RHINO PSH-xx-480 Power Supplies

Installation Instructions

READ INSTRUCTIONS BEFORE INSTALLING OR OPERATING
THIS DEVICE. KEEP FOR FUTURE REFERENCE.

Safety Instructions and Warnings

• Do not open the device!

• Before any installation or maintenance, ensure that the main
switch is switched off and prevented from being switched on
again.

• The device must be installed and put into service by qualified
personnel only.

• Never work on the device if power is applied.

• Risk of electric arcs and electrical shock, which can cause death,
severe personal injury or substantial property damage.

• The unit must be connected to the mains supply in compliance
with national regulations (e.g., VDE0100 and EN50178). All wire
strands must be fastened in the terminal blocks. (Potential danger
of contact with the case.)

• All input and output wires must be properly rated for the power
supply and must be connected with the correct polarity (Fig. 3).

• The Power Supply wiring must be sufficiently fused.

• Sufficient cooling must be ensured (Fig. 2).

• Do not introduce any objects into the device.

• The output voltage adjustment potentiometer may only be
actuated using an insulated screwdriver.

• Keep away from fire and water.

• The internal fuse is not accessible. If this internal fuse has blown,
the power supply has an internal defect and, for safety reasons,
must be replaced.

• This device is designed for use in a clean, dry environment.

• The device must be mounted in an enclosure in the end
application and must not be accessible in operation.

Installation Instructions

• The device can be mounted onto 35mm DIN rails, compliant with
the specifications of DIN EN 50022. Observe the requirements for
ventilation space above and below the device (Fig. 2).

• The standard mounting orientation is with input terminals at the
bottom.

• Alternative side-mounting for flat panels: The case offers the
potentially useful feature to fix the DIN-rail clip to the side wall to
mount inside flat panels.

Recycling

• The device contains elements that are suitable for recycling,
and components that need special disposal. You are therefore
requested to make sure that the device will be recycled at the
end of its service life.

Notes for Technical Specifications Table:

1. Output voltage can be adjusted as indicated. However, output power has to be maintained at nominal value. This

means the output nominal current has to be reduced in accordance with the increase of output voltage.

2. In case of an internal error, a second voltage regulation loop keeps the output voltage at a safe level, and the power

supply turns off and restarts after 10 seconds.

3. When external voltage is supplied above set output voltage and below OVP threshold, the power supply will function

normally without switch off or destruction, even if external voltage is applied continuously.

4. In case of overload or short circuit, the unit switches the output voltage off after 4 seconds and tries to restart every

10 seconds.
