Setup and installation
7.5 Electrical connection
1.
Connect the plug to the power supply.
2.
Switch on and let the machine run briefly.
3.
While the motor is running, check its direction of
rotation.
4.
Should a change in the direction of rotation be nec-
essary, switch the two phases on the power cable.
Electrical connection requirements
• The machine must be earthed with electrical
conductors.
• The voltage fluctuations in the mains supply may not
exceed ±10 %.
• The switch cabinet must be fitted with a circuit
breaker (DIN VDE 0641).
Number of terminals: 3 (three phase current motors)
• The unit must only be used in TN-Systems (neutral
connected to earth)! (only 3x400V)
• Power supply cable H07RN-F at least 5x 2,5 (rotary-
current motor) or 3x 2,5 (alternating-current motor).
• Safeguarding/Power supply cord:
see “Technical data”
• The power supply cable must be protected against
damage (e.g. armoured conduit).
• The power supply cable must be laid in such a way
so it does not overbend or chafe and there is no risk
of tripping over it.
Note: Do not open the machine‘s switch box unless you have the express consent of the Hammer service de-
partment Violating this stipulation shall render the right to make claims under the warranty null and void.
Attention! Risk of material damage!
The machine must be secured with an automatic fuse
Attention! Risk of material damage!
Before hooking up the machine to the power supply, compare the specifications on the data plate with those
of the electrical network. Only hook up the machine if the two sets of data correspond to each other. The
electrical outlet must have the appropriate socket (for a three-phase alternating current motor, CEE).
Warning! Danger! Electric current!
Work on electrical fittings may only be carried out by qualified personnel and in strict observance of the safe-
ty instructions.
Checking the loop impedance and the suitability of the overcurrent protective device must take place at the
location where the machine is to be commissioned!
Note: The machine‘s power cable is delivered with an open cable end, i.e. without a plug.
The operator is responsible for fitting the machine‘s power cable with a suitable plug in accordance with any
country’s specific regulations.
