Cautions and warnings

■

Please note the advices in our data book “EMC Filters” (latest edition). Attention should be paid

to the chapter “General safety notes”.

■

It shall be ensured that only qualified persons (electricity specialists) are engaged on work such

as planning, assembly, installation, operation, repair and maintenance. They must be provided

with the corresponding documentation.

■

Danger of electric shock. SineFormer contain components that store an electric charge. Danger-

ous voltages can continue to exist at the filter terminals for longer than five minutes even after

the power has been switched off.

■

The protective earth connections shall be the first to be made when the SineFormer is installed

and the last to be disconnected. Depending on the magnitude of the leakage currents, the par-

ticular specifications for making the protective-earth connection must be observed.

■

Impermissible overloading of the SineFormer, such as with circuits able to cause resonances,

impermissible voltages at higher frequencies etc. can lead to bodily injury and death as well as

cause substantial material damages (e.g. destruction of the filter housing).

■

SineFormer must be protected in the application against impermissible exceeding of the rated

currents by overcurrent protective.

■

In case of leakage currents

> 3.5 mA you shall mount the PE conductor stationary with the re-

quired cross section before beginning of operation and save it against disconnecting. For leak-

■

The information, specifications and values contained in this data sheet are based on our know-

lege of typical requirements that are often placed on SineFormer. It is incumbent on the customer

to check and decide whether this SineFormer is suitable for use in a particular application.

■

In particular the values with regard to “temperature” and “noise” have to be observed.

2) The KU value (symbol KU) is a classification parameter of safety-referred failure types designed to ensure protec-

tion against hazardous body currents and excessive heating.

A value of KU = 4.5 with respect to interruptions is attained:

and line layout correspond to the requirements for PEN conductors as specified in relevant standards.
