RBENDER Insulation monitoring device with coupling impedance ZE420 Device features • Monitoring of the insulation resistance RF to earth • Monitoring of the battery voltage Un between the terminals "L+" and "L-" • Configurable measuring frequency for adjustment to the physical characteristics of the battery • Measuring the DC residual voltages UL+e (L+ to PE) and UL-e (L- to PE) • Selectable start-up delay, response delay and delay on release • Alarm output via LEDs ("AL1", "AL2"), display, and alarm relays ("K1", "K2") • Automatic device self test • Selectable n/c or n/o relay operation • Measured...

Functional description The isoBAT425 ISOMETER® is intended for monitoring the insulation resistance RF as well as the voltage Un of a battery during its assembly from individual battery cells. The ISOMETER® measures the insulation resistance RF and the system leakage capacitance Ce of the battery to earth. Additionally, it measures the battery voltage Un between L+ and L–, as well as the residual voltages UL+e (UL+ to earth) and UL–e (UL– to earth). In the case of open battery strings, the ZE420 coupling impedance provides a low-resistance connection (10 kΩ) between terminals “L+” and “L−”, necessary...

Only use 60/75 °C copper lines. For UL and CSA applications: Connect the supply voltage via 5 A fuses. For details about the conductor cross sections required for wiring, refer to chapter Technical data.
