Table 2: Environmental conditions
Make sure that the type of housing (protection class) is suitable for the operating
environment:
-
All the cable glands that are not used must be closed hermetically.
-
Check that the speed regulator cover is closed and tightened with the following
torque:
- Sizes A
– C (4 x M4 x 28) 2 Nm,
- Size D (4 x M6 x 28) 4 Nm.
POSSIBLE MATERIAL DAMAGE
Failure to observe the warning could cause damage to the speed regulator!
When installing a cover with an integrated foil keypad, make sure that the flat cable does
not remain stuck.
