Bender EDS3090/-91/-92/-96 series

Closing of operation: Shut down the equipment and organize the measuring pliers and cables.

Installation and usage precautions

（1） Installation specifications

Cable connection: When connecting the injector to the system, it is necessary to distinguish between the phase sequence and the PE end, and the green and yellow grounding wires must be reliably grounded; When measuring the clamp connection, the BNC joint should be tightened to avoid poor contact;

Voltage Expansion: When the system voltage exceeds AC 575V/DC 504V, AGE185 coupler must be connected in series, otherwise it may damage the equipment;

Measurement clamp matching: The main circuit must use PSA30 series clamps, and the control circuit must use PSA33 series clamps, which cannot be mixed, otherwise the measurement accuracy cannot be guaranteed;

Environmental requirements: Avoid use near corrosive gases, strong vibrations, direct sunlight, or heat sources. Protect against humid environments and ensure ventilation and heat dissipation of equipment.

（2） Safety operation taboos

Live operation: Strictly comply with the safety level requirements of CAT III/CAT IV, and operators must wear protective equipment such as insulated gloves and insulated shoes;

Power supply safety: Use the original matching power adapter or batteries that meet the specifications, and prohibit the use of non-standard 5V USB power supplies to avoid overvoltage damage;

Equipment modification: It is not allowed to disassemble, modify equipment or replace non original parts without authorization, otherwise the warranty will be invalid and there will be safety risks;

Troubleshooting: When the equipment malfunctions, immediately stop using it and contact Bender's official after-sales service for repair. Do not disassemble or repair it yourself;

Battery maintenance: When not in use for a long time, the battery should be removed to avoid leaking and damaging the equipment; When charging, use the original USB charger, and the charging time should not exceed 5 hours.

（3） Maintenance and Calibration

Daily maintenance: Regularly clean the equipment casing and measuring pliers with a dry cloth to avoid dust and oil accumulation; Check whether the insulation layer of the cable is damaged and whether the BNC joint is oxidized;

Calibration requirements: The equipment needs to be regularly returned to Bender's original factory or authorized institution for calibration to ensure measurement accuracy meets standards. The recommended calibration cycle is 1-2 years;

Accessory replacement: When vulnerable parts such as measuring pliers and cables are damaged, original accessories need to be replaced. After replacement, a simple test should be conducted to confirm that the equipment is working properly.
