Electromagnetic Compatibility

The following guidelines are provided for EMC installation compliance.

General Notes for Bulletin 284 Devices

• The motor cable should be kept as short as possible to avoid electromagnetic emission as well as

capacitive currents

• Conformity of the device with CE EMC requirements does not guarantee an entire machine

installation complies with CE EMC requirements. Many factors can influence total machine and
installation compliance.

• Using an EMI filter with any ArmorStart device rating, may result in relatively high-ground leakage

currents. Therefore, the filter must only be used in installations and solidly grounded (bonded) to the
building power distribution ground. Grounding must not rely on flexible cables and should not include
any form of plug or socket that would permit inadvertent disconnection. Some local codes may require
redundant ground connections. The integrity of all connections should be periodically checked.

Ground the ArmorStart Controller

Connect a grounding conductor to the terminal provided as standard on each ArmorStart Distributed Motor
Controller.
