4 OPERATION AND MAINTENANCE
4.1 GETTING STARTED
1.- Before starting the job, check the correct working of all handling and safety devices
2.- Inspect regularly the good conditions of the feeding cables. If is necessary change the cord,
check section Extension cables.
3.- Inspect regularly the connection voltage.
4.- The converter should only be used in conjunction with all safety elements.
5.- Check the screws
6.- If defects are found in the safety devices or other defects which could reduce the safe handling of
the equipment, notify immediately the proper responsible person.
4.2 VIBRATING POKER CONNECTION TO THE CONVERTERS
The converter has a socket to connect the vibrating pokers. Turn off the stylus switch before
connecting the plug to the converter. Always turn on the converter before turning on the needles.
Connection possibilities:
The input current of the pokers connected in load shall not exceed the out current specified in the
electrical characteristic table from converter.
4.3 CONVERTER CONNECTION TO THE SYSTEM
Check the converter switch is off before connecting to the system.
Unless otherwise stated at the time of ordering, the frequency converters three phase will be
connected at the factory as three phase, 400V 50 Hz. The models single phase, will go out of the
factory to be used as 230V 50 Hz single phase charge.
Disconnecting the equipment:
First, stop the vibrating pokers by turning off the proper switch, second stop the converter by turning
off the proper switch, and finally remove the feeding cable from the system.
Earth connection.
To protect the user from an electrical shock, the converter should be correctly connected to earth.
The converters are equipped with three cables (single phase) or four cables (three phase) and their
respective plugs. The adequate earth socket should be used to connect the converters. If the socket
with earth is not available, an earth adapter should be used before connecting the plugs.
Extension cables.
Always use extension cables with earth wire and its respective plug with earth in the female and
male plug.
Do not use damaged or worn out cables.
Avoid heavy loads on cables.
To determine the transversal section, follow the following procedure:
PROCEDURE TO DETERMINE THE NECESSARY TRANSVERSAL SECTION IN CABLE
EXTENSION
Do the following verifications and take the highest section of cable:
1. The ohmic resistance and inductive resistance of the cable with the permitted loss of voltage of 5%,
cosphi=0.8 trough the frequency and voltage curve
