4. Ground rod to be connected to ground terminal in control enclosure using insulated 8-gauge stranded copper
wire.
5. An additional point to check is ensuring continuity of ground within control enclosure. Start with main power
entrance ground terminal where internal ground conductors should originate and connect to, DIN terminal strip,
control transformer and the lid of control enclosure. Also PLC and Interface units should have their own ground
conductors connected to one of the main ground terminals.
6. Properly functioning ground system will;
•
Provide safety for personnel.
•
Ensure correct operation of electrical/electronic devices.
•
Prevent damage to electrical/electronic apparatus.
•
Help dissipate lightning strokes.
•
Divert stray radio frequency (RF) energy from electronic/control equipment.
WIRING CONNECTIONS
After the machine is leveled 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 are 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.
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 box with the Ll, L2,L3 and Ground terminals. The dis-
connect box is located at the drive side of the machine.
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 counterclockwise direction. If the hydraulics do not
register an immediate pressure rise,
- shut the hydraulics off and change the phase order.
HYDRAULIC OIL AND CUTTING FLUID
As shipped the saw oil tank is filled with Arco - Duro AW46 hydraulic oil. If you want to change the hydraulic oil or the
brand of oil, see HYDRAULIC MAINTENANCE.
No cutting fluid is supplied with the machine. There are two types of coolant available:
•
oil based; dilute in 1:10 ratio (one part of concentrated coolant and 10 parts of water)
•
-synthetic; dilute as recommended by manufacturer.
