Operator is responsible to maintain safe operating conditions. To ensure safe

operating conditions, cards should not be operated beyond the full temperature range

specified in the datasheet. Exceeding safe operating conditions can result in shorter

lifespans, improper card performance and user safety issues. When the cards are in

use and operation within the specified full temperature range is not maintained, card

surface temperatures may exceed safe handling conditions which can cause

discomfort or burns if touched. In the event of a card exceeding the full temperature

range, always allow the card to cool before touching or removing cards from host

computer or chassis.

Acqiris products are designed for use with electrical signals that are rated

Measurement Category I and Measurement Category II, as described in the

International Electrotechnical Commission (IEC) Standard IEC 60664. Most

measurement, control, and data I/O signals are Measurement Category I and must not

be directly connected to mains voltage or to voltage sources with high transient over-

voltages. Measurement Category II connections require protection for high transient

over-voltages often associated with local AC mains connections. Assume all

measurement, control, and data I/O connections are for connection to Category I

sources unless otherwise marked or described in the user documentation.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on

cable connector jacks or test fixtures. The American National Standards Institute (ANSI)

states that a shock hazard exists when voltage levels greater than 30 V RMS, 42.4 V peak, or

60 V DC are present. A good safety practice is to expect that hazardous voltage is present in

any unknown circuit before measuring.

Operators of this product must be protected from electric shock at all times. The responsible

body must ensure that operators are prevented access and/or insulated from every connection

point. In some cases, connections must be exposed to potential human contact. Product

operators in these circumstances must be trained to protect themselves from the risk of

electric shock. If the circuit is capable of operating at or above 1000 V, no conductive part of

the circuit may be exposed.

Do not connect switching cards directly to unlimited power circuits. They are intended to be

used with impedance-limited sources. NEVER connect switching cards directly to AC mains.

When connecting sources to switching cards, install protective devices to limit fault current

and voltage to the card.

Before operating an instrument, ensure that the line cord is connected to a properly-grounded

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.

For maximum safety, do not touch the product, test cables, or any other instruments while

power is applied to the circuit under test. ALWAYS remove power from the entire test system

and discharge any capacitors before: connecting or disconnecting cables or jumpers, installing
