4. Use only intact cut-off wheels or cup wheels. The cut-off wheels and

cup wheels must be approved for min. 5000 rpm. If other cut-off

wheels, saw blades or cup wheels are used, make sure that the speed

setting of Accutom-50 complies with the max. speed for the cut-off

wheels, saw blades or cup wheels.

5. Observe the current safety regulations for handling, mixing, filling,

emptying and disposal of the additive for cooling fluid.

6. The sample must be securely fixed in the specimen holder.

7. Do not touch the sample, the specimen holder head, the cut-off wheel

or cup wheel while positioning the sample with the POSITION controls.

8. Never try to open the cover before the cut-off wheel or cup wheel has

stopped completely.

The equipment should only be used for its intended purpose and as detailed in the Instruction Manual.

The equipment is designed for use with consumables supplied by Struers. If subjected to misuse, improper

Supplying Power

DANGER!

The machine must be earthed

IMPORTANT

Check that the mains voltage corresponds to the voltage stated

on the type plate on the back of the machine.

Changing the voltage setting

If the factory setting is not the correct setting for your mains supply the

setting can be changed from 240V to 220V:

Accutom-50

Instruction Manual

Accutom-50 is shipped with 2 types of Mains cables:

The 2-pin (European Schuko) plug is for use on single-phase

connections.

If the plug supplied on this cable is not approved in your country,

then the plug must be replaced with an approved plug. The leads

must be connected as follows:

Yellow/green: earth

Brown: line (live)

Blue: neutral

The 3-pin (North American NEMA) plug is for use on 3-phase power

connections.

If the plug supplied on this cable is not approved in your country,

then the plug must be replaced with an approved plug. The leads

must be connected as follows:

Green: earth

Black: line (live)

White: line (live)

Both cables are on the other end equipped with an IEC 320 cable

connector that has to be connected to the Accutom.

Single-phase Supply

3-phase Supply

Connection to the Machine

WARNING!

The output voltage from this cable is 200 – 240V and not 110V.

DO NOT use this cable to connect equipment that use a 110V power

supply. Failure to adhere to this may result in material damage.

Recirculation Unit

IMPORTANT

Always ensure that there is sufficient water in the tank as the recirculation

pump will be damaged if it is running dry.

Note:

Changing of cooling water should be done at least once a month.

IMPORTANT

Always maintain the correct concentration of Struers Additive in the cooling

water (percentage stated on the container of the Additive). Remember to

add Struers Additive each time you refill with water.

Do not use any oil, petrol, or turpentine-based additives, only Struers

additive.
