SINAMICS G120P Cabinet
Coated modules
The following converter components are equipped as standard
with coated modules:
•
Power Modules
•
Control Units
•
Intelligent Operator Panel IOP
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 busbars used in the converter cabinet are nickel-plated
in order to achieve the best possible immunity to environmental
effects. Further, the bare copper connections do not have to be
cleaned for customer connections.
Note:
For some options, for technical reasons, parts of the copper
busbars cannot be nickel-plated.
EMC shielding busbars and PE busbars
The Cabinet Modules are delivered with a EMC shielding busbar
and a PE busbar as standard. The EMC shielding busbar is used
to connect shielded power cables for line and motor supply ca-
bles. The PE busbar is used to connect and secure PE cables.
Crane transport aids
The converter cabinet units are supplied with a crane transport
aid mounted on the top. In the case of single cabinets up to a
width of 1200 mm (47.2 in), transport eyebolts are provided to
transport the unit by crane. Transport rails are used with cabinet
widths >1200 mm (47.2 in) or for several cabinets (e.g. option
L01
). Rope spreaders should be used for low crane hook
heights.
Degrees of protection of 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 matter
(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.
Degrees of protection of the converter cabinet unit

(touch protection and protection against ingress of
foreign solid matter)
Second digit
(protection of the equipment against the ingress of
water)

Dust protected.
Ingress of dust is not totally prevented, but dust
must not be allowed to enter in such quantities
that the functioning or safety of the equipment is
impaired.
