INSTRUCTION MANUAL CORRECTION

THE POWER SUPPLIER™

Please note the following corrections to the standard Instruction Manual for ATE models plus all the other manuals for specials or “-MG” models derived from it as indicated:

A) PAR. 3.8 PARALLEL OPERATION OF ATE (-MG MODELS) POWER SUPPLIES

Add the following note:

NOTE THE FOLLOWING

CAUTION: When connecting units in parallel, use an external master ON/OFF circuit breaker or switch to simultaneously turn on/off all units connected in parallel. The individual circuit breakers should be left in the ON position working as an overcurrent and overvoltage protection circuit and should not be used as a power ON/OFF switch.

If the above recommendations are not met, the internal turn-off overshoot eliminator circuit could be damaged to the point where it is no longer operational.

B) SECTION III, FIGURES 3-4, 3-5, 3-6, 3-8, 3-10, 3-14, 3-15, 3-16, 3-20, 3-22, 3-25,

3-26, 3-28, 3-30

These diagrams show the load connected using remote sensing. For local sensing leave the links between TB201 terminals 2 (-) S and 3 (-) M and between terminals 5 (+) M and 6 (+) S in place. Disconnect the remote sensing wires from TB 201 terminals 2 (-) S and 6 (+) S to the load.

C) PAR. 3-37 through 3-90 REDUCING RISE TIME DELAY WHEN USING EXTERNAL

PROGRAMMING, EITHER FAST OR SLOW MODE

To reduce the rise time delay, make sure that for the "low" level of the programming signal the output voltage has a small value, at least 0.1% of nominal (with the correct polarity).

D) PAR. 3-115. PROGRAMMING WITH REFERENCE TO THE NEGATIVE POWER SUPPLY

OUTPUT

When the ATE power supply is used in FAST MODE, with a programming reference to the negative output of the unit (see PAR. 3-115 and Figure 3-29) some oscillation may be present at the output. This can be avoided by installing a ceramic capacitor between PC12, pins 1 and 2. The capacitor value is model

dependent, within the range 1.2nF to 4.7nF, and it must be rated for more than the nominal output voltage of the unit.

NOTES:

1. When the ceramic capacitor is installed at PC 12, pins 1 and 2, the 3-dB frequency bandwidth of the unit in FAST MODE is reduced by a factor of from 1.5 to 2.5. Correspondingly, the response time will be increased by the same factor.

2. To reduce the rise time delay, see C) above: REDUCING RISE TIME DELAY ....

3. To reduce the fall time delay, adjust the current limit to a higher value than maximum application current to ensure that for the "high" level of the programming signal the unit is not forced to enter current limit mode.

4. To prevent the unit from going into over-voltage protection and shutting down when the low impedance programming source is disconnected, install a 10 Kohm resistor (1%, 0.125W) at the input programming terminals of PC 12.

5. To reduce a-c line-related noise at the output, connect one of the following to the ATE chassis GND terminal.: 1) the return of the programmind source, 2) the corresponding output terminal of the ATE, or 3) the corresponding Load terminal. In addition, make sure that all devices are tied to the same GND connection; it is recommended that all devices in use by powered by the same a-c outlet.

Conditions of Conformance

When this product is used in applications governed by the requirements of the EEC, the following restrictions and conditions apply:

1. For European applications, requiring compliance to the Low Voltage Directive, 73/23/EEC, this power supply is considered a component product, designed for "built in“ applications. Because it is incomplete in construction, the end product enclosure must provide for compliance to any remaining electrical safety requirements and act as a fire enclosure. (EN61010-1:2001, Cl. 6, Cl. 7, Cl.8, and Cl. 9)

2. This power supply is designed for stationary installation, with mains power applied via a detachable power supply cord or via direct wiring to the source power terminal block.

3. This power supply is considered a Class 1 (earthed) product, and as such depends upon proper connection to protective earth for safety from electric shock. (EN61010-1 Cl. 6.5.4)

4. This power supply is intended for use as part of equipment meant for test, measurement and laboratory use, and is designed to operate from single phase, three wire power systems. This equipment must be installed within a suitably wired equipment rack, utilizing a three wire (grounded) mains connection. See wiring section of this manual for complete electrical wiring instructions. (EN61010-1 Cl.

6.5.4 and Cl.6.10.1)

5. This power supply has secondary output circuits that are considered hazardous, and which exceed

240 VA at a potential of 2V or more.

6. The output wiring terminals of this power supply has not been evaluated for field wiring and, therefore, must be properly configured by the end product manufacturer prior to use.

7. This power supply employs a supplementary circuit protector in the form of a circuit breaker mounted on the front panel. This circuit breaker protects the power supply itself from damage in the event of a fault condition. For complete circuit protection of the end product, as well as the building wiring, it is required that a primary circuit protection device be fitted to the branch circuit wiring. (EN61010-

1:2001, Cl. 9.5)

8. Hazardous voltages are present within this power supply during normal operation. All operator adjustments to the product are made via externally accessible switches, controls and signal lines as specified within the product operating instructions. There are no user or operator serviceable parts within the product enclosure. Refer all servicing to qualified and trained Kepco service technicians.

This product is designed for use in accordance with EN 61010-1 and UL 3101 for Installation Category 2,

Pollution Degree 2. Hazardous voltages are present within this product during normal operation. The product should never be operated with the cover removed unless equivalent protection of the operator from accidental contact with hazardous internal voltages is provided:

!

!

There are no operator serviceable parts or adjustments within the product enclosure.

Refer all servicing to trained service technician.

!

Source power must be removed from the product prior to performing any servicing.

This product is factory-wired for the nominal a-c mains voltage indicated on the rating nameplate located adjacent to the source power connection on the product's rear panel. To reconfigure the product input for other nominal mains voltages as listed herein, the product must be modified by a trained service technician.

2. Grounding

This product is a Class 1 device which utilizes protective earthing to ensure operator safety.

!

The PROTECTIVE EARTHING CONDUCTOR TERMINAL must be properly connected prior to application of source power to the product (see instructions on installation herein) in order to ensure safety from electric shock.

PROTECTIVE EARTHING CONDUCTOR TERMINAL - This symbol indicates the point on the product to which the protective earthing conductor must be attached.

EARTH (GROUND) TERMINAL - This symbol is used to indicate a point which is connected to the PROTECTIVE EARTHING TERMINAL. The component installer/ assembler must ensure that this point is connected to the PROTECTIVE EARTH-

ING TERMINAL.

CHASSIS TERMINAL -This symbol indicates frame (chassis) connection, which is supplied as a point of convenience for performance purposes (see instructions on grounding herein). This is not to be confused with the protective earthing point, and may not be used in place of it.

3. Electric Shock Hazards

This product outputs hazardous voltage and energy levels as a function of normal operation. Operators must be trained in its use and exercise caution as well as common sense during use to prevent accidental shock.

!

This symbol appears adjacent to any external terminals at which hazardous voltage levels as high as 500V d-c may exist in the course of normal or single fault conditions.

This symbol appears adjacent to any external terminals at which hazardous voltage levels in excess of 500V d-c may exist in the course of normal or single fault conditions.
