ELECTRICAL INSTRUCTIONS
The DFG280 machine is supplied with a specially commissioned 110V electric motor and
starter switch assembly. Each unit is fully tested and the safety overload relays have been
calibrated and set according to the manufacturers specifications. In the event of the malfunction
on a new machine the owner should first check that the power supply on site is suitable and
adequate.
DFG280-5
(110V)
•
The
110V
motor requires a 32 Amp supply.
•
To avoid voltage drop the cable size must be a minimum of 4.0mm 3 core. Maximum
length of cable not to exceed 30 metres.
•
If a transformer is used it must have a continuous rated output of at least 3 KVA. In
practice this means that a 5 KVA transformer must be used.
DFG280-1
(415V Three Phase)
DFG280-3 (
230V Single Phase)
•
The
230V/400V
require a 16 Amp supply.
DFG280-6
(115V)
•
The
115V
motor requires a 15 Amp supply.
All cables should be fully uncoiled and never left wrapped around cable reels or tied in loops.
If the power is to be generated, the DFG280 requires a minimum 8kva generator.
The motor is protected with a safety trip in the panel. Should the trip be activated, it will reset
automatically after cooling down.
If the motor repeatedly cuts out then it will be damaged. The possible causes are
either an inadequate power supply, overloading of the machine, or an electrical fault.
