User Warnings and Cautions

The installation and service instructions in this manual are for use by qualified personnel only. Refer to qualified personnel for service.

  • This equipment is not suitable for use in locations where children are likely to be present.

  • To avoid electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so.

  • This instrument has an auto-ranging line voltage input. Ensure the power voltage is within the specified range of 100-240VAC.

  • When servicing equipment with dual power supplies, power must be removed from both supplies before servicing.

  • For equipment that uses PoE (Power over Ethernet), remove the corresponding Ethernet cable before servicing.

  • The "~" symbol, if used, indicates an alternating current supply.

  • Equipment must be connected to protective earthing by means of a power cord connected to a socket outlet.

  • Equipment with an earthing terminal should be connected to a proper ground system with 20 - 14 AWG (0.5 - 1.5mm) wire.

  • Equipment without a dedicated on/off power switch uses the power cord as the primary disconnect mechanism, and the mains power source should be nearby the equipment and easily accessible.

Important Safety Symbols

This symbol, whenever it appears, alerts you to the presence of uninsulated, dangerous voltage inside the enclosure - voltage that may be sufficient to constitute a risk of shock. Disconnect equipment from all power sources before any servicing of parts.

This symbol, whenever it appears, alerts you to important operating and maintenance instructions. Read the manual.

This symbol, whenever it appears, identifies the associated terminal as a protective earth ground for protection against electric shock in case of a fault. The terminal should be connected to a proper ground system with 20 - 14 AWG (0.5 - 1.5mm) wire.

This symbol, whenever it appears, indicates a fuse to protect against excessive current. When replacing fuses, use only the type and rating of the original fuse as indicated by the manufacturer. Never install a fuse with a higher current value.

Hazardous Voltages and Fuses

The instrument power supply incorporates an internal fuse. Hazardous voltages may still be present on some of the primary parts even when the fuse has blown. If fuse replacement is required, replace the fuse only with the same type and value for continued protection against fire.

Electrical Warnings

The product's power cord is the primary disconnect device. The socket outlet should be located near the device and easily accessible. The unit should not be located such that access to the power cord is impaired. If the unit is incorporated into an equipment rack, an easily accessible safety disconnect should be included in the rack design.

For equipment that uses PoE (Power over Ethernet), the corresponding Ethernet cable should also be treated as a disconnect device when connected to a switch that provides PoE.

To reduce the risk of electrical shock, do not expose this product to rain or moisture. This unit is for indoor use only.

This equipment requires the free flow of air for adequate cooling. Do not block the ventilation openings on the rear and sides of the unit. Failure to allow proper ventilation could damage the unit or create a fire hazard. Do not place the units on a carpet, bedding, or other materials that could interfere with any panel ventilation openings.

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

USA Class A Computing Device User Information

This equipment generates, uses, and can radiate radio-frequency energy. If it is not installed and used as directed by this manual, it may cause interference to radio communication. This equipment complies with the limits for a Class A computing device as specified by FCC rules, part 15, subpart j, which are designed to provide reasonable protection against such interferences when this type of equipment is operated in a commercial environment.
