NOTE!
The end user takes personal responsibility for the EMC compliance of the whole installation.
6. OPERATION INSTRUCTIONS
DANGER!
During operation, do not touch the non-insulated energized parts and never touch or stay
too close to rotating parts.
The rated performance values and the operating conditions are specified on the motor nameplate.
The voltage and frequency variations of the power supply should never exceed the limits
established in the applicable standards.
Occasional different behavior during the normal operation (actuation of thermal protections, noise
level, vibration level, temperature and current increase) must always be assessed by qualified
personnel. In case of doubt, turn off the motor immediately and contact the nearest WEG service
center.

Table 5 - WECM - EMC category compliance for decentralized mounting drive, according to IEC 61800-3
For any other condition different than here described please consult WEG for specifying a solution
that better comply with your installation requirements.
Only Equipment intended to be use in First environment that have a total rated power lower or equal
than 1kW are required to use an external passive filter (PFC) in order to comply with the IEC 61000-
3-2 and comply with the C2 requirement for Low-frequency disturbance voltage as indicated in the
IEC 61800-3 requirements for the electromagnetic compatibility (EMC)
In case the final equipment ascribes to the conditions above, please refer to item 6.6 for more
information regarding the WEG optional PFC filter
Table 4 - WECM - EMC category compliance for drive attached to the motor, according to IEC 61800-3
For optional decentralized mounting the following characteristics are required to comply with
different values of the standard:
