Installation 2

Bench Installation

Do not block the air intake and exhaust at the sides, or the exhaust at the rear of the unit. Refer to the outline diagram in Appendix A. Minimum clearances for bench operation are 2 inches (51 mm) along the sides and back.

Channel Number

	The channel number of a power module is determined by the location
	of that module in the mainframe. When viewed from the rear, the
	module next to the GPIB connector is always output channel one.
	Numbering continues sequentially to the left, from one to four.
	If there are less than four modules, channel numbering corresponds
	to the actual number of installed power modules. Unused channel
	slots must contain filler modules to ensure proper airflow for cooling.
	Double-wide power modules are assigned the channel number of the
	lowest numbered slot in which is installed. For example, if a double-
	wide module is installed in slots 3 and 4, it is assigned channel
	number 3.
	Power modules that are connected in parallel and have been configured or
NOTE
	grouped to act as a single, higher-power channel are addressed using the
	channel number of the lowest channel in the group.

400 Hz Operation

Redundant Ground Requirement

At 400 Hz AC input operation, the leakage current of the unit exceeds

3.5mA. This requires the installation of a permanent, redundant ground from the instrument chassis to earth ground. This ensures that ground will always be connected and that any leakage current will be diverted to ground. Refer to the Service Guide for installation instructions.

Power Factor

At 400 Hz AC input operation, the unit’s power factor is affected as follows:

Under full load at 400 Hz, power factor drops from 0.99 (@120

VAC) to as low as 0.76 (@ 265 VAC).

Power factor degrades further under no load conditions.

Cleaning

WARNING SHOCK HAZARD To prevent electric shock, unplug the unit before cleaning.

Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally.
