 Electric Field Strength (Electric Wave Condition)

For the proper and stable operation of this system, the eld electric strength of the location for the

equipment should be controlled as following:

10 V/m or less (26 MHz to 1.0 GHz)

10 V/m or less (1.4 to 2.0 GHz)

1 V/m or less (2.0 to 2.7 GHz)

In case of the usage of wireless equipment such as transceiver nearby this system, note as
following:

• The door of this system should be closed.

• In case of the usage of transceiver with 10 W or less, the distance from this system should

be kept 1 m or more.

• As for the usage of wireless equipment with 1 W or less such as mobile-telephone, PHS,
wireless telephone or LAN equipment, the distance should be kept 1 m or more. Attention

should be paid to the micro wave radiated from mobile-telephone or PHS even out of usage.

Following formula represents the electric eld strength. However, the calculated value requests

ideal environment. Worse conditioned environment should be taken into consideration. In case
some wireless equipment is used nearby this system, this formula would be useless. The value
calculated through this formula should be considered noting other than reference.

1.3 Power Supply System

The following conditions should be met:

• Voltage and frequency uctuations are within the limits specied for each system

component.

• Waveform distortion is within limits.

• High-frequency noise is not at a level that affects system operation.

• Use an UPS (uninterruptible power supply) if necessary.

 AC Power Specication

AC power used for the system must be within the specied rated voltage and the peak value
must be greater than the minimum specied (see below). DC power must be within 24 V DC

-10%/+20% at the power supply terminals.

IMPORTANT

If the power unit has high output impedance or high wiring impedance, the resulting voltage drop

attens the input voltage wave, forming a distorted waveform with a low peak value (“B” in the

chart below).

1-11

Even if the effective value of the distorted input voltage wave is the same as that specied for a

non-distorted input voltage wave, the voltage across the terminals of the smoothing capacitor
in the power circuit may be so low that the system detects power failure. Even if input voltage

waves A and B shown below have the same effective value of 100 V AC, wave B will have a

lower smoothing capacitor terminal voltage.

The DC stabilized power supply for the ProSafe-RS (except PCs) uses a compact and efcient

switching regulator circuit. In this circuit, output voltage cannot be maintained if the energy
(terminal potential) of the smoothing capacitor falls below a predetermined value. The circuit
monitors the capacitor terminal voltage and regards it as power failure if the voltage falls in the
danger zone, causing the system to enter power fail mode (non-detected momentary power
failure: up to 20 ms).

Current ows to the capacitor in this circuit when AC input voltage is higher than the capacitor

terminal voltage. Since the capacitor is charged by the peak value of the input waveform, it is

required that both the effective voltage value and the peak value conform to the specication

requirements.

1. System Installation Requirements

 Selecting a Power System

The ProSafe-RS system requires a power supply that satises power requirements in

accordance with EMC regulations. It is recommended that an external power supply unit be
used in order to prevent disruptions due to momentary or extended power failure, line noise, or
lightening surges, as well as to suppress harmonic current from various devices.

For selection of the power supply unit, consult with a power unit manufacturer taking the following
points into consideration.

 Source Output Capacity

Take the following items into consideration when consulting with a power unit manufacturer to
determine the output capacity.

Power consumption: Both volt-ampere and watt data should be studied.

Device crest factor: Ratio of the peak value to the effective value of the device input

current.

Device in-rush current: The method of turning on the power should also be studied.

Backup ready time after failure: Time period required to backup the devices when power fails.

Reserve capacity: An extra power capacity should be determined as reserve to

meet any device additions.

Crest factor =

Peak value

Peak value

Effective value

Crest factor = Peak value of device input current / Effective value of device input current

The crest factor must be considered for the input current supplied to every device connected to
the system when estimating the power output capacity in selecting the power unit.

Approximate device crest factors should be as follows:

100-120 V supply voltage: Crest factor About 3.

220-240 V supply voltage: Crest factor About 6.

