Please note: Power knob on fireman switch FMS200 may be out of order

We have discovered a production error on the FMS200 fireman switch. In connection with high production from the PV-system, the circuit breaker can break, which leads to the entire Ferroamp system shutting down.

We are now working to locate all these products in order to be able to carry out inspections and fix any faults. It is important to note that even if the emergency stop connected to the fireman switch is still working, the power knob located on the fireman switch itself may be out of order. If the knob is turned to "off", the system will remain energized.

Note:

- If the knob is broken, it is indicated by the green light next to the knob continuing to light up even when the knob is "off".

- Always cut off the AC power when working with the DC grid. The DC voltage in the Ferroamp system is automatically cut when the AC power is cut but it does not happen immediately. Always go through a measurement to ensure that the DC network is de-energized before you start working on it.

- The external emergency-stop button still works to break the DC voltage even if the knob on the firefighter switch does not work.
