2.2
Assembly and operating instructions
DANGER
Risk of explosion!
Risk of explosion due to formation of sparks.
Devices with housing components made of aluminum can
form an ignition source, as sparks occur due to mechanical
friction or impact.
— When working on the devices, only use tools that are
approved for working with aluminum in potentially
explosive atmosphere.
— Avoid mechanical friction and impacts on aluminum
components.
2.2.1
Protection against electrostatic discharges
DANGER
Risk of explosion!
The painted surface of the device can store electrostatic
charges. As a result, the housing can form an ignition source
due to electrostatic discharges in the following conditions:
— The device is operated in environments with a relative
humidity of ≤ 30 %.
— This painted surface of the device is therefore relatively
free from impurities such as dirt, dust or oil.
The instructions on avoiding the ignition of hazardous areas
due to electrostatic discharges in accordance with the
EN TR50404 and IEC 60079-32-1 standards must be
observed!
Instructions on cleaning
The painted surface of the device may be cleaned only using a
moist cloth.
2.2.2
Opening and closing the housing
DANGER
Danger of explosion if the device is operated with the
transmitter housing or terminal box open!
Before opening the transmitter housing or the terminal box,
note the following points:
— Check that a valid fire permit is available.
— Make sure that there is no explosion hazard.
— Before opening the device, switch off the power supply
and wait for t > 2 minutes.
WARNING
Risk of injury due to live parts!
When the housing is open, contact protection is not provided
and EMC protection is limited.
Before opening the housing, switch off the power supply.
See also chapter "Opening and closing the housing" on
page 28.
For sealing original spare parts should be used only.
