• 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)
Polaroid Second 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.
