The electronic circuits reduced by M.S. are completely safe from electrostatic discharge (8 KV IEC 255.22.2) when housed in their case; withdrawing the modules without proper cautions expose them to the risk of damage. Copyright 2010 - Microener Firmware: 2.0X... -

F(I>)=D (see § 12). On the contrary the current unbalance element F46 operates properly even at low-frequency because the heating of the rotor produced by the negative sequence component is by itself inversely proportional to the frequency. Copyright 2010 - Microener Firmware: 2.0X... -

Page 14: Output Relays
- The relays R1,R2,R3,R4 are normally deenergized (energised on trip): these output relays are user programmable and any of them can be associated to one of the IM30-GLF's functions. One relay eventually associated to the instantaneous element of one of the functions, after pick-up normally drops-out as soon as the tripping cause disappears (current below the set trip level). -
