3.5 Main Power Connection
Confirm that the voltage on the label above the laser’s power socket matches your local power supply. Insert
the interlock connection and power cord into their sockets on the rear side of the machine. (If the interlock
connection does not fit, pull back its outer casing, align its holes with the pins, and try again.) Connect the
other end of the power cord directly to a grounded outlet or to a surge protector rated over 2000J that is
itself connected to a grounded outlet. Do not connect the other end to any standard extension cord, power
strip, or ungrounded adapter. For best results, have a trained technician verify that your power supply has
less than 5% fluctuation and that your outlet is properly grounded with less than 5Ω resistance along the
line.
Poor grounding WILL cause equipment failure and create a serious electrical shock hazard. The
manufacturer and/or seller bear(s) no responsibility and assume(s) no liability for any damage,
accidents, or injuries caused by bad grounding connections.
3.6 Cooling System Inspection
Open the cover and confirm that the plastic tank to the right of your main bay is full. The integrated water
pump should arrive with about 1.6 quarts (1.5L) of OMTech coolant already in place. This should not require
replacement during the first year of service, but refill it if the tank ever seems below two-thirds full before
activation.
Flip the engraver’s main power switch and confirm that the coolant begins to flow out of its tank, through
the laser tube, and back into the tank.
NEVER operate your engraver if the cooling system is not functioning properly.
3.7 Air Assist Inspection
Your air assist should also arrive preinstalled and correctly wired. Confirm that pressurized air begins to blow
from the laser head when the engraver is connected to power and turned on.
If any tubing or wiring needs to be adjusted or reconnected, turn off the machine and disconnect it
from power before making any such adjustment.
3.8 Control Computer Connection
Your computer comes with a copy of Ruida Technology’s RDWorks software and a digital copy of its official
instruction manual, both located on the USB flash disk provided with the other accessories. You can also
download a free copy of the most recent version of RDWorks from our website at www.omtechlaser.com/
pages/software-download or from Ruida’s own website at www.rdacs.com/en. See the software manual
for details on the requirements for the control computer.
To configure your control computer and software for the Polar 350,
1. Connect your computer to the engraver using the provided Ethernet cable or one of the provided USB
cables. Use the other USB cable to connect your computer to the port marked “Camera”.
2. Connect the USB flash drive to a third port or to a USB hub connected to your computer. Alternatively,
move all of its files to a folder on your computer.
