Engineering Data
De-rating
Fig. 1 De-rating for Vertical and Horizontal Mounting Orientation
> 50°C de-rate power by 2.5% / °C
Note
1. Do not use the Redundancy Module in areas
outside the shaded portion as shown in the
above graph, internal parts may occasionally
deteriorate or be damaged.
2. For the power derating refer above graph
ambient temperature > 50°C, the output
capacity has to be reduced by 2.5% per
degree Celsius increase in temperature. If
the output capacity is not reduced when Amb
> 50°C, some device will run into thermal
stress problem, the ORing diodes will get too
hot.
3. If the Redundancy Module has to be
mounted in any other direction please contact
your service provider.
4. In order for the device to function in the
manner intended, it is also necessary to
observe lateral spacing of 20mm. to other
modules.
5. Depending on the ambient temperature and
load of the device, the temperature of the
housing can become very high!
6. If the device has to be mounted in any other
orientation, please do not hesitate to contact
[e-mail] for more details.
Assembly & Installation
The power supply unit (PSU) can be mounted on 35mm DIN rails in accordance with EN 60715. The device should be installed with
input terminal block at the bottom.
Each device is delivered ready to install.
Mounting
Dismounting
.
Fig. 2.1 Mounting
Snap on the DIN rail as shown in Fig. 2.1:
1. Tilt the unit upwards and insert it onto the DIN rail.
2. Push downwards until stopped.
3. Press against the bottom front side for locking.
4. Shake the unit slightly to ensure that it is secured.
Fig. 2.2 Dismounting
To uninstall, pull or slide down the latch with screw driver as
shown in Fig. 2.2. Then slide the power supply unit (PSU) in
the opposite direction, release the latch and pull out the power
supply unit (PSU) from the rail.
