1.4.1 Mains Supply Requirements
Each time prior to switching on, check that the mains supply meets the
requirements of the supply module being used (see supply module
documentation).
1.4.2 Checks with the Equipment Switched Off
The installed drive components must be designed for the existing input
voltages. The input voltages shown on the rating plate should be
checked against the type code (see respective drive and supply module
documentation).
The details on the AS programming module must match the ratings of the
installed drive components, otherwise there is a risk of damage.
Check the wiring for short-circuits, breaks, incorrect connections,
conductor cross sections and identify these against the Indramat
connection diagram.
• Earthing arrangements:
The earthing arrangements should be made exactly as per the
respective connection diagrams. These should also include the rele-
vant protective measures for the machine. Each motor must be
earthed at its associated drive module.
Drive modules should be separately earthed at the power supply
module. The earthing point of the supply module is the central
reference earth point for all drive components. This should be connected
to the mains earth. The above earth connections provide an operational
earth with a protective function.
When installing the modules in the control cabinet, ensure that the
housing makes a good electrical connection with the control cabinet.
Otherwise faults could occur.
• Twisting the load conductors:
The motor connections from the main drive module should be either
twisted or a four-core cable (3 x phase, 1 x earth) should be used.
• Connections to auxiliary modules:
The power connections to the additional capacitance module or to
further additional storage capacitors should be twisted and kept as
short as possible.
• Power connections to the main drive modules:
Normally, the units are alongside each other and the connection is
made via two busbars. If this is not possible, then the power connection
must be made with two twisted 16 mm
2
conductors not more than one
meter in length.
The cross sections of conductors must be such that the permissible
current densities stipulated by the relevant specifications (VDE 0100 and
VDE 0113) are not exceeded at the maximum ambient temperatures and
the corresponding continuous motor and transformer currents.
