the Ex-area
Unsuitable tools can be an ignition source when used.
▸
Only use tools approved for the Ex-area.
WARNING:
Risk of explosion when working on device components within the Ex-area
Sparking and static discharge can be a source of ignition.
▸
The device components may only be unpacked, transported, installed, assembled
and disassembled outside the Ex-area.
▸
Never take the packaging material into the Ex-area under any circumstances.
WARNING:
Risk of explosion from escaping gas
There is a risk of explosion due to escaping hot gases when the sender/receiver unit is
pulled out of the duct or the maximum process pressure is exceeded.
▸
Only fit or remove device components when the system is shut down.
▸
Observe the maximum permissible process pressure ( see “Technical data”,
page 124 ), safe operation of the measuring system is not possible when this value is
exceeded.
