Installation instructions for the basic unit
Installation
Operating
braking resistors
•
The connection leads to the braking resistors carry a high pulsed DC voltage during
rated operation.
Binary inputs /
binary outputs
•
The binary inputs are electrically isolated by optocouplers.
•
The binary outputs are short-circuit proof and protected against external volt-
age to DC 30 V. External voltages > DC 30 V can cause irreparable damage to
binary outputs.
EMC compliant
installation
•
Only use shielded control cables.
•
All cables except for the supply system lead must be shielded. As an alternative to
the shielding, the option HD.. (output choke) can be used for the motor cable to
achieve the emitted interference limit values. .
•
When using shielded motor cables, e.g. prefabricated motor cables from SEW-
EURODRIVE, you must keep the unshielded conductors between the shield and
connection terminal of the inverter as short as possible.
•
Apply the shield by the shortest possible route and make sure it is grounded
over a wide area at both ends. Ground one end of the shield via a suppression ca-
pacitor (220 nF / 50 V) to avoid ground loops. If using double-shielded cables, ground
the outer shield on the controller end and the inner shield on the other end.
•
You can also use grounded sheet-metal ducts or metal pipes to shield the ca-
bles. Route the power and control cables separately.
•
Provide high frequency compatible grounding for the inverter and all additional
units (wide area metal-on-metal contact between the unit housing and ground, e.g.
unpainted control cabinet mounting panel).
WARNING!
The surfaces of the braking resistors get very hot when the braking resistors are loaded
with P
rated
.
Risk of burns and fire.
•
Choose a suitable installation location. Braking resistors are usually installed on top
of the control cabinet.
•
Do not touch the braking resistors.
