PIRD20.241

PIANO-Series

This redundancy module is designed for installation in an enclosure and is intended for the general use such as in

industrial control, office, communication, and instrumentation equipment.

This redundancy module can be used with any type of power supply as long as the maximum output current ratings

are not exceeded. It is suitable for power supplies with constant current overload behavior as well as any kind of

“Hiccup” overload behavior.

Do not use this redundancy module in equipment, where malfunction may cause severe personal injury or threaten

human life.

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

This device does not contain serviceable parts.

If damage or malfunction should 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 top and the output terminals on the

bottom of the unit.

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

not cover the ventilation grid (e.g. cable conduits) by more than 30%!

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 output current. Increase the side clearance to 15mm in case the adjacent device is a heat source (e.g. another

power supply).

The input must be powered from a SELV source (according to IEC 60950-1), a PELV source (according to IEC 62477-1) or

an Isolated Secondary Circuit (according to UL 508).

WARNING

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

- 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 open, modify or repair the unit.

- 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.
