This device is designed for installation in an enclosure and is intended for the general professional use such as in

industrial control, office, communication, and instrumentation equipment.

Do not use this power supply in equipment, where malfunction may cause severe personal injury or threaten human

life.

WARNING

Risk of electrical shock, fire, personal injury or death.

- Do not use the power supply without proper grounding (Protective Earth). Use the terminal on the input block for

earth connection and not one of the screws on the housing.

- Turn power off before working on the device. Protect against inadvertent re-powering.

- Make sure that the wiring is correct by following all local and national codes.

- Do not modify or repair the unit.

- Do not open the unit as high voltages are present inside.

- Use caution to prevent any foreign objects from entering the housing.

- Do not use in wet locations or in areas where moisture or condensation can be expected.

- Do not touch during power-on, and immediately after power-off. Hot surfaces may cause burns.

Obey the following installation requirements:

- This device may only be installed and put into operation by qualified personnel.

- Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.

- The device is designed for use in pollution degree 2 areas in controlled environments.

- The enclosure of the device provides a degree of protection of IP20 according to IEC 60529.

- Mount the unit on a DIN-rail so that the input terminals are located on the bottom of the unit. For other mounting

orientations see de-rating requirements in this document.

- The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do

not cover ventilation grid (e.g. cable conduits) by more than 15%!

- Keep the following installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right sides are

recommended when the device is loaded permanently with more than 50% of the rated power. Increase this

clearance to 15mm in case the adjacent device is a heat source (Example: another power supply).

- Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are

designed for a minimum operating temperature of 60°C for ambient temperatures up to +45°C, 75°C for ambient

temperatures up to +60°C and 90°C for ambient temperatures up to +70°C. Ensure that all strands of a stranded wire

enter the terminal connection. Check also local codes and local requirements. In some countries local regulations

might apply.

- This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect. If

damage or malfunction should occur during installation or operation, immediately turn power off and send the

device to the factory for inspection.

- The device is designed, tested and approved for branch circuits up to up to 30A (UL) or 32A (IEC) without additional

protection device. If an external fuse is utilized, do not use circuit breakers smaller than 10A B- or C-Characteristic to

avoid a nuisance tripping of the circuit breaker.

- A disconnecting means shall be provided for the input of the power supply.
