4.3 Storage/Downtimes

• Store the servomotor in a well ventilated, dry room on a pallet
or rack (protected from moisture). Cover it with foil to protect it
from dust and dirt.
• Prevent condensation from forming (e.g. if the temperature
fluctuates).
If the servomotor is to be stored for longer than 4 months,
observe the following points too:
• Insert a layer of absorbent material underneath the drive's
cover.
Keep the gas dosing system in a dry, cool place.
4.4 Installation

Caution surface only.
Danger of warping!
Warning
It is a basic fact that certain parts will carry a
dangerous voltage whenever electrical devices are
operated. Only electricians or trained persons
instructed and supervised by a specialist electrician
may carry out work on electrical installations or
equipment and the relevant electrotechnical rules
must be observed.
Warning
When undertaking installation, commissioning and
testing work, all applicable safety and accident
prevention regulations must always be observed.
Warning
Before you start any (installation) work of any kind on
the drive, make sure that all affected machines/
installations are switched off.
It is essential that you read this instruction manual

dosing system ready for connection.
General notes on installation
• Check the cable entries and dummy plugs for tightness.
• Tighten the hood screws so they are all equally tight.
• Continuously overloading and blocking the drive will damage
it.
• Spark-quenching capacitors may adversely affect the drives'
direction of rotation 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
