Only specific types of motors LPM-600 are classified for the use in Ex
classified locations. Refer to the corresponding section in the manual.
Motors for ATEX / IECEx applications. Use only, if necessary, the
cooling module ACM-600.3 for motors installed in Ex classified
locations. The use of other materials for the air cooling module is not
allowed.
An ATEX / IECEx conform solution is needed for the motor cables to leave the Ex area (see Figure 5). One
option is an ATEX certified cable system as listed in Table 4 and shown in Figure 2.
A protective earth wire (min. AWG 14, copper cross section 2.08 mm

) shall be attached to the ATEX /
IECEx specific motor housings by using one of the four M5 threads on the backside of the motor by following
the instructions outlined below.
1) Motors used without air cooling module ACM-600.3
• Remove one of the four M5 screws on the backside of the motor.
• Use a crimp-type end together with a spacer sleeve to connect an earth wire.
• Attach the grounding wire with a M5 stainless steel screw to the motor according to Figure 31.
