INSTALLATION ELECTRICAL Step Four Step Five OMEGA's LVP-51 series level switch may be installed anywhere on Supply Voltage: a tank wall using the supplied PE fitting that the switch slides into. The supply voltage to the LVP-51 series level switch should never The fitting comes with adhesive on the tank side that is sufficient to exceed a maximum of 36 VDC. Omega controllers have a built-in 13.5 hold the sensor in position temporarily while the installation is tested, VDC power supply which pro
