Installation and commissioning
Generator installation for iMAPLA 8, 13, 17 and 20
y
Secure the generator with at least four mounting screws
(minimum M8 or comparable, bolt grade
min. 8.8).
y
The attachment must be permanent and
resistant to shock and vibrations.
y
Use suitable means to prevent the screws
from coming undone by themselves,
e.g. via a tension ring according to DIN 128.
