•
Fluctuation along the circuit line should be less than 5%. If this is
exceeded, the fuse will blow, which is located in the power socket and
accessible from the exterior.
•
Do not connect this device to standard extension cords or power strips.
•
The powerful laser is extremely high voltage and potentially dangerous,
so users must securely ground the engraver to avoid the buildup of static
electricity.
•
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.
4.6 Setting up the Control System
1. Turn the beam attenuator fully clockwise.
2. Plug in the interlock connector.
3. Confirm the power switch is in the O position before setting up the control system.
4. Confirm that the voltage on the label above the laser’s power socket matches your local power
supply. And plug the engraver into a grounded outlet or into a surge protector rated over 2000 J
that is itself connected to a grounded outlet. Use a dedicated circuit with no other devices on it.
If the outlet is not grounded, use a grounding cable (not included) and connect it as follows:
a. Fasten the near end of the grounding cable to the grounding port at the back of the
engraver.
b. Connect the far end of the cable to a single metal rod driven at least 8 feet (2.5 m) deep or
to two separate metal rods driven at least 4 feet (1.2 m) deep into soil located at least 5 feet
(1.5 m) from the machine.
