The PR120/V-PR120/LV used for voltages from 100V 1000V, the PR120/ LV used for voltages from 24V 48V. The module comes with "Power" LED and sealable isolator for dielectric stiffness tests.1. The following tables show the voltage values the MEASURING module's input for which the relays and modules are enabled: PR122/DC and PR123/DC Relay PR120/K Module ENABLING Enabling threshold (Voltage) PR122-PR123/DC Relay PR120/K Relay display backlighting PR120/V PR120/LV S 60V 18V IB 90V 24V N.2 Front view - "Power Line" LED (lit when busbar voltage is On, see 14. The module also enables the relay powered. After performing dielectric stiffness test, restore the isolator its original position turning clockwise until you reach the opposite end stroke, because all the voltage protections are disabled while the isolator the test position. At the end the procedure, make sure that the Power line LED on.1 120/V-PR 120/LV EAS odule 14. 14.B. The measurements are sent the module the protection release, enabling the implementation set protection and measurement functions. 14.3) - Isolator Isolator \ A Before performing the dielectric stiffness test essential turn the isolator into the Test position mode turning the screw anticlockwise until you reach the end stroke position. The PR120/V-PR120/LV module does not need any connections made the customer.1 General characteristics The MEASURING module records and processes the voltages.
