13-1 Installation environments
The Axpert-Eazy conforms to the EN 61800-3 Category C3. Installing Axpert-Eazy with stand-alone is
recommended to use in Industrial Environment, ensure that no device or equipment is installed
adjacent to the drive that is intended for the Residential, Commercial and Light Industrial
Environments only, as interference with such equipment may occur.
13-2 Input filters and their connections
WARNING
Electrical shock hazards. The input filter terminals must be fully covered with appropriate
insulation material to avoid electrical shocks.
Electrical shock hazards. The input filters must be fully earthed. Otherwise, there may be a risk of
electrical shocks and the effectiveness of filters will be impaired.
In most cases, the input filter should be installed as closely, approximately 0.5 meter (20”) to the drive
as possible to ensure its effectiveness. This may be changed, if, for instance, a complete system is
filtered in its entirety. In this case, the whole system would require testing to ensure EMC compliance.
Ensure that the input filter is securely and effectively earthed. If the drive is installed on a metal plate,
install the filter on the same plate and then earth the plate. This is effective to reduce EMI.
13-3 Wiring & Earthing
Select the input cables from those specified in the manual
The output cable from the drive must be screened or armored and the screen or armor must be
connected to the earth as shown in fig. 13-1
Ensure that the input and output cable are not installed in parallel to each other. Keep them apart
from each other by at least 0.5 meter (20”)
Ensure that the screen of the output cable is earthed at both ends with one end connected to the
drive’s earth terminal and the other end to the motor earth
Arrange the termination at the drives end inside the enclosure. If it is not possible to terminate the
cables inside the enclosure then terminate them as closely to the drive’s conduit hole as possible
(preferably within 0.1 meter (4”))
If the screened output cables are over 5 meters (16.6’), this may cause a problem arising from a
floating capacitance, such as undesirable surge voltage increase at the motor terminals, electrical
noises from the cables when they discharge capacitance, or increase in leakage currents. In this
case, it is recommend to use output chokes
Use a 0.13mm
2
(AWG 26) to 0.8mm² (AWG 18) wire for wiring to the control circuit and should be
screened if they are used for a speed setting circuitry, analogue signal circuitry for metering, or
relay signal circuitry. The screen should be connected to the drive's earth or COM terminal only
(refer to Fig. 13-1)
Control cables should be selected in accordance with the instructions in the drive's manual. The
control leads should be wired away from the power cables. If it is not possible, cross them at the
right angle, and if they are laid down alongside each other, ensure to separate them by at least
0.5 meter (20”)
When the section, which runs along the power cables, exceeds 10 meter (33.3’), separate them
further more. The control cables should not share the same conduit hole of the drive with the
power cables. Separate analogue control leads from relay control leads
To reduce emission and to increase immunity, ensure that no control cables are connected that is
not used. Also, wire them in such manner that they are as short as possible
Put the relay signal controller and analog speed-setting controller, analog signal meters in a metal
box
Keep the earthing cable of drive, motor and filter as short as possible and is installed in
accordance with the local requirements. Use low impedance earthing cables
