*The coolant flow speed is the speed of the medium flowing along the motor casing during normal
operation.
In the event of higher media temperatures, operation is only allowed if you
use a special winding PE2/PA,
reduce the performance (De-Rating, see Appendix),
increase the coolant flow speed.
If a leak is visible or if the motor is more than one year old (e.g. in the event of re-use or after long storage):
Check the fluid level in the motor prior to installing it.
You need the following tools for assembly and inspection work:
Insulation measuring unit: 500 VDC testing
Filling Kit 308 726 103
Determine the age of the motor by checking manufacturing code near the type plate (see Figure 5-1).
Figure 5-1: manufacturing code with date and place of manufacture
Motor damage due to being insufficiently filled!
Fill the motor with sufficient motor fluid
Wear safety goggles and gloves when filling and draining the motor.
Top up using original motor fluid from Franklin Electric FES93 (concentrate FES92 id. no. 308
353 941, 5-liter container) or clean drinking water.
Never use distilled water!
