1. Intended Use

• 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.

2. Installation Requirements

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

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

• Should damage or malfunction occur during installation or operation, immediately turn power off and send unit to the factory for inspection.

• Mount the unit on a DIN rail so that the input terminals are located on the bottom of the unit. For other mounting orientations, refer to derating

requirements in this document.

• This 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 30%!

• Keep the following installation clearances: 40mm on top, 20mm on the bottom, 0mm on the left and right sides. Increase this clearance to 15mm in case the adjacent device is a heat source (e.g. another power supply).

SHOCK HAZARD: 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.

WARNING: EXPLOSION HAZARDS!

Substitution of components may impair suitability for this environment. Do not disconnect the unit or operate the voltage adjustment or S/P jumper unless power has been switched off or the area is known to be non-hazardous.

All parameters are specified at 24V, 2.5A, 230Vac input, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.

Peak current capability (up to several milliseconds)

The power supply can deliver a peak current which is higher than the specied short term current. This helps to start current demanding loads or to safely operate subsequent circuit breakers.

The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will be discharged and causes a voltage dip on the output. Detailed curves can be found in section 21.1.
