2-2.‘This instrument was carefully inspected both

 

mechanically and electrically, before shipment. It

 

should be physically free of mars or scratches and in

 

perfect electrical order upon receipt. To confirm

 

this, the instrument should be inspected for physical

 

damage in transit. Also, check for supplied acces-

.

sories, and test

the electrical performance of the in-

strument using

the procedure outlined in Paragraph

 

5-5Performance Checks. If there is any

 

damage or deficiency, refer to

 

paragraph

1-A.3.

INSTALLATION.

 

 

2-4. The

Model 410C is transistorized except for

 

one vacuum tube and requires no special cooling.

 

However, the instrument should not be operated where

 

the ambient temperature exceeds 55° C (140° F).

 

2-5. RACK MOUNTING.

 

 

2-6. The Model 410C is a submodular unit designed

 

for bench use. However, when used in combination

 

with other submodular units, it can be bench and/or

 

rack mounted.

The Combining Cases and Adapter

 

Frame are designed specifically for this purpose.

 

2-7. MODELS 1051A AND 1052A COMBINING CASES.

 

The Combining Cases are full-module unita which

 

accept various

combinations of submodular units.

 

Beinga full width unit, it can either be bench or rack

 

mounted. An illustration of the Combining Case is

 

shown in Figure 2-1.Instructions for installing the

 

Model 410C are shown in Figure 2-2.

 

 

2-8. RACK ADAPTER FRAME (

Part No. 5060-

 

0797). The adapter frame is a rack mounting frame

 

that accepts various combinations of submodular

 

units. It can be rack mounted only.

An illustration

 

of the adapter frame is given in Figure 2-3. Instruc-

 

tions are given below.

 

 

 

a. Place the adapter frame on edge of bench as

 

shown in step 1, Figure 2-4.

 

 

 

b. Stack the submodular units in the frame as

 

shown instep 2, Figure 2-4.Place the spacer clamps

 

between instruments as shown in step 3, Figure 2-4.

 

 

c. Place spacer clamps on the two end instruments

 

(see step 4, Figure 2-4) and push the combination into

 

the

frame.

 

 

 

d. Insert screws on either side of frame, and tighten until submodular instruments are tight in the frame.

e.The compiete assembly is ready for rack mounting.

2-10.To protect operating personnel, the National Electrical Manufacturers’ Association (NEMA) recommends that the instrument panel and cabinet be

grounded. All Hewlett-Packard instruments

are

equipped with a three-conductor power cable

which

grounds the instrument when plugged into an appropriate receptacle.

2-12. PRIMARY POWER REQUIREMENTS.

2-13.The Modei 410C can be operated from either 115 or 230 volts, 50 to 1000 cps. The instrument can be easily converted from i 15- to 230- volt operation. The LINE VOLTAGE switch, S4 a two-positionslide

switch located at the rear of the instrument, selects the mode of AC operation. The line voltage from which the instrument is set to operate appears on the siider of the switch. A 0.25-ampere,slo-blo fuse is

used for both 115- and 230-volt operation.
