47. Electrical connection
The motor is connected in accordance with the data shown on the nameplate and per
the accompanying circuit diagram. Ensure that the terminal links are correctly placed
and all connections, including the protective earth conductor, are screwed tightly. To
protect the motor from being overloaded, appropriate protective devices must be
provided. Fuses do not give this protection. For motors with high starting frequencies
the conventional motor protection is insufficient; and it is advisable to purchase these
motors with thermistors imbedded in the windings and to monitor them with an
external tripping relay. In this manner the motors are fully protected against practical
all possible overloads.

48. Maintenance Plan
For motors up to and including size 160 it is sufficient to keep the cooling passages
cleaned and to check the bearings. These motors have bearings with service life
lubrication. If the motor is being overhauled the bearings are to be replaced. Motors
larger than size 160 are provided with a lubricator. In addition to keeping the cooling
passages clean, the bearing should be checked regularly and re-lubricated with a
grease pump according to the schedule below.
As soon as the maximum number of re-lubrications is exceeded, the old grease must
be removed from the grease chambers and bearings, after which these must be
cleaned thoroughly. Next the inner chambers and the bearings must be provided with
new grease. The outer chambers may not be filled with grease. For the lubrication of
the bearings a grease lubricant must be used that consists of mineral base oils and a
thickening agent with a base of lithium soap or a lithium soap complex, having a
consistency class of 3 according to NLGI.
