Power Requirements

The following sections specify power requirements for the print engines, the printer control unit, and the Air Bearing Buffer/Flipper Unit (if installed).

Power Outlet and Cable Summary

You should plan for one or more outlets, as summarized below.

Plan for cable lengths when doing your space planning. Figure 26 shows cable lengths for the print engine power cable and the printer control unit power cable.

Print Engine Power Cable and Receptacle

All Countries Except the U.S.A. and Canada (All Models)

The print engine power cable is supplied without a plug. Provide the appropriate plug and compatible receptacle.

Understand the electrical standards for your country, and use only an approved plug. Your marketing representative has information on the voltage requirements in your country.

U.S.A. and Canada (Models MS1, HS2, MD1/2, HD3/4, TS1, and TD1/2)

InfoPrint 4100 Models MS1, HS2, MD1/2, HD3/4, TS1, and TD1/2 use cords with Hubbell plugs. Provide either of the following Hubbell connector or receptacle (or equivalent) for this plug:

Connector (inline)
Receptacle (mounts on a wall or rail)

Figure 27 shows a Hubbell cord, plug, and receptacle.

Positions for phase connectors R1, S2, T3, and ground (G) are shown. An angle back box may be used in conjunction with the receptacle.

These parts are available through Hubbell even though the part numbers shown may not be a standard item listed in their catalog.
U.S.A. and Canada (Models HS3, HD5/6, TS2, and TD3/4)

InfoPrint 4100 Models HS3, HD5/6, TS2, and TD3/4 use cords with Russellstoll plugs. Provide either of the following Russellstoll connector or receptacle (or equivalent) for this plug:

Connector (inline)
Receptacle (mounts on a wall or rail)
These parts are available through Russellstoll or their distributors.

Figure 28 shows a Russellstoll cord, plug, and receptacle.

Physical installation Power and Grounding Recommendations

Consult electrical authorities to ensure compliance with local electrical code.
Power recommendations

De-rate facility step-down transformers 50% to handle surge currents and harmonic currents. Assume that the transformer's neutral connection (400V installations) will see two times (2X) the current of any of the phases.

The transformer neutral connection is bonded to earth. Ensure that (1) the connection between earth and transformer is secure, (2) that the grounding rods are in good condition and in good contact with earth, and (3) that the connection distance is the shortest path possible.

To minimize interference between devices in the printing room, separate step-down transformers may be used to feed separate groups of equipment. However, this is not always feasible. To reduce interference, install the transformers as close as possible to the distribution panel and, from the panel, feed every device with its own separate power cord (L1, L2, L3, (N,) E). This will ensure the shortest length of common (shared) wiring.

The power cord neutral wire must be at least as large as the line (phase) wires.

To best balance the loading on the phases of the transformer when more than one printer engine is installed, the line (phase) wires (but not neutral wire) to the printers may be rotated. See Figure 29.

If more than one printer is installed, the power line wires may be rotated to balance the transformer phase loading. In high voltage regions (400V), a neutral wire is present, but is not rotated.

Grounding recommendations
Auxiliary power source recommendations

The InfoPrint printers are designed to tolerate loss of power without damage. Therefore, backup power sources such as UPS units or other electronic power supplies are not necessary.

The dynamic power consumption of laser printers must be understood if a backup power source is being considered.

  1. Startup power, and current, might exceed five times (5X) the continuous, or average, power. This is highly dependent on the impedance of the facility's distribution system and power source. This surge of power lasts only a few cycles of AC and rapidly falls to its nominal level.
  2. While printing, there are regular changes in current loading as lamps and heaters cycle on and off, and this intermittent, instantaneous power might exceed two times (2X) the average power.
  3. The continuous, or average, power is specified in the following sections.

Therefore, the selection of an auxiliary power source must involve careful consideration of these aspects of power consumption, and it is recommended that the manufacturer of such equipment understand these power requirements.

Additional electrical requirements for 50Hz 400 V installations
The following statements apply to InfoPrint 4100 models MS1, MD1/2, HS2, HD3/4, HS3, HD5/6, TS1, TD1/2, TS2, and TD3/4.

In addition to the electrical requirements defined in Table 15, Table 20, and Table 23, the following are minimum requirements for service current capacity and short circuit ratio:

Service current capacity (Iscc)
75 amps minimum for duplex models 50 amps minimum for simplex models
Short circuit ratio (Rsce)
150 minimum
Refer to Glossary for definitions of these terms.
Interface point Requirements for low frequency phenomena

EN 61000-3-11 Compliance Statement: This equipment complies with EN 61000-3-11 provided that Zmax is less than or equal to 0.05 ohms at the interface point between the user's supply and the public network. It is the user's responsibility to ensure the equipment is connected only to a supply of that impedance or less. The user may consult with the electrical utility, if necessary, to determine the network impedance.

Common Electrical Requirements

Ensure that you have electrical outlets that meet the power requirements for your printer. These outlets must be able to disconnect power from each printer. For example:

Table 15. Basic voltage requirements for the printer
AC Voltages Wiring Information
Nominal Minimum Maximum Printer Engine Control Unit Flipper (duplex models)
U.S.A, Canada 60Hz
3L + PE 2L + PE 2L + PE
Japan 50 or 60Hz
3L + PE 2L + PE 2L + PE
Europe 50Hz
3L + N + PE L + N + PE L + N + PE
The 50-Hz 380/400/415 Volt version does not support non-earthed neutral and impedance-grounded neutral power distribution systems. Installation on an impedance-grounded neutral power system (IT Power System) could result in failures of motors and transformers in the printer.
The current load for InfoPrint 4100 Models HS3, TS2, TD3/4, and HD5/6 is greater than previous InfoPrint 4100 Models, consistent with their higher throughput. Installation of this printer might require that you increase your branch circuit service rating. Consult your local electrical authority to ensure your service is sufficient.
