Safety Instructions

Please read these safety instructions carefully and retain them for future reference.

General Safety Guidelines

1. Keep the chassis area clean and dust-free before, during, and after installation.

2. Do not wear loose clothing or jewelry when working around the chassis. Secure ties, scarves, and roll up sleeves.

3. Wear safety glasses when working in conditions that may pose a risk to your eyes.

4. Always disconnect power before installing or removing a chassis or working near power supplies. Turn off the power and unplug the power cord.

5. Do not work alone in potentially hazardous conditions.

6. Never assume that power is off—always check the circuit before beginning work.

Lithium Battery Caution

1. ⚠️ Risk of Explosion: Use only the recommended battery type. Dispose of used batteries according to local regulations.

2. Installation should only be performed by qualified personnel familiar with relevant device specifications.

3. Do not lift or carry the power supply by its handle.

4. Do not dispose of batteries in fire or expose them to high temperatures or mechanical damage.

5. Batteries exposed to extreme heat or low air pressure may explode or leak flammable gases or liquids.

Operating Safety

1. Ensure the operating environment has adequate air circulation. Electrical equipment generates heat and requires proper ventilation.

2. Always secure the chassis cover to maintain proper airflow.

3. Protect sensitive components from electrostatic discharge (ESD).

4. Use an ESD wrist strap that makes direct contact with your skin. If unavailable, ground yourself by touching the metal part of the chassis.

5. Check the resistance of your antistatic strap periodically—it should be between 1 and 10 megohms (MΩ).

Mounting and Installation Precautions

1. Do not install or operate the equipment near flammable materials.

2. In rack-mounted setups, ensure ambient temperature does not exceed the unit’s maximum rated temperature.

3. Maintain unobstructed intake and exhaust ventilation to ensure safe airflow.

4. Ensure even mechanical loading when mounting to prevent hazardous conditions.

5. Avoid overloading supply circuits; check nameplate ratings for reference.

6. Ensure reliable grounding, especially when using power strips or indirect connections.

Installation & Operation

1. This equipment must be installed by trained specialists only. Improper installation can lead to falls, damage, or injury.

2. Welotec GmbH shall not be liable for damages due to insufficient mounting strength or inappropriate components.
