General safety instructions and application notes for Lenze drive controllers
Operation
You must equip the drive controllers installed with additional monitoring
equipment and protective equipment as per the applicable safety stipulations,
if necessary (e.g. law on technical equipment, health and safety regulations).
You are allowed to adapt the drive controller to your application. Pay attention
to the instructions in the documentation during this process.
It is not allowed to touch live components or power terminals immediately after
isolating the drive controller from the supply voltage, as capacitors may be
charged. Pay attention to the related labels on the drive controller.
Keep all protective covers and doors closed during operation.
Note for UL-approved systems with built-in drive controllers: UL warnings are
instructions that only apply to UL systems. The documentation includes special
instructions for UL.
Maintenance and servicing
The drive controllers are maintenance-free on compliance with the stipulated
operating conditions.
In case of dirt-laden ambient air, the cooling surfaces on the drive controller may
become soiled or cooling openings clogged. For this reason, in these operating
conditions regularly clean the cooling surfaces and cooling openings. Never use
sharp or pointed objects for this task!
Disposal
Send metals and plastics for recycling. Properly dispose of populated printed
circuit boards.
It is imperative you follow the product-specific safety instructions and
application notes in these instructions!
