1.2. Safety Notice

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. Neither Magna-Power Electronics nor any of the associated sales organizations accept responsibility for personal injury, consequential injury, loss, or damage resulting from improper use of the equipment and accessories.

Installation and service must be performed only by properly trained and qualified personnel who are aware of dealing with electrical hazards. Ensure that the AC power line ground is properly connected to the MagnaLOAD electronic load chassis. Furthermore, other power grounds, including those connected to application maintenance equipment, must be grounded for both personnel and equipment safety.

This product is a Safety Class 1 instrument, provided with a protective earth terminal. The protective features of this product may be impaired if it is used in a manner not specified in the operation instructions.

Warning

Residual voltage. Lethal voltages may be present inside the MagnaLOAD electronic load even when the AC input voltage is disconnected. Only properly trained and qualified personnel should remove covers and access the inside of the MagnaLOAD electronic load.

During normal operation, the operator does not have access to hazardous voltages within the product’s chassis. Depending on the application, high voltages hazardous to human safety may be present on the DC power terminals. Ensure that the DC power cables are properly labeled as to the safety hazards and that any inadvertent contact with hazardous voltages is eliminated.

Do not install substitute parts or perform unauthorized maintenance on the product.

These operating instructions form an integral part of the equipment and must be available to the operating personnel at all times. All the safety instructions and advice notes are to be followed.

Warning

General. Do not use this product in any manner not specified by the manufacturer. The protective features of this product may be impaired if it is used in a manner not specified in the operating instructions.

Warning

Environmental Conditions. Never use the instrument outside of the specified environmental conditions described in the Environmental Characteristics of the specifications.

Warning

Ground the Instrument. This product is provided with protective earth terminals. To minimize shock hazard, the instrument must be connected to the AC mains through a grounded power cable, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in injury or death.

Warning

Before Applying Power. Verify that all safety precautions are taken. All connections must be made with the unit turned off, and must be performed by qualified personnel who are aware of the hazards involved. Improper actions can cause fatal injury as well as equipment damage. Note the instrument’s external markings described under “Safety Symbols”.

Warning

Do Not Operate in an Explosive Atmosphere. Do not operate the instrument in the presence of flammable gases or fumes.

Warning

Do Not Remove the Instrument Cover. Only qualified, service-trained personnel who are aware of the hazards involved should remove instrument covers. Disconnect the power cable and any external circuits before removing instrument covers.
