General remarks
We urgently recommend reading these Operating Instructions before transporting, installing, configuring or servicing a NORDAC frequency inverter. Each person entrusted with any of the tasks mentioned above is supposed to follow both the Basic Operating Instructions and the instructions contained in the present Supplement. All of the safety information mentioned in the said manual and in the present Supplement must strictly be observed to ensure personal and material protection. Prevention of dangerous situations and damages crucially depends on safety instructions to be taken seriously and to be implemented!
Other provisions and requirements to be taken into account include those applicable on a national and local scale as well as the specific parameters and instructions relating to the technical system of which the inverter will be a part.
Important!
In addition you should by all means be aware of the maximum allowable operating speed and the maximum allowable output torque of the reducer unit. These values are indicated on the reducer´s type plate and must never be exceeded!
Skilled personnel with the proper qualification
It is presumed that all of the transport, assembly, installation, parameterization and maintenance work is performed by technical personnel qualified for their tasks. The term "qualified" is is understood to refer to individuals who, having been properly trained and instructed and on account of their experience and knowledge of relevant standards, accident prevention rules, and the respective operating conditions are qualified to perform the tasks required to set the frequency inverter up for operation. The personnel involved is also supposed to be familiar with First Aid measures and to know how to reach the local rescue services. If the Operating Instructions have got lost for some reason or other, another copy should be obtained from NORD immediately.
Before starting any of the work related to the frequency inverter make sure that the system is in a dead state electrically!

If the frequency inverter is connected to a motor and a speed reducer, also look for the markings showing to which extent motor and reducer are explosion-proof!
Special designs and construction varieties may differ from the standard types regarding certain technical features. If in doubt, by all means contact the manufacturer stating the type designation and the NORD identification number and ask for the required information.
Safety instructions
As the explosion hazard is definitely increased in areas where the air contains inflammable dust, strict adherence to the general safety instructions and to the instructions for system start-up is indispensable. The drive is supposed to meet the requirements specified in Guide No. 6052101 for control process design. If ignited by hot or spark-emitting objects, explosible dust concentrations may cause explosions which may result in grave or even fatal personal injuries and in substantial material damage.
It is absolutely necessary that each person responsible for the use and operation of motors and frequency inverters in hazardous locations is well schooled in how to do this safely in the appropriate fashion.
Always disconnect the supply voltage before you open the frequency inverter to connect the electrical lines or to perform any other work on the device, and protect it against circuit reclosure! Warning! Temperatures inside the frequency inverter and the motor may occasionally exceed the maximum allowable surface temperature of the housing. That is why the frequency inverter must never be opened or detached from the motor while it is surrounded by an atmosphere which contains explosible dust! Check the inverter for dust deposits regularly. When there is more dust than allowed, heat from the inverter can no longer be carried off as effectively as required! If there is doubt about whether the inverter is still performing reliably, the motor needs to be stopped ! Always to ensure dust protection of the motor as well is immensely important with regard to explosion protection.
Repairs on the frequency inverter must not be performed by any other party but NORD as the manufacturer.

The I²t setting 1 for over current control of the motor is imperative.
Instructions for parameterization / Scope of application
As the marking shows, the frequency inverter and the motor are suitable for use in zone 22 (non-conductive dust).
The marking is as follows: For zone 2 operation of frequency and motor, cable entries must ensure at least the IP 55 type of protection. Openings which are not in use have to be sealed with dummy plugs (minimum type of protection IP 55).
The frequency inverter ensures protection of the motor against overheating by evaluating the PTC resistor of the motor. For this effect to be obtained, digital input 1 must be assigned the "PTC resistor" function (P420 = 13). Be sure, too, to select the NORD motor you are using from the motor list (P200). When a motor from a different manufacturer is used the motor parameter data (requested to be set in P201 to P208) must be copied from the type plate of the motor. Best verify whether the settings of the respective parameters correspond with the type plate before starting the motor. Furthermore the frequency inverter should be parameterized so as to prevent the motor from running at a speed greater than 3000 1/
. For a four-pole motor the ´maximum
min
frequency´ should be set to a value less than or equal to 100 Hz (P105 ≤ 100). When you make this setting don´t forget to take the maximum allowable output speed of the gearbox into account!!! Also activate the "I²t motor“ control in parameter P535.

Set point potentiometer
The category-3D SK 300E inverter can be equipped with a potentiometer meeting ATEX standards which can be used to vary the set point (e.g. the speed) on the device.
Designation: Potentiometer ATEX22 - SK 300E Part number: 075142000
The selected set point can be adjusted with a screwdriver. As far as the potentiometer is concerned, it will meet ATEX requirements due to a sealing cap which can be screwed on. For continuous operation the sealing cap must remain fixed.
Technical data:
Resistance value of the potentiometer: 10 kilo-ohms
For a potentiometer to be used with the SK 300E frequency inverter, the device must always be equipped with a customer interface (Basic I/O or Standard I/O)! Typical assignments of the Basic I/O module terminals:
