Inspecting the Unit

When you receive your power system, inspect it for any obvious damage that may have occurred during shipment. If there is damage, notify the shipping carrier and nearest Agilent Sales and Support Office immediately. Refer to www.agilent.com/find/assist.

Until you have checked out the power system, save the shipping carton and packing materials in case the unit has to be returned.

Installing the Unit

Safety Considerations

This power system is a Safety Class 1 instrument, which means it has a protective earth terminal. That terminal must be connected to earth ground through a power source equipped with a ground receptacle.

Refer to the Safety Summary page at the beginning of this guide for general safety information. Before installation or operation, check the power system and review this guide for safety warnings and instructions. Safety warnings for specific procedures are located at appropriate places throughout this Guide.

Environment

WARNING Do not operate the instrument in the presence of flammable gasses or fumes

The environmental conditions of the instrument are documented in Appendix A. Basically, the instrument should only be operated indoors in a controlled environment.

The dimensions of your instrument as well as an outline diagram are given in Appendix A. A fan cools the power system by drawing air through the sides and exhausting it out the side and back. The instrument must be installed in a location that allows sufficient space at the sides and back of the unit for adequate air circulation.

Rack Installation

		You cannot use support rails for rack mounting your instrument.
	CAUTION
		Support rails would block the airflow needed for cooling.
		Use Rack Mount kit (Option 908) to rack mount your instrument.
		The Rack Mount Kit is also available by ordering part number N6709A.

		Agilent N6700 MPS mainframes can be mounted in a 19-inch EIA
		rack cabinet. They are designed to fit in one rack-unit (1U) of space.
		Do not block the air intake and exhaust at the sides of the unit, or the
		exhaust at the rear of the unit.
