Page 34: Assembly And Installation
NORDAC PRO (SK 540E series) – Manual with installation instructions 2 Assembly and installation SK 500E frequency inverters are available in various sizes depending on the output. Attention must be paid to a suitable position when installing. The equipment requires sufficient ventilation to protect against overheating. For this the minimum guideline distances from adjacent components above and below the frequency inverter, which could obstruct the air flow apply.
Page 35: 5Xxe In Standard Version
2 Assembly and installation 2.1 SK 5xxE in standard version Install the frequency inverter directly on the rear wall of a control cabinet. Two wall-mounting brackets (for sizes 5–7: four wall-mounting brackets) are enclosed, which must be inserted into the heat sink on the rear of the device. For size 8 and higher, the mounting device is already integrated.

NORDAC PRO (SK 540E series) – Manual with installation instructions 2.3 External heat sink kit External heat sink technology is an optional supplementation to the cold plate device. It is used when external cooling is required but no liquid- cooled mounting plate is available. A heat sink is mounted on the cold plate devices, which reaches the external, air-cooled environment through a recess in the rear wall of the control cabinet.

Page 51: Chokes
2 Assembly and installation 2.7 Chokes Frequency inverters cause loads both on the mains side and the motor side (e.g. current harmonics, steep flanks, EMC interference), which may result in malfunctions in system operation and in the frequency inverter. Mains or link circuit chokes are primarily used for protection of the mains, motor chokes primarily reduce influences on the motor side.

2 Assembly and installation Sinus encoder (SIN/COS encoder) The use or function of sine encoders is comparable with that for incremental encoders. However, the encoder provides sine wave signals instead of digital pulses. The supply voltage for the encoder is 10-30V. The voltage source can be an external source or the internal voltage (according to the frequency inverter version: 12V /15V /24V).

For approx. 3.5 s, 2x overcurrent is possible. A reduction of the overload capacity or its duration must be considered for the following circumstances: •...
Page 216: Reduced Overcurrent Due To Time
NORDAC PRO (SK 540E series) – Manual with installation instructions 8.4.2 Reduced overcurrent due to time The possible overload capacity changes depending on the duration of an overload. Several values are cited in this table. If one of these limiting values is reached, the frequency inverter must have sufficient time (with low utilisation or without load) in order to regenerate itself.
Page 217: Reduced Overcurrent Due To Output Frequency
8 Additional information 8.4.3 Reduced overcurrent due to output frequency To protect the power unit at low output frequencies (<4.5 Hz) a monitoring system is provided, with which the temperature of the IGBTs (insulated-gate bipolar transistor) due to high current is determined. In order to prevent current being taken off above the limit shown in the diagram, a pulse switch-off (P537) with a variable limit is introduced.
Page 218: Reduced Output Current Due To Low Voltage
NORDAC PRO (SK 540E series) – Manual with installation instructions 8.4.4 Reduced output current due to low voltage The frequency inverters are thermally designed with regard to the rated output currents. For lower low voltages larger currents cannot be used in order to keep the output power constant. For mains voltages above 400 V the permissible output current is reduced inversely proportional to the mains voltage in order to compensate for switching losses.
Page 219: Energy Efficiency Optimisation When Operating Asms
If necessary, provide fall protection (e.g. for lifting equipment) or equivalent protective measures. NORD frequency inverters have a low power consumption and are therefore highly efficient. In addition, with the aid of "Automatic flux optimisation" (Parameter (P219)) the inverter provides a possibility for increasing the overall efficiency of the drive in certain applications (in particular applications with partial load).
