Instrument location
This instrument is intended for indoor use in a pollution degree 2 environment. Please refer to the
specifications table for the allowable environment operating limits.
Significant power may be dissipated in the DC Load, which includes one or more thermostatically-
operated fans. The fans draw air through the bottom and sides and exhaust it out the back. It is
important to allow at least 25 mm (1 inch) of clearance on all sides of the instrument so adequate
cooling airflow can be maintained.
CAUTION
Do not block the fan exhaust at the rear of the load.
