4.1 Lubrication of motor bearings
4.1.1 Grease and lubrication intervals
The recommended grease type and quantity and the recommended lubrication intervals in hours appear from the
lubricating plate fitted to the motor. When the MGE-F has reached the prescribed number of operating hours, it will give
a lubrication warning (fig.
17
) that will appear on the R100 or PC Tool E-products. See section
2.6 Alarms and warnings
.
4.1.2 Lubrication procedure
1. Connect the grease gun to the lubricating nipples, and apply the prescribed quantity of grease.
2. Confirm the lubrication in the
INSTALLATION
menu of the R100. See fig.
18
. Confirmation can also be made
via PC Tool E-products.
Warning
All service work must be carried out by specially trained staff.
Warning
Due to the capacitors of the MGE-F, touching live electrical parts may be fatal, even after the
mains supply has been switched off.
Disconnect the mains supply, and as a minimum wait the amount of time stated on the warning
label under the terminal box cover before touching any live parts.
Note that the relay may be connected to an external power supply and still be live after the
mains supply to the motor has been disconnected.
Warning
The MGE-F may be hot!

Bearings need to be lubricated
Caution
The motor must be running during the lubrication. This ensures that new grease is distributed
evenly and that old grease is pressed out of the bearing.
