Safety & Warnings
This product and related documentation must be reviewed for familiarization with safety markings and instructions before operation. It has been designed and tested in accordance with IEC Publication 1010, “Safety Requirements for Electronic Measuring Apparatus,” and has been supplied in a safe condition. The documentation contains information and warnings which must be followed to ensure safe operation and maintain the product in a safe condition.
A safety earth ground must be provided from the main power source to the product input wiring terminals, power cord, or supplied power cord set. Safety symbols indicate potential instrument damage, hazardous voltages, and earth (ground) terminals.
Warnings denote hazards that could result in personal injury if not correctly adhered to. Cautions denote potential damage to the product if not correctly adhered to. The product is a Safety Class I instrument with a protective earthing ground incorporated in the power cord. The mains plug must only be inserted in a socket outlet with a protective earth contact. Any interruption of the protective conductor is prohibited and likely to make the product dangerous.
If the protection is impaired, the instrument must be made inoperative and secured against unintended operation. When using an auto transformer for voltage reduction, ensure the common terminal is connected to the earth terminal of the power source. The product must be used in a normal condition with all means for protection intact. There are no operator serviceable parts; servicing should be referred to qualified personnel. To prevent electrical shock, do not remove covers or perform servicing unless qualified.
Opening covers or removing parts may expose dangerous voltages. Disconnect the product from all voltage sources while it is being opened. The power cord is connected to internal capacitors that may remain live for 5 seconds after disconnecting from the power supply. Replace line fuses only with 250 V fuses of the same current rating and type. Always use the three-prong AC power cord supplied to ensure adequate earth grounding.
The product is designed for use in Installation Category II and Pollution Degree 2 per IEC 1010 and IEC 664, respectively, and is for indoor use only. The product has autoranging line voltage input; ensure the supply voltage is within the specified range. To prevent electrical shock, disconnect the instrument from mains before cleaning. Use a dry cloth or one slightly dampened with water for external cleaning. Do not attempt internal cleaning.
When installing the product in a cabinet, ensure convection into and out of the product is not restricted. The ambient temperature must be less than the maximum operating temperature of the product by 4° C for every 100 watts dissipated in the cabinet. If total power dissipation exceeds 800 watts, forced convection must be used.
