4.3 Panel mounting / control cabinet installation
4.3.1 Safety instructions for panel mounting / control cabinet installation
The specifications for the operating temperature apply in front of and behind the installation
surface.
The dimensions for the control panel cut-out are a basic prerequisite for the requirements
concerning electrical protection, fire protection and protection rating of the device / system.
However, this alone does not ensure compliance with the requirements. See the following
safety instructions. They must be complied with for the risk assessment by the system creator
(
Ò
Safety instructions).
WARNING
The housing does not meet the requirements concerning protective earth. Only functional
grounding is possible.
w
Risk of electrical shock in case of hazardous active voltages in the control cabinet
behind the installation surface.
u
The system creator must separate hazardous active voltages / parts behind the
installation surface from the housing of the device and its circuits by means of double /
reinforced insulation (air creepage distances, solid insulation).
u
Take single-fault safety into account (e.g. individual core detached from the terminal →
use cable ties).
u
The responsibility for the electrical protection of the system lies with the system creator.
When installing the device in a control cabinet, the following requirements concerning fire protection
apply:
If installed according to the information given in 4.3, the device itself complies with the requirements of
the IEC (or DIN EN) 61010-2-201 for a closed device to prevent fire from spreading.
WARNING
The seal on the housing for panel mounting has no flammability rating and thus presents no
fire obstacle.
w
Fire protection for the system might not be given or might be restricted.
u
The system creator has to ensure the fire protection depending on the requirements of
his/her application, if necessary by means of external precautions.
u
The responsibility for the fire protection of the system lies with the system creator.
Using the installation kit does not ensure the protection rating of the system with the installed
device. The protection rating depends on the properties of the control panel / control cabinet
(e.g. thickness, material, surface characteristics, torsional stiffness).
CAUTION
The use of the installation kit does not ensure the requirements concerning the protection
rating of the system with the installed device.
w
Protection rating and electrical protection might be impaired
u
The system creator has to ensure the protection rating depending on the requirements of
his application, if necessary by means of external precautions.
u
The responsibility for the protection of the system with the installed device lies with the
system creator.
