1. General

The SK 500E series is based on the tried and tested NORD platform. These devices feature a compact design with optimum control characteristics.

These frequency inverters are provided with sensorless vector current control system which in combination with as ynchronous three-ph ase motor types constan tly ensures an optim ised voltage-tofrequency ratio. For the drive unit, this means very hi gh starting and overload torques with constant speed.

As standard, the freque ncy inverters are eq uipped with a fixed heat sink, via whic h the power losses are dissipated to the environment. Altern atively, for sizes 1 - 4 there is the ColdPlate versi on and for sizes 1 and 2 there is also an external heat sink version.

This series of frequenc y inverters can be adapte d to indivi dual requirem ents b y means of t he modular technology units.

Due to the wide range of setting options, these inverters can control all three-phase motors. The power range is from 0.25 kW to 90.0 kW with integrated mains filter.

This manual is base d on the d evice soft ware as state d in the ver sion list (s ee P707). If the frequenc y inverter uses a diff erent s oftw are v ers ion, t his may cause differences. If nec ess ar y, the current manual can be downloaded from the Internet (http://www.nord.com/

There are additional descriptions for the optional functions "Functional Safety "(BU 0530) and the "POSICON" positioning system (BU 0510) and the memory programmable "PLC" control units (BU0550). Supplementary descriptions for the optional bus systems are also available

The equipment requires sufficient ventilation to protect against overheating. For this the minimum guideline distances f rom adjacent components above and below the fr equency inverter, which could obstruct the air flow apply.

Distance from device: Mounting can be immediately next to each other. However, for the use of brake resistances m ounted belo w the f reque ncy inverter (not possib le with … -CP devices), the gre ater width must be taken into consid eration, particularly in combination with temperature switches on the brake resistor!

Installation position: The installatio n positio n is normall y vertical. It must be ensur ed that the coo ling ribs on the rear of the frequency inverter are covered with a flat surface to provide good convection.

(above > 100 mm, below > 100 mm)

Warm air must be vented above the device!

Fig. 3 Mounting distances for SK 5xxE

If several inverters are arranged above each other, it must be ensured that the upper air entry temperature limit is not exceede d. (See also Section 0 ) If this is the cas e, it is recommended that an "obstacle" (e.g. a cab le duct) is m ounted between the inverters so tha t the direct air f low (rising warm air) is impeded.

Heat dissipation: If the frequency inverter is insta lled in a control cabinet, a dequate ventilation m ust be ensured. The heat dissipati on in operation is appr ox. 5% (according to the si ze and equipment of the device) of the rated power of the frequency inverter.

2.1 SK 5xxE, standard version

Normally, the frequency inverter is mounted directly on the rear wall of a control cabinet. For th is, two, or f or sizes 5 to 7, f our matc hing wall m ounting brackets are supplied, which are to be inser ted into the he at sink at the rear of the device. For size 8 and above, the mounting device is integrated.

Alternatively, for si zes 1 ... 4 the wall mounting brackets can be insert ed at the side of the cooling el ement in order to minimis e the necessary depth of the control cabinet.

In general, care m ust be taken that the rear of the cool ing e lement is covered with a flat surface and that the device is mounted vertically. This enables optimum convection, which ensures fault-free operation.

2.2 SK 5xxE…-CP in ColdPlate version

Instead of a cooling element /fan, ColdPlate versions of the frequency inverter have a flat metal plat e on the rear side which is mounted on an existing mounting plate (e.g. the rear wall of the control cabinet) so as to pro v ide t h ermal conduction. A liq ui d c ooling medium (water, o il) may also be passed through the mounting surface. In this way, not only is the waste heat from the frequency inverter dissipated more effectively, but also the waste heat from the inverter is prevented from remaining inside the control cabinet. In addit ion to the optim isation of the p ower reserved and th e service life of the inverter, this also causes less thermal load on the inside of the control cabinet.

A further advantage of the ColdPlate version is the reduced installation d epth of the device and the fact that in general, there is no need for a fan on the frequency inverter.

Bottom-mounted brake resistors (SK BR4-…) cannot be mounted directly.

Alternatively, the EMC Kit can be simply used as a strain relief (e.g. for the connection cables of a bus system)

2.5 EMC Kit

For optimum EMC-compliant wiring, the optional EMC Kit must be used. This includes a shield bracket, two hamm er clips, two fasten ing screws an d a pre-assem bled PE cable. T he PE cable m ust be connected to the appropriate screw on the shielding bracket and to the PE terminal of the frequency inverter. The connection of further PE connections to the shield bracket is possible with additional ring cable lugs (SK EMC 2-1 and 2-2).

The EMC Kit provides th e pos sibi li t y of attaching the screening of the motor cable to a lar g e sur f ac e of the frequency inverter (interference source). If necessary, a screened brake resistor cable can be attached with the second hammer clip.

The screening angle is attached to the two housing screws on the lower edge (below the U-V-W terminals). The m otor cable screening is earthed to a large area of the s creening angle by means of the hammer clip.

2.6 Brake resistor (BR)

CAUTION

Danger of burns

The heat sink and all other metal components can heat up to temperatures above 70°C. Touching such components may cause local burns to the affected parts of the body (hands, fingers, etc.). To prevent such injuries, allow sufficient time for cooling down before starting work - the surface temperature

components during installation, or install protection against contact.

During dynamic brak ing (frequency reduc tion) of a three-phase motor, electrica l energy is retur ned to the inverter. An external br ake resistor can be used in order to prevent the F I from being shut down due to overvoltage. W ith this, the int egrated brake c hopper (electr onic s witch) pul ses the interm ediate circuit voltage (switching wave approx. 420 V/775 V(/825 V) DC, according to the mains voltage) (115 V, 230 V/400 V(/500 V)) to the brake resistor. Here the excess energy is converted into heat.

For inverter powers up to 7.5 kW (230 V: up to 4.0 kW) a standard bottom-mounted resistor (SK BR4-..., IP40) ca n be u s ed. This can additionally be equipped with an opt io na l temperature switch (bi-metal, switching po int 1 00 ℃ is enclosed. The resistor and the temperature switch are connected by means of flexible stranded conductors. Approval: UL, cU L

Note: Brake resistors cannot be directly mounted below …-CP (ColdPlate) devices.

For frequency inverters above 3kW chassis resistors (SK BR2-..., IP20) are also available. These must be mounted i n the cont rol c abinet, close to th e fr equenc y invert er. T here is a tem per ature switch on the braking resistor to provide protection against overload. Connection of the resistor and the temperature switch is by means of screw terminals. Approval: UL, cUL
