Supply connection and grounding requirements
Before operating an instrument, make sure that the line cord is connected to a properly grounded, appropriately
rated power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or
breaks before each use.
When installing equipment where access to the main power cord is restricted, such as rack mounting, a
separate main input power disconnect device must be provided in close proximity to the equipment and within
easy reach of the operator.
Assembly, location, and mounting requirements
The 2601B-PULSE can be mounted in a standard 19-inch rack (horizontal mountings only; mounting vertically
may impede the cooling mechanisms).
When rack mounting the 2601B-PULSE, make sure there is adequate airflow around at least one side to
ensure proper cooling. Adequate airflow enables air temperatures within approximately one inch of the
2601B-PULSE surfaces to remain within specified limits under all operating conditions. The cooling
specifications state:
▪ Forced air
▪ Side intake, rear exhaust
▪ One side must be unobstructed when rack mounted
Ventilation requirements
To prevent damaging heat build-up and ensure specified performance, observe the following precautions.
The rear exhaust vent and at least one side vent must be kept free of any obstructions. Even partial blockage
could impair proper cooling.
▪ Do not position any devices adjacent to the 2601B-PULSE that force air (heated or unheated) into or onto
its cooling vents or surfaces. This additional airflow could compromise accuracy performance.
▪ When rack mounting the 2601B-PULSE, make sure there is adequate airflow around at least one side to
ensure proper cooling. Adequate airflow enables air temperatures within approximately one inch of the
2601B-PULSE surfaces to remain within specified limits under all operating conditions.
▪ Do not rack-mount high power-dissipation equipment adjacent to the 2601B-PULSE that could cause
excessive heating to occur. The specified ambient temperature must be maintained around the surfaces of
the 2601B-PULSE to maintain specified accuracies.
