3. INSTALLATION

3.1.

PACKING

Unpack the unit, being careful to retain all packing

materials until the unit has been checked for possible

concealed damage. The power cord is packed with the

unit and attaches to a 3-pin connector that is mounted on

the rear of the 4002A.

3.2.

SELECTING THE MAINS VOLTAGE

The 4002A is designed so that the transformer primary can

be connected in a configuration that is compatible with

the availabie mains voltage. Check the voltage level to be

used and select the appropriate range on the 4002A. A

small printed circuit card is installed in a recessed portion

of the power connector that is covered by a clear plastic

window. The orientation of the small printed circuit card

determines the nominal voltage and the result is visible

through the plastic window. The four alternate settings

are 100, 120, 220, and 240 V, and each selects an input

range as defined in Section 2, "INPUT." If the setting does

not match the available ac voltage level, use the following

steps to change it;

1. Remove the ac power cord.

2. Slide the clear plastic window from its operating

position (over the fuse) to its alternate position over the

ac power plug connector.

3. Remove the fuse by pulling outward on the handle

marked "Fuse Pull."

Extract the small printed circuit card.

5. Orient the printed circuit so that the desired voltage

is readable; the selections are 100, 120, 220, and 240.

Insert the small printed circuit back into the slot

under the fuse location and check to see if desired voltage

is visible.

7. Return the handle (marked "Fuse Pull") to its original

position.

8. Install the fuse with the proper rating; use a 3 A fuse

for 100 or 120 V; use a 1.5 A fuse for 220 or 240 V.

9. Slide the plastic window back to its position covering

the fuse.

10. Leave the power cord disconnected while mounting

or dismounting the 4002A.

The 4002A power supply is normally supplied factory con

nected to an EG&G GRIEG 4001G Modular System Bin.

However, the supply is designed to TID-20893 (Rev) speci

fications and may be attached, in the space provided, to

any bin manufactured to those specifications.

For attachment to a bin other than an EG&G GRIEG 401

or 4001 Series Bin, please refer to the appropriate instruc

tion manual. The Gn-Gff switch and othercontrols neces

sary to operate the supply are part of the bin and not

furnished with the power supply.

For attachment to the 4001G bin the following steps are

advised;

IMPORTANT NOTICE

Always disconnect the power cord at the power supply

chassis before connecting or disconnecting the bin-

power suppiy connector (PG13-PG14). Faiiure to do so

wiil result in a shock hazard at PG14 and can also damage

the power supply and/or bin contents.

1. Place the bin on a table with the back part facing you.

Place the power supply in the proper mounting position,

leaving enough space between the two pieces to attach

the interface connector.

2. After ensuring that the power cord is disconnected,

mate the interface connector, being careful to align the

polarizing pins. Fold and form all wiring close to the con

nector edges to prevent any wires from being pinched and

producing a short circuit in succeeding steps.

3. Mount the power supply to the bin by securely tight

ening the four 10-32 screws, being careful not to pinch any

wires or to use undue force on any parts.

When attaching the 40G2A power supply to very old 401

bins it is necessary to first remove the left and right side

covers and stand the bin on its front face (handles down).

From this point on, assembly is the same; upon com

pletion the side plates should be replaced.
