4 Installation

Legal principles and standards

On installation according to regulations the KE/KW unit combinations comply with the limits of the EMC product standard

(according to variable speed drives EN 61800-3, Table 11 for power drive systems in the area of application of the second

environment [industrial areas]). For use in the first environment (residential areas) additional discrete filter components must be

installed. Consultation with AMK is required for this, measurements on site in the plant must be performed.

The EMC measurements were performed specifically on a drive system constructed as an example with 1 KE and 4 KW

modules with different motor cable lengths. The results cannot be generalized to every installation. Therefore EMC tests by the

user are required on site for proof of CE conformity.

General:

The KE/KW modules must be installed on a liquid or air-cooled AL mounting plate. The temperature of the plate must be

kept below 40°C, condensation is not permitted.

Preferred installation position: vertically (ACC BUS above) or horizontally (controller card KW-R0x below). Other

installation positions are permitted only after consultation with AMK.

To guarantee sufficient air circulation in the unit interior, a minimum clearance of 100 mm above and below the unit must

be complied with. Installation cables may not impair the air inlet and outlet. External units may not influence the air

temperature at the intake point (bottom of unit).

The power choke needs to be installed with a minimum distance of 80 mm to the KE/KW module.

Before installation of the modules the mounting surfaces must be thoroughly cleaned. The unit rear panel must be

protected against damage in transport and installation work.

The pressure bolts in the centre of the unit must always be fastened first, the mounting screws are then tightened.

Option cards may be changed only by trained service personnel. The installation instructions can be found in the

description for the option card.

Lock the power connection plug X20 on the KE module with the vibration-proof screw union.

Arrangement of the devices see DC BUS wiring and arrangement of the KE/KW- Moduls on page 38

4.1 Control cabinet

The KE/KW units are intended for installation in a closed, sufficiently dimensioned control cabinet, which offers protection

against direct contact according to EN 50178. (Protective category of the KE/KW units: IP20, control cabinet IP54).

During storage, installation, wiring, start-up and during operation the KE/KW units must be protected against penetration of

foreign bodies. Special attention must be paid to penetration of condensation by cooling units. The safety and function of the

drive system is otherwise not guaranteed.

The units are designed for degree of contamination 2 according to EN 50178. Temporary condensation may occur only

as long as the units are out of service. There must be no condensation present after application of the line voltage.

The supplied air must be dry and free of electrically conductive dusts, fibres, gases and vapours.

As required suitable filters must be used or other protective measures performed.

4.2 Notes on the control cabinet construction suitable for EMC:

The EU Machinery Directive requires compliance with the EMC limits for the complete machine/plant. According to the EMC law

the manufacturer and supplier of the total plant is responsible for compliance with the limits of this plant.

Here a few basic rules for control cabinet construction and cabling which contribute to improving the EMC behaviour of the

plant:

All machine and plant parts (control cabinet / control cabinet doors / installation panel / cooling rear panel / PE busbar / cable

duct / machine bed / motor) must be connected with the largest possible contact area and short metallic connections directly or

by means of Cu stranded conductors (low resistance to high frequency, mixed as frequently as possible).

Use metallic bare installation panels and cable ducts.

Contact places must be bare and free of grease. Contact surfaces directly without locking washers etc.

Power and signal cables must be separated consistently from one another (minimum distance < 20cm), if necessary provide

separating plates grounded over a wide area. Cables must cross at right angles and at a distance. Avoid conductor loops and

run the cables as close as possible to the reference potential PE (housing wall, metallic cable duct). Unused conductors must be

PDK_028932_KEKW_Hardware_en

page20

grounded. Cable shields must be connected always directly to housing inputs through flat shield clamps, EMC-suitable cable

screw unions or metal clamps. Shield connections through stub lines are not permitted.

Keep cables subject to interference (motor cables, power cables, clocked current cables) as short as possible, connect the

cable shield always at both ends to the reference potential PE. For sensitive process, control and sensor cables use twisted pair

cables with close mesh Cu shield braiding.

Improve the EMC properties selectively by skilful placing of control units and sensor modules as well as spatial separation for

modules with power electronics (inverters, power supplies, inductances, switching elements) and suitable cable running.

Install line filters flatly on the same installation plate closely against the device to be interference suppressed. Keep the

interference-affected “Load filter” to the inverter short. Run the interference-suppressed power cable (line filter) directly at the

filter input through the control cabinet wall. If no sufficient spatial separation (20cm) between the interference-suppressed power

cable and the cable of the filter load side and other interference-affected cables or components (motor cable, line reactor,

contactors) is possible, use a shielded cable with shield grounded at both ends for the cable from the filter to the inverter and

under certain circumstances also shield the power cable in its run up to the control cabinet output (shield grounded at both

ends).

Switched inductances (contactors, solenoid valves) must be connected with interference suppression elements.

4.3 EMC filters

Because of the circuit principle frequency inverters generate radio interference voltages. The conducted interference levels are

limited to the legally permitted maximum values by radio interference suppression filters. The optimum effect of these filters is

achieved only by EMC-suitable installation, cabling, grounding and shielding. These filters are integrated in the KE 10, KEN

10,KE 20 and KE 40 units. The filter must be installed externally for the units with greater output. Refer to the wiring chapter for

connection and wiring. (see Line filter on page 88 )
