SECTION II

INSTALLATION

2-1. INSPECTION. 2-9. THREE-CONDUCTOR POWER CABLE.

	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.
	2-3.	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) re- commends 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 appropri- ate receptacle.

2-11. To preserve the protection feature when oper- ating

three green

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.
