The following power range must be observed: 90 VAC ... 264 VAC.
Ensure that power is turned off when the cover of the AMC-AC is off because dangerous
voltages are exposed.
When inserting option cards, ensure the cover is on before powering on the unit.
Protection against short-circuits
Important! Ensure that the 1645 AMC units have reached room temperature and are
dry before taking them into operation.
Electrostatic discharge
Introduction
Electrostatic discharge (ESD), caused by touching with the hand for example, can destroy
semiconductor components. The correct operation of the complete system is then no
longer assured.
Industry experience has shown that all semiconductor components can be damaged by
static electricity that builds up on work surfaces and personnel. The electrostatic
discharge can also affect the components indirectly via contacts or conductor tracks. The
electrostatic charges are produced by various charging effects of movement and contact
with other objects. Dry air allows greater static charges to accumulate. Higher potentials
are measured in areas with low relative humidity, but potentials high enough to cause
damage can occur anywhere.
The barred-hand symbol
Circuit packs containing components that are especially sensitive to electrostatic
discharge are identified by warning labels bearing the barred-hand symbol.
