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
Entering the curve with the product: =10x150=1500 Am We obtain a 2.5 mm

Section mm
2.
The permitted heating of the cable according to VDE standard ( minimum transversal section table
required).
en
Therefore, the section chosen is equal to 2.5 mm
verifications.
4.6 INSPECTION
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.
3.
Inspect regularly the connection voltage.
4.
The converter should only be used in conjunction with all safety elements.
5.
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.
4.7 PERIODIC MAINTENANCE
1.
Only an expert shall work on the electrical parts.
2.
Make sure that the current is off during repairs.
3.
In all maintenance operations, original parts will be used.
4.
For changing the cord, look at the spare parts, the earth wire (green-yellow) should be longer to
avoid being the first one in cutting in case of breaking wires. If the earth wire is broken, there is
electrical After maintenance, control the earth cable. Put in new cable gland. Tighten its nut.
5.
For changing the switch, look the spare parts, put the seals and finally, tighten the bolts.
6.
Every 24 months or 500 hours of working a lubrication of the bearings of the vibrating pokers is
recommended. An expert should dismantle the vibrating poker. Clean with solvent the bearings and
when this is dry fill in with the oil recommended (107512 spare part). If you note an excessive play in
the bearings proceed to change it. When you reassemble place the sealant in all the threads (PTFE
