• Fire prevention
In order to prevent the danger caused by the accumulation of volatile gas, sufficient ventilation must
be provided to ensure that the air vent of the work area is low enough to replace the air for 6 to 8
times every hour, so that the volatile gas cannot accumulate near the floor.
The electrical equipment installed near the working area must comply with GB/T standards and the
provisions of the national electrical regulations on Class I and Class II sites, and shall be installed by
professional electrical contractors with corresponding qualifications. The regulations on hazardous
waste treatment shall comply with the special storage and treatment requirements of relevant
departments.
• improve air circulation
In order to prevent the danger caused by the accumulation of volatile gas, sufficient ventilation must
be provided to ensure that the air in the working area is changed about 6 to 8 times every hour.
The vent shall be low enough to prevent volatile gases from accumulating near the floor.
The electrical equipment installed near the working area must comply with GB/T standards and the
provisions of the national electrical regulations on Class I and Class II sites, and shall be installed by
professional electrical contractors with corresponding qualifications. The regulations on hazardous
waste treatment shall comply with the special storage and treatment requirements of relevant
departments.
• Electrical requirements (UPS and power regulator are highly recommended)
X3E-602/604 uses single-phase power supply, and the printer must be well grounded. (The ground
wire+neutral line voltage shall not be greater than 0.3V, and the grounding resistance shall be less
than 3 Ω.)
The range of power supply voltage is 220V (± 10%), AC 50Hz or 60Hz. The access power supply and the
power supply must match, and the wire diameter of the access wire must meet the rated current
requirements:
The maximum power consumption of the printer is less than 2 kW, and the average power
consumption is 1.5 kW. The UPS can use 3KV15A, which can be connected to computers and
printers.
The maximum power consumption of the fixation machine is less than 5 kW, and the
average power consumption is 3.5 kW. The current rating is required to be 30A.
The main wire connected to the printer and fixation machine shall not be less than 50A, and the
distance from the main power socket to the electrical access end of the equipment shall not be
more than 2m.
• Grounding requirements
Installation and requirements of ground wire: install the ground wire on the public grounding iron
plate in the equipment. Then use a multimeter to switch to the AC 220 V~measuring range. One
meter pin is connected to the ground wire, and the other is connected to the zero line of the AC
input terminal. The measured value is less than 2.
