Removing The External Fan; Removing And Mounting The Speed Encoder - Siemens SIMOTICS M-1PH8 Operating Instructions & Installation Instructions

Mount the machine on an alignment plate. This ensures that the contact surfaces of the motor
feet are all on the same level.
CAUTION
Do not damage windings
Windings protrude from the stator housing and can be damaged when attaching the end
shield. This can damage the motor.
When mounting the end shield, ensure that the windings that project from the stator housing
are not damaged.
Sealing the motor
● Clean bare joints between parts before re-assembling (e.g. between enclosures, end
● Brush the bare joints with the non-hardening sealing agent " Hylomar M".
● Note that these joints between parts (e.g. the sealing gap on the active part of the bearing)
● Check the sealing elements fitted (e.g. at the terminal boxes) and replace them if they do
● Follow the manufacturer's application and safety instructions when using the sealant.
● Replace parts that are subject to wear such as the adjusting springs.
