CONC.CFO 521 / FO SENSORS
The CFO 521 concentrator must be mounted on one side of the transformer, as shown in the image below:
During installation, the following indications must always be observed:
Do not place the concentrator near the hot air flow from the windings or from the core. The operating temperature of the
concentrator ranges from -25°C to 60°C, therefore ensure there is adequate space between the concentrator and the
transformer. Maximum humidity 90% (non-condensing).
The CFO 521 support bracket could facilitate this operation. Always respect the safety distance, suggested by the
transformer manufacturer, from the transformer windings. Fix the bracket, on one of the sides of the transformer, using the
8mm hole with an M8 pin with nut and washer.
