POWER WIRING CONNECTIONS (for S-23A with the PLC option)
After the machine is levelled and anchored the necessary power hook-up needs to be performed.
In order to provide a safe operation as well as to prevent potential damage to the machine, only qualified
personnel should be allowed to do the work.
The first two areas that need to be checked are:
- There is no signs of shipping damage to electrical conduits, cords or hydraulic hoses.
- Hydraulic oil level is between the upper and lower lines on the level gauge.
During the initial hook-up it is very important to check that the phase order is correct. This is indicated by the
hydraulic pressure gauge registering a pressure rise and the blade running in a counter clockwise direction. If the
hydraulics do not register an immediate pressure rise,
- SHUT THE POWER OFF -
And change the phase order. As supplied, the machine is set to run on the three phase voltage as indicated on
the serial plate and voltage label. Power connection to the machine is made to the main disconnect switch and the
Ll, L2, L3 and Ground terminals. The disconnect switch box is located on right side of the infeed.
To gain access to the disconnect box, follow these steps:
1) Ensure the switch is in the OFF position and power is diconnected.
2) Push the lockout tab to the right and pull the door open.
To close the door properly, reverse the above steps.
