Safety Considerations

This section covers safety considerations relating to the installation and use of the instrument.

Instrument Installation

Install the instrument so that the detachable power cord is readily identifiable and is easily reached by the operator. The detachable power cord is used to completely disconnect the instrument. The front panel switch is only a standby switch which maintains standby power to some parts of the instrument. It does not disconnect the instrument from the power source. Alternatively, an externally installed switch or circuit breaker (which is readily identifiable and is easily reached by the operator) may be used as a disconnecting device.

The input power ranges for the power supply are 90 to 132 V, or 195 to 250 Vrms. The power supply automatically senses the input power and switches between these two ranges. There is no customer replaceable power fuse.

The power cord is connected to internal capacitors that may remain live for 5 seconds after the plug is disconnected from its power supply.

If this product is to be energized via an external autotransformer for voltage reduction, make sure that its common terminal is connected to a neutral (earthed pole) of the power supply.

This instrument has autoranging line voltage input, be sure the supply voltage is within the specified range.

VENTILATION REQUIREMENTS: When installing the product in a cabinet, the convection into and out of the product must not be restricted. The ambient temperature (outside the cabinet) must be less than the maximum operating temperature of the product by 4° C for every 100 watts dissipated in the cabinet. If the total power dissipated in the cabinet is greater than 800 watts, then forced convection must be used.
