Motors for ATEX / IECEx and Hazardous Location Cl1 Div2
applications. Only specific types of motors LPM-2000 are classified for
the use in Ex classified locations. Refer to the corresponding section in
the manual.
Motors for ATEX / IECEx and Hazardous Location Cl1 Div2
applications. Use only, if necessary, the cooling module ACM-4.3 for
motors installed in Ex classified locations. The use of other materials
for the air cooling module is not allowed.
Motors for ATEX / IECEx applications. Cable and cable glands of the
motor must be protected against impact energy.
For liquid temperatures above 75 °C in Ex applications active cooling
using the cooling module ACM-4.3 is needed.
An Ex conform solution is needed for the motor cable to leave the Ex area (see Figure 5). One option is an
ATEX certified cable sealing system as listed in Table 4 (see Pos. 8) and shown in Figure 2.
A protective earth wire (minimum Wire Gauge AWG14, copper diameter 1.63mm, cross section 2.08mm
2
)
shall be attached to the ATEX / IECEx specific motors by following the instructions outlined below.
1) Motors used without cooling module ACM-4.3
A protective earth wire shall be attached to the ATEX / IECEx specific motor housing by using one of the
eight M4 threads on the backside of the motor.
▪ Remove one of the eight M4 screws on the backside of the motor
▪ Use a crimp cable lug to connect the earth wire
▪ Attach the crimp cable lug with a M4x10mm stainless steel screw, a washer disc, a spring lock
washer and a spacer sleeve (6mm long) to the motor according to Figure 30
