SINAMICS G150
Drive converter cabinet units
75 kW to 2700 kW
Coated modules
The following converter components are equipped as standard
with coated modules:
•
Power Modules
•
Control Units
•
Sensor Modules
•
Terminal Modules
•
Advanced Operator Panel (AOP30)
The coating on the modules protects the sensitive SMD compo-
nents against corrosive gases, chemically active dust and mois-
ture.
Nickel-plated busbars
All of the copper busbars used in the converter cabinet are
nickel-plated in order to achieve the best possible immunity to
environmental effects. The bare copper connections also do not
have to be cleaned for customer connections.
Note:
With some options, parts of the copper busbars cannot be
nickel-plated for technical reasons.
Degrees of protection of the cabinet units
The EN 60529 standard covers the protection of electrical equip-
ment by means of housings, covers or equivalent, and includes:
•
Protection of persons against accidental contact with live or
moving parts within the housing and protection of the
equipment against the ingress of solid foreign bodies (touch
protection and protection against ingress of solid foreign
bodies)
•
Protection of the equipment against the ingress of water
(water protection)
•
Abbreviations for the internationally agreed degrees of
protection
The degrees of protection are specified by abbreviations com-
prising the code letters IP and two digits.
