SPECIFIC DANGERS
Electrical Energy
In the D-Series laser marking system, the maximum operating voltage is the
connected mains voltage, which can pose a hazard to health. The mains
voltage to be maintained is shown on the name plate.
Work on live components must only be performed by authorised personnel.
In the case of a defective power supply, operation of the laser marking
system is to be stopped immediately and is only to be repaired by
authorised personnel.
Keep the control unit closed at all times. Only expressly authorised
personnel are permitted to open the control unit.
Compressed Air
The laser print head is cooled by compressed air (D120i IP65, D320i IP65).
Air overpressure inside the laser print head is harmful and may lead to
rupture of the cabinet.
The maximum pressure for the compressed air supplied into the print head
is 4 bar. A pressure supply of 4 bar must not be exceeded at any time. The
compressed air has to be free of oil, Class 1.7.2 of ISO8573.
The laser print head has two air outlets. Both air outlets must be kept clear
as blocked air outlets can cause an overpressure inside the cabinet and
may lead to rupture (potential hazard). Please do not swap air inlet and
outlet.
The outer diameter of the outlet hose must be 12 mm. The length of the
compressed air outlet hose must not exceed 4 metres!
Note: Contact Domino before disconnecting the silencer or
connecting a hose to the air outlet 2 at the laser.. If two hoses
are used for the compressed air outlet these have to be placed
in different positions for safety reasons.One event must not
block both hoses.
Water Cooling
Handle the glycol based coolant with care. For more details see the safety
data sheet of the coolant.
As a guide, avoid skin contact with the coolant. Always wear protective
gloves and safety goggles when working with the coolant.
In case of:
• skin contact - remove the coolant by washing with water.
• eye contact - remove by washing with water and seek medical help
immediately.
• swallowing - seek medical help immediately.
