DANGER!
g

from the power supply and protected against accidental energization. Even when the
motor is stopped, dangerous voltages may be present in space heater terminals;
g
For motors with permanent magnet rotor (WECM and Emerald eZA), the motor
assembly and disassembly require the use of proper devices due to the attracting or
repelling forces that occur between metallic parts. This work must only be performed
by a WEG Authorized service center specifically trained for such an operation.
People with pacemakers cannot handle these motors. The permanent magnets can
also cause disturbances or damages to other electric equipment and components
during maintenance.
