3.3 Mounting
The drive should be located as close to the compressor as possible, preferably within 1 meter of the
compressor. To avoid electromagnetic interference please ensure that the motor cables do not cross
or attach to any other connecting cables.
There should be at least a natural air stream inside the cabinet and around the drive to keep the
temperature below 65°C.
There are holes in the drive mounting flange for mounting purposes. These holes will accommodate
M6 sized screws.
The drive should be positioned in a way that the input and output terminals are on the bottom side.
After connecting the input and output cables, one must not forget to place back the protection cover
for the terminals.
Caution: Respect the maximum screw torque to avoid any damage to the frame:
▪
M5 screws: 3.9 Nm
▪
M6 screws: 6.7 Nm
To achieve better cooling it is recommended to mount the drive in the lower or middle part of the
cabinet. Ensure that the drive is mounted in such a way that good natural convection is possible.
Figure 3 shows the minimum clearances to other components near the drive.

3.4 Electrical installation
Please read carefully the safety
instructions in
Chapter 1 and Table 1 !
3.4.1 Earth leakage protection
In all inverter devices like the EV3 drive, earth leakage current (DC, AC) may occur. To protect
against both kinds of leakage currents, an AC/DC-sensitive residual current circuit breaker must be
installed in front of the EV3 drive.
