Electrical installation
4.1 Before you start
During the installation work it is imperative you avoid ...
y
Screws, cable residue or other foreign objects falling into the device
y
Moisture entering the device
DANGER!
Risk of injury due to electrical power!
Carelessness will result in serious injuries or death.
• Never make or disconnect electrical connections while they are electrically live! Always
disconnect the power before working on the device. Even 10 min. after switching off the
mains supply, dangerously high voltages of ≥50 V may still be present (capacitor charge).
The discharging time depends on the size and the number of devices connected to the multi-
axis system. So check that electrical power is not present!
• Only once the DC link voltage has dropped to a residual voltage of less than 50 V (to be
measured at the DC link busbars) is it allowed to work on the device.
• Any existing additional DC link connections as well as the connections for all components in
the mains input area are to be checked in relation to each other and in relation to earth to
ensure they are not carrying any electrical power. If necessary, all cable connections are to
be discharged using suitable means.
NOTE:
During the installation of the axis controller in a KeDrive D3 system, it is
imperative the operation manuals for the other devices (controller, supply unit)
are also followed.
4.2 Effective EMC installation
Compliance with the EMC product standard
Commissioning, i.e. starting up intended operation, is only permitted while strictly
complying with the EMC Directive (2014/30/EU). The installer/organisation operating a
machine and/or system must provide proof of compliance with the protection targets
stipulated in the standard.
The essential EMC measures are already implemented in the design of the devices in
the form of optimised housing shielding, printed circuit board layout, filter measures and
selection of suitable connectors with shield plate. In addition to the internal measures,
the following installation measures are to be noted:
Routing of cables
y
If possible, signal cables should only enter from one side into the switch
cabinet.
y
It is recommended to twist wires in the same electrical circuit.
y
Avoid unnecessary cable lengths and "loops of spare cable".
Shielding measures
y
Do not strip back the cable shields too far and use the shield lugs on the
related connectors for making the connection to the components, see Figure
4.1. Connect the other end of the cable shield to the PE rail (main earth) or the
backing plate with a large area connection.
Cable type
y
Use only shielded cables with double copper braiding with 60% to 70%
coverage. To connect KEBA servomotors we recommend the usage of ready-
made motor and encoder cables from KEBA, as all EMC tests have been
undertaken successfully with these cables.
NOTE:
If connection cables from other suppliers are used, these cables must as a
minimum be equivalent. However, an assurance of stable, reliable operation
with such cables cannot be given by KEBA.
