Introduction What Equipment Needs Power Conditioning?

What Equipment Needs Power

Conditioning?

Only your electronic based equipment requires conditioned power. Fans, air conditioners and motors do not require power conditioning. Placing fans, air conditioners, motors or other noise generators between the conditioner and the electronics introduces electrical interference into the already conditioned power. In order to minimize electrical noise, each piece of equipment should be individually wired back to the output of the power conditioner.

Sizing Information

The rating label of your ONEAC CDR45I Series Power Conditioner lists the model’s current rating, nominal input and output voltage and serial number. The combined steady state RMS current draw of all your equipment must not exceed the power conditioner's output current rating on any of the three phases.

Your ONEAC CDR45I Series Power Conditioner can operate even with a 100% unbalanced load.

Operating Environment

Clean room The ONEAC CDR45I Series Power Conditioner is intended for operation in a clean room environment. Note that the conditioner incorporates two fans for air circulation. These fans must not be impeded to maintain full circulation. The finish on the conditioner is selected for minimum dusting.

Audible noise The ONEAC CDR45I Series Power Conditioner produces less than 45 dBA of audible noise measured at a distance of one meter from the center of the front door.

Installation

Principle of Operation

The following brief description of the ONEAC CDR45I Series Power

Conditioner’s principle of operation is provided to assist in the proper installation and operation of your power conditioner.

Interconnections and Operations:

1. AC power is supplied to the power conditioner by connection to the input terminal block. When AC power is supplied to this terminal block via the service panel circuit breaker, the Input Power ON LED is illuminated.

2. Three phase AC power is connected from the terminal block to the main input circuit breaker. The input circuit breaker for this product utilizes modular current trip rating plugs which are inserted or plugged into a single molded case circuit breaker frame. An undervoltage release accessory is installed in the input breaker as a means of control.

3. A separate multi-tapped primary, 24 Vac secondary, transformer is utilized for power control, and supplied from the input terminal block (L1 and L2).

The primaries of this transformer are fuse protected (2A, 600 V rating). The secondary of this transformer is also fuse protected (1A, 250 V rating).

4. The 24 Vac control circuit energizes the undervoltage release accessory within the main input circuit breaker when the Emergency Mains Off

(EMO) circuit is closed. An external connection for the EMO circuit is provided by means of a circular plastic connector (CPC) located on the lower right back panel above the convenience receptacles. The power conditioner is shipped with a shorting plug secured to the panel mounted

CPC. The shorting plug has a wire jumper across pins 3 and 4 of the CPC. A spare mating CPC is provided with the unit in the spares compartment to allow for this shorting plug to be replaced with any series connected NC contact string. (See “Emergency Mains Off” on page 26 for detailed description of operation.)

5. In order to turn ON the main input circuit breaker, the EMO circuit must be closed so that the undervoltage release accessory is energized.

ONEAC CDR45I Series Power Conditioner, Installation Guide, 913-521 Rev. A

Installation Principle of Operation

6. Pins 1 and 2 of the CPC provide the user with a pair of contacts that are opened when the EMO circuit has been alarmed and are closed during normal unit operation. (See “Emergency Mains Off” on page 26 for detailed description of operation.)

7. The secondaries of the Mains transformer are connected to the Virtual

Kelvin Ground

8. When the main input circuit breaker is turned ON, power is applied to the cooling fans, and the main output circuit breaker. When the main output circuit breaker in turned ON, the Output Power ON LED is illuminated and power is available at the output power block.

N O T E Proper input voltage configuration is achieved by performing the following three independent steps:

• Selection of the correct rating plug for the desired input voltage.

• Selection of the correct tap configuration for the Mains transformer (T1).

• Selection of the correct tap configuration for the Control transformer (T2).

The power conditioner is originally shipped from the manufacturer configured for 400 Vac input operation unless otherwise stated on the label attached to the input power block.

Emergency Mains Off

This feature will allow you to shut down your power conditioner by pushing the red, mushroom-type EMERGENCY MAINS OFF (EMO) turn-to-release button located on the front upper right corner.

After the EMO circuit has been deployed, the input circuit breaker will need to be reset (switched to the OFF position, then the ON position) to resume normal operation.

Hazardous voltages will still be present within the power conditioner even after the EMO has been deployed.

You must turn off the power source supplying the power conditioner at the service disconnect to remove all hazardous voltages before servicing or working within the power conditioner. In order to comply with SEMI-S2-

93A; 11.2, which complies with 29 CFR 1910.147 (OSHA), the power feed to the power conditioner must be locked out and tagged out at the service disconnect that feeds the power conditioner input power block to deenergize the power conditioner.

The EMO circuitry is integrated with the input circuit breaker with a 24 Vac undervoltage release circuit and controlled by a 24 Vac transformer, which is located in the control transformer area. The transformer is powered prior to the input circuit breaker and is protected by two fuses (2 A, 600 V) on the primary side located below the transformer and behind the middle front panel. The secondary side of the transformer is fuse protected (1 A, 250 V) to limit the current to 1 A maximum. This fuse is also located in the same compartment. A schematic of the 24 Vac control circuit is found at the end of this section.

The conditioner 24Vac EMO circuit is forms a closed loop for normal operation. The loop includes: the red EMO button (contacts open when button depressed), a microswitch S2 behind lower front access panel (contacts closed when switch is depressed by panel), and remote EMO contacts J1-3 and J1-J4

(a closed loop is required between these pins). When the EMO loop is closed,

24Vac is provided to the undervoltage coil of the input circuit breaker permitting it to be set to ON Opening the loop by depressing the red button or other interruption will cause the input circuit breaker to OPEN and remove power from the conditioner load. Releasing the red EMO button (turn to release) will restore 24 Vac to the undervoltage coil and permit the input circuit breaker to be re-set to OFF then to ON.

ONEAC CDR45I Series Power Conditioner, Installation Guide, 913-521 Rev. A

Emergency Mains Off Installation

A circular plastic connector (CPC) is provided on the back of the power conditioner, located above the convenience receptacles, to allow for an external connection to the EMO circuit. A series connected, normally closed string of contacts or switches must be connected between J1-3 and J1-4 of the CPC. The conditioner will not function unless a closed loop exists between these two pins. The power conditioner is shipped with a shorting plug (P1) connected to the panel to allow for field installation and verification. An additional plug with

4 loose pins is shipped with the conditioner. They are stored in the spares compartment above the control transformer.

Pins P1-1 and P1-2 are not used in the shorting plug provided. A pair of contacts, K1A is connected to J1-1 and J1-2 for future user specific circuits.

The contact pair is rated at 250 Vac, 1 A. The relay coil, K1, is energized when power is available to the input circuit breaker undervoltage coil for normal operation. The contact pair K1A is closed when relay K1 is energized.

Alarming the EMO circuit removes power from K1 at the same time as the input circuit breaker undervoltage coil is de-energized. The contact pair K1A will open. Restoring 24 Vac power to normal will close the contact pair K1A.

Note that K1A will be closed whenever the EMO 24V ac power loop is normal even if the input circuit breaker has not been turned ON.
