Printer Electrical Configuration - HP Jet Fusion 4200 Product Documentation Site Preparation Manual

Air extraction should be switched on before starting a build (including checks before printing) and switched
●
off after completely finishing it (once the printer reaches the Standby situation). If the extractor is not
switched off at the end of the job, it will be constantly removing air from the room, which has probably
been conditioned (heated or cooled), which represents unnecessary energy consumption.
Ensure that the cooling system calibration (before or after the job) is performed in the same conditions as
●
printing.
To avoid condensation inside exhaust ducts, thermal insulation must be provided. Condensation appears
●
mainly from agent components (water, solvents, and so on).
If you are installing multiple printers, the above conditions are applicable to each of them. An individual
●
duct system is required to extract air from each printer to the outside of the building. Individual fan and
valve sets towards a common collector system may be acceptable if pressure conditions can be kept
steady in the printer collectors, even with a variable number of printers running or idle. For that purpose, an
extraction system with controlled internal pressure can be helpful.
Position hoods over cooling tower outputs, making use of their referencing lids. In this way, the collecting
●
area will completely cover the grid area.
You are recommended to have an anemometer in the range 0.5–20 m/s, with an error of +-2%, to check
●
that correct aspiration conditions are obtained in each collector.
Flow values are considered at sea level. Increase about 10% for every 1000 m (3281 ft) in height.
●
● When more than one printer is installed in the same room, check the following diagram of air inputs and
outputs to place the printers so that hot air output does not pass directly into an air inlet.

Printer electrical configuration

NOTE: An electrician is required for the setup and configuration of the building electrical system used to power
the printer, and also for printer installation. Make sure that your electrician is appropriately certified according to
local regulations and supplied with all the information regarding the electrical configuration.
The printer requires the following electrical components to be supplied and installed by the customer, according
to the Electrical Code requirements of the local jurisdiction of the country of installation.
Power Distribution Unit (PDU) with three-phase branch circuit breaker
●
NOTE: Remember that you are required to follow the local laws, regulations, and standards that apply to the
electrical installation of your printer.
