1.0 General

NORDAC frequency Inverters are sine-related pulse-width modulated inverters with a constant DC link voltage.

The inverters can be used for infinitely variable adjustment of the speeds of 3-phase motors with low loss.

Use:

- For single-motor and multiple-motor drives

Output currents and DC link voltages are detected very

- NORDAC frequency inverters are short-circuit proof,

quickly and precisely.

ground-fault resistant and stable at no load.

The inverters permit 1.5 times the rated current for

- There is no immediate switch-off in the event of overload 30

seconds.

of brief short-circuit

The settings on the NORDAC Frequency Inverter are made with keys and displays in plain language (in dialogue with operater).

Advantages:

- Operating data in digital values

- Precisely reproducible at any time and with any unit of the

same series

- Analogue adjustment facilities no longer present

Separate braking chopper:

- To be used for recovery of high regenerative braking energy

to the DC link

- To be connected to the + and - terminals (even afterwards)

1.1 Delivery

Examine the device immediately after delivery for transport damage such as distortions or loose parts.

If damage has occured:

- Contact the transport company without

delay.

- Make a careful note of damage.

Important! this applies even if the packaging is undamaged.

1.2 Scope of delivery

Standard version :

- IP 20 panel mounting unit

with built-in line choke and output filter for

compensating for line capacitances (see point 10.3)

- Operating instructions

- Output filters (see point 10.4)

Accessoires available:

- Braking chopper

with integrated braking resistor (see point 7)

- Additional choke for higher line capacitances

(see point 10.3)

- Special versions, e.g. for frequencies above 120 Hz

1.3 Installation and operation

Installation :

- Installation by qualified personnel only

- Observe local regulations applicable to installation of

electrical systems

- Adhere to accident prevention regulations

- Take the usual safety measures

Before switching on the unit:

- Re-attach all covers and guards

- Reconnect all plugs (---> push-locked terminal strips)

- Also reconnect all plugs not being used

CAUTION ! DANGER !

=========================

The power section can still be live up to 2 minutes after being disconnected from the mains.

Inverter terminals, motor supply cables, and motor terminals can still be live.

Touching exposed or unconnected terminals, cables, or parts of the device can lead to serious injuries or even death!

Important Note ! Caution !

==============================

Motor stop owing to:

- Electronic disable

* Inverter terminals, motor leadwire, and motor

- Terminal short-circuit

terminals are still live !

- Drive jammed

* The motor may start up on its own if the inverter is not

disconnected from the mains.

The electronic disable facility is not a device as defined by German Accident Prevention Regulations (UVV).

The terminals on the control board are not at mains potential.

2.0 Installation

The units require adequate ventilation. Minimum clearances between the individual units must be observed for this purpose.

The heated air is to be carried off above the devices!
