General safety instructions
Maintenance and servicing
The components are maintenance−free if the required operating
ƒ
conditions are observed.
If the cooling air is polluted, the cooling surfaces may be contaminated or
ƒ
the air vents may be blocked. Under these operating conditions, the
cooling surfaces and air vents must be cleaned at regular intervals. Never
use sharp objects for this purpose!
After the system has been disconnected from the supply voltage, live
ƒ
components and power connections must not be touched immediately
because capacitors may be charged. Please observe the corresponding
notes on the device.
Disposal
Recycle metals and plastic materials. Ensure professional disposal of
ƒ
assembled PCBs.
