POWER WIRING CONNECTIONS
When the machine has been anchored and levelled the power hook-up is the last installation step. In order to
provide safe operation and to prevent potential damage to the machine, only qualified personnel should make the
electrical connections.
As supplied your new S-20 Series II is set to run on three phase voltage or single phase. The supply voltage of
the machine is displayed on the Serial # Plate and the Voltage Label.
Connection from the Main supply is made to L1, L2, L3, (or L1 & L2 for single phase) and Ground terminals
between the contactor & transformer.
Supply conductors should be rated for the current supplied and should be protected by time delay fusing rated for
the amperage stated on the machine serial plate
CHECK FOR: - Signs of damage to the electrical cables from shipping or installation.
- Correct phase order. The blade should be running counter clockwise.
(If the blade direction is wrong, two lines should be reversed to correct)
POWER CABLE ROUTING
The main power cable can be routed up through the bottom of the
head frame to the access holes in the end of the control panel. Cable
liquide tight reliefs should be used to secure the cable into the control
panel to ensure there is no movement of the cable when the machine is
operated.
The S-20, with "H" option control panel, opened. L3, L2, L1 and Ground
