4.2.2.3
Hand-held Technology Units for ATEX Zone 22 3D
All hand-held technology units are not approved for continuous use in the ATEX Zone 22 3D. The may
therefore only be used during commissioning or for maintenance purposes, if it is ensured that no explosive
dust atmosphere exists.

ATTENTION
The diagnostic opening of the basic unit for the connection of a hand-held
technology unit or a PC must not be opened in an atmosphere containing
explosive dust.

ATTENTION
If an internal braking resistor of type SK BRI4-x-xxx-xxx is used, the power limitation for
this must be activated under all circumstances. This is usually done by setting DIP
switch 8 to "ON". Alternatively, parameters (P555), (P556) and (P557) can be
parameterised with the appropriate values. Only the resistors assigned to the relevant
inverter type may be used.
