Safety & Warnings
The following general safety precautions must be observed during all phases of operation of this instrument. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the instrument. We assume no liability for the Customer’s failure to comply with these requirements.
ENVIRONMENTAL CONDITIONS
This instrument is intended for indoor use, pollution degree 2 environments. It is designed to operate at a maximum relative humidity of 95% and at altitudes of up to 2000 meters. Refer to the specifications tables for the AC mains voltage requirements and ambient operating temperature range.
BEFORE APPLYING POWER
Verify that all safety precautions are taken. Note the instrument’s external markings described under “Safety Symbols”.
GROUND THE INSTRUMENT
This product is a Safety Class 1 instrument (provided with a protective earth terminal). To minimize shock hazard, the instrument chassis and cover must be connected to an electrical ground. The instrument must be connected to the AC mains power through a grounded power cable, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. Note: Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in personal injury.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of fumes or flammable gases.
KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must not remove instrument covers except as instructed in this guide for installing or removing electronic load modules. Component replacement and internal adjustments must be made only by qualified service personnel. Do not replace components with power cable connected. Under certain conditions dangerous voltages may exist even with the power cable removed. To avoid injuries, always disconnect power, discharge circuits, and remove external voltage sources before touching components.
DO NOT SERVICE OR ADJUST ALONE
Do not try to do some internal service or adjustment unless another person capable of rendering first aid resuscitation is present.
