8 - MAINTENANCE
DANGER!
Before any service is performed, ensure that motor is it at standstill, disconnected
from the power supply and protected against accidental energization. Even
when the motor is stopped, dangerous voltages may be present in space heater
terminals;
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.
ATTENTION!
Motor disassembly during the warranty period must be performed by a WEG
authorized service center only;
Regularly inspect the operation of the motor, according to its application, and
ensure a free air flow. Inspect the seals, the fastening bolts, the bearings, the
vibration and noise levels, the drain operation, etc. The lubrication interval is
specified on the motor nameplate.
