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!
