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 components against corrosive gases, chemically active dust and moisture.

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 equipment 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 comprising the code letters IP and two digits.
