Note
The components are insulated in compliance with DIN EN 50178.
S
Overvoltage category III for industrial line supplies
S
Degree of pollution II, especially no conductive pollution, moisture
condensation is not permissible
S
Installation altitude up to max. 2000 m above sea level
S
Installation altitude 2000 m – 6500 m possible in conjunction with isolating
transformer with neutral point on grounded the secondary side, grounded
module housing.
S
As a result of the "thinner air" (poor thermal dissipation), above 1000 m, the
drive power must be derated (reduced). Refer to Chapter C.1.3 and 5.4.
S
Star point of the line supply is directly grounded, the module housing is
grounded.
According to EN 61800–5–1 and UL 508 only protective extra low voltages with
safety separation may be connected at all connections and terminals of the
electronic modules.
Warning
Any conductive dirt/pollution can result in the safe electrical separation
being lost and can therefore result in hazards to personnel (electric
shock).
Note
Appropriate measures (filter, waiting cycles, etc.) must be adopted to prevent
contamination of the cooling system, because otherwise fan damage and thus
loss of the cooling effect can occur.
