General safety guidelines
Power Panel T30
devices are suitable for use in environments described in chapter
, section
"ATEX Directive 2014/34/EU" on page 131
. The wiring must be in accordance with the
respective national regulations. All cables used must be able to handle a surface temperature of at least 70°C.
Additional equipment must also be approved for the respective environment. Devices must be used in suitable
protective housings and final assembly must be inspected and approved by the local authorities.
Devices with
explosion protection are to be used as intended and are only permitted to be operated by knowledgeable
and qualified personnel according to these operating instructions and the corresponding user's manual.
Operation in any other way endangers the safety and functionality of the devices and the connected systems. The
operator is responsible for following all applicable safety and accident prevention regulations, as well as adhering
to standards.
Installation
The devices must be installed in accordance with the instruction in the user's manual. The Power Panels must be
installed in a wall cutout of an inspected and certified housing with EPL "Gc" or "Dc" (e.g. control cabinet). In order
to guarantee sufficient air circulation, allow the specified amount of space around the device. During installing,
make sure that the risk of mechanical hazards is low. When exposed to UV light, plastics can age prematurely and
become brittle. The devices must therefore be protected against excessive ultraviolet light (direct sunshine).
Installation
The devices must remain voltage-free until installation work is complete. The devices must be connected with
the potential equalization system. Strain relief must be implemented for all connectors, as described in the user's
manual.
Maintenance
Accumulated dust must be removed regularly. Electrostatic charges must therefore be avoided. The devices must
therefore only be cleaned with damp cloths.
Breakdowns and disassembly
The devices must be shut down and protected against accidental startup. Defective devices must only be replaced
by knowledgeable and qualified personnel.
