D GENERAL INSTALLATION GUIDELINES

D.1 Connecting the protective conductor

For safety reasons and for reasons of the Electro-Magnetic Compatibility (EMC) an optimalprotective ground terminal has to be assured.

The protective conductor (PE) or the ground of the vehicle is to be connected via the star-point(central GND bar) in the switchgear cabinet to the ground screw provided for on the systemhousing and/or the controller case (see illustration D.1 and illustration D.2).

This measure serves to improve the interference immunity.

ATTENTION: From ground screw (PE) of the system housing a connection of wire cross-section min. 2.5mm must be leaded as short as possible to the PE section ofthe power supply unit or chassis/ground in the vehicle.

When using connectors featuring metal hoods and a shield, it ispossible to eliminate an additional overall-shield connection to theground terminal of the control unit housing.

In the case of shielded cables use always metal hoods.

The metal hoods must be conductively fastened to the housing.

In the case of potential differences between several PE - (GND) - points(e.g., in the case of separated power supplies via different circuits) theshield of the connecting cable must only be grounded on one sideof the control unit.

If twisted-pair, shielded cables are used the connector housings has tobe connected to GND too.

The individual shields on the open cable end mustnot be connected to the overall shield or PE.

D.3 General wiring guidelines

The following wiring rules should always be considered:

PE-conductors must always be wired according to VDE-regulations or equivalent regulations.

In addition, the whole mounting plate is to be used as a grounding surface.

That means: all metal parts such as housing, rails etc. are to be connected via short low-resistanceHF-connections to the mounting plate (braided Cu-conductors, nickel-plated screws etc.).

ATTENTION: The connecting points must be free from coating/oxide, i.e., prior to connectionthe varnish/coating has to be removed from the surface (see Figure D2)

The areas of the control electronics, power electronics and mains-ON/OFF must be geometricallyseparated (they must not be located next to each other). This area of separation also applies to theclosed cabinet door.

ATTENTION: All the metal parts must have low-resistance HF-connections.

1. Bright and bare connecting points

2. Surfaces protected against corrosion, e.g.: nickel-plating.

3. If possible, no oxide films on the blank surface (no coating or anodization)!

4. Connections of large-surface contact

5. Connections must be as short as possible

Beside to the normal connection to PE or GND, the VDE-rules or their equivalents of othercountries have to be considered with respect to metal parts and their HF-characteristics.