 Common Method to Determine Power Unit Capacity

The following shows the commonly used method used to determine the power unit capacity

taking the crest factor into consideration - the nal determination should be made in consultation

with a power unit manufacturer:

• If the specication of power unit crest factor (the peak current value allowable for the

effective current value) is larger than the above device crest factor, the power unit can be
used for up to full rated capacity. However, in-rush current, backup time, reserve capacity,
etc., must be separately taken into consideration.

• If the power unit crest factor is smaller than the device crest factor, the power unit capacity

needs to be calculated in the expression shown below. In-rush current, backup time, reserve
capacity, etc., must be separately taken into consideration.

Power unit output capacity = Total device power consumption x Capacity coefcient

Capacity coefcient = Device crest factor / Power unit crest factor specication

TI 32S01J10-01E

Jun.18,2008-01

1. System Installation Requirements

 In-Rush Current

When the equipment is turned on, a large in-rush current ows as the capacitor is

instantaneously charged and the transformer is excited. When any equipment is turned on, this

should not cause any voltage uctuation that could adversely affect other equipment. Do not turn

on all equipment at the same time. Start equipment one by one.
Power may be switched to backup or AC line power if in-rush current activates the overload

protection circuit on power-up. After such an overload, select an uninterruptible power unit, with
automatic-recovery.

 Suppressing Harmonic Current

In order to suppress harmonic current supplied to a low-voltage distribution system, it is
necessary to install a power unit or an active harmonic suppressor, such as indicated below,
between a device and the distribution system:

• Power unit equipped with the harmonic suppression function (a high power-factor inverter-

type uninterruptible power unit, etc.)

• Active harmonic suppressor

In Europe, a power unit should be selected so that harmonic current emissions are within the

limits specied by EMC regulations.

The capacity of the harmonic suppression unit should be determined in consultation with a power
unit manufacturer in the same manner as the selection of power unit’s output capacity previously
discussed.

1-15

 Cabling

Observe the following when cabling the power unit to the ProSafe-RS system equipment:

• Protect signal cables from induced noise.

• Protect signal cables from induction from high-voltage power lines.

• Separate the ProSafe-RS system power supply from other equipment power supplies.

• Provide a dedicated breaker for each power supply.

• Install breakers and devices in the same room.

• Label the breakers with the name of the connected equipment.

• Install the breakers where they can be easily operated.

• The breaker, must not interrupt connection by wiring to protective grounding system.

• As far as possible install power supply cables and high-voltage power lines in metallic

• Use shielded cables if metallic conduits cannot be provided.

Use a separate power distribution board.

1.4 Grounding

To avoid electric shocks and minimize the inuences of external noise, the installed
devices must be grounded to the protective grounding system which complies with the
safety standards, the electrical installations standard, and the power distribution system
of the country or the region.

As for the protective grounding systems, the meshed grounding systems described in
IEC 60364, IEC 62305 and IEC 61000-5-2 can be applied.

A protective device is to be installed in compliance with the rules and regulations, in order
to prevent electric shocks caused by a ground fault.

A plug type power cable has to be connected to the receptacle connected to the protective

grounding system.

 Grounding Circuit

Grounding examples are given below.
If ProSafe-RS systems are housed in a cabinet, the cabinet must be grounded according to the

grounding network topology of the building or plant for installation.
In order to connect a cabinet with a protective grounding system, the grounding topology shown

in the gures “Grounding connected to a single grounding bus inlet” or “Grounding connected to
each grounding bus inlet” can be used.

When providing lightning arresters on power and signal lines, those arresters need to be

grounded to the same bus. For details, see Section 1.5, “Noise Countermeasures.”

 Grounding with Other System

Do not connect ProSafe-RS’s cabinet with other system cabinets or consoles electrically using

bolts or other connection mechanism in order to avoid unexpected electrical connection or
interference.

When ProSafe-RS is joining side by side with other system cabinets or consoles, ensure to insert

insulating sheets.

The cabinets or consoles other than ProSafe-RS must be insulated from a oor and connect it to

a protective grounding system using a different grounding cable.
