# SMART BILGE + 24Vac Voltage selector link

## Details on how to install the voltage selector link within your SmartBilge+ (For use with 24Vac monitors).

### Detail

The SMART BILGE+ has three available power supply options, which are dictated by the power supply you have available on your analyser. 

If you have a 24Vac power supply, you must ensure that the SMART BILGE + has a 24Vac solenoid valve fitted and also that the blue 24V voltage selector link is fitted to the control PCB as shown below. 

The voltage selector link must not be fitted to any 115V or 230V SMART BILGE + monitors to avoid permanent damage to the controller PCB. 

You must ensure that all power to the system is isolated prior to removing the cover of the SMART BILGE + control module.
