9.3 Installation

Warning
Never install a damaged drive.
Observe the installation and operating
Note
instructions for the dosing pump.

9.3.1 General notes on installation

• Remove any anti-corrosion agent (that may have
been used for storage purposes) and apply
grease instead.
• Check the cable entries and dummy plugs for
tightness.
• Tighten the hood screws so they are all equally
tight.
• Protect the drive from the effects of the weather
(by means of a canopy, for example).
• Do not attach any ropes, hooks or similar directly
to the drive.
• Continuously overloading and blocking the drive
will damage it.
• Spark-quenching capacitors may adversely affect
the drives' direction of rotation stability and result
in damage.
Cable entries
• When storing, installing and commissioning the
servomotor, care must be taken to ensure that
the cable entries have been properly sealed.
Only cables appropriate for the diameter of the
cable entries must be used.
Installing the hood
• When installing the hood, you must ensure that
the O-rings underneath the hood screws and the
O-ring in the drive housing are properly seated.
• The connection face of the hood must not show
any signs of damage.
• Tighten the hood screws equally.
Housing/Hood
• No additional bores may be drilled into the drive
housing or the hood.
