An explosion can occur. This can result in death, serious injury or material damage.
• For this reason, the relative characteristics must be considered both for gas (zones 0, 1 and
2) and for dust (zones 20, 21 and 22) where hybrid mixtures arise. It is necessary for a
competent assessor to determine in the individual case whether the parameters determining
ignition are unfavorably affected in a particular hybrid mixture.
• Motors with dual plates for G ("Gas") and D ("Dust") may only be used where these two occur
after prior examination of the properties of the hybrid mixtures by the user.
• These explosion-protected machines are not suitable for hybrid explosive environments. Use
in atmospheres where there is a risk of explosion caused by both gas and dust simultaneously
is absolutely prohibited.
Special conditions for explosion-protected machines
The machine has an "X" marking (for EACEx in the Ex marking, for ATEX, IECEx and UKCA, in the
certificate number). To ensure safe operation in hazardous areas, the special conditions of the
certificate specified on the nameplate must be strictly complied with:
EPS 18 ATEX 1 202 X, EPS 18 ATEX 1 203 X, IECEx EPS 18.0104X, EPS 21 UKEX 1 250 X,
EPS 21 UKEX 1 255 X
• It is not permissible to operate groups of motors connected to the converter.
• The rated converter current may correspond as a maximum to twice the rated motor current.
• It is only permissible to operate the motor with a SINAMICS converter or a converter that is
comparable.
• When commissioning the system, with reference to the rated voltage U
insulation, carefully ensure that no converter-related overvoltages with a peak value
exceeding (1.1 · √2 · U
• If the motor is equipped with anti-condensation heating, using an interlock circuit, ensure
that the anti-condensation heating can only be operated when the motor is shut down.
• Once the motor has been shut down, the anti-condensation heating may only be switched
on after a specified wait time has elapsed. The information provided in the Operating
Instructions must be strictly complied with.
• If the motor is equipped with a separately driven fan, using an interlock circuit, ensure that
the motor can only be operated when the separately drive fan is switched on.

Material damage due to electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge. These
components can be damaged or destroyed if they are not handled correctly. To protect
equipment against damage, follow the instructions given below.
• Only touch electronic modules if you absolutely have to work on them.
• The body of the person concerned must have been electrostatically discharged and
grounded immediately before any electronic modules are touched.
