1 ISL Insulation monitoring devices Continuous monitoring of IT systems from photovoltaic to industrial applications.

2 Ensuring operational continuity To ensure the operational continuity of an electrical system, IEC Standard Low-voltage electrical installations Protection for safety Protection against electric shock requires the system protection from direct and indirect contacts, according to the methods shown in the table. Among all the protection methods identified by the Standard, only IT distribution systems can guarantee greater operational continuity in case of a first fault to earth: in these systems, the circuit-breaker will not trip because the fault current is limited by the high insulation impedance. The IT distribution systems shall avoid the loss of production and ill service that power supply interruption could cause. Protection + operational continuity = IT System The first fault to earth should be immediately recovered, because a second fault to earth would cause the tripping of the protection devices (miniature circuit-breakers or residual current circuit-breakers), interrupting the power supply. The Standard requires the installation of an insulation monitoring device to signal the first fault, in order to avoid a second fault that could compromise the required operational continuity. IT System = Insulation Monitor ISL range performs continuous monitoring of IT systems insulation, in order to prevent any faults that may reduce operational continuity and, as a result, the efficiency of the system. Against direct Against indirect Against direct and indirect contacts contacts contacts Extra low-voltage provided by SELV, LV, FELV Class II components Non-conductive locations Earth-free local equipotential bonding Electrical separation Insulation of conductive parts Barriers or enclosures Obstacles Placing out of reach Residual current circuit-breakers Non essential operational continuity Essential operational continuity TN, TT systems IT systems

3 What s new ISL range allows monitoring and protection in the most demanding application environments. In particular, ISL-C 600 is suitable for large-sized industrial plants, such as refineries, iron, steel and petrochemical companies, whereas ISL-A 600 is used in the photovoltaic plants to monitor the insulation of IT lines downstream the inverter. ISL-C 600 ISL-A 600 Insulation monitoring up to 000 V a.c., in case of three-phase IT systems with accessible neutral Double monitoring threshold for more effective fault prevention Fail safe double relay for effective system control and timely monitoring, even in case of supply failure Instant display of insulation level Test and Reset can be remotely operated by a pushbutton Visual indication of the network status Insulation monitoring of IT systems up to 600 V d.c. Wide tripping threshold adjustment Fail safe relay for timely monitoring, even in case of supply failure Test and Reset can be remotely operated by a pushbutton Visual indication of the network status and indication of the faulty polarity Plenty of benefits Operational continuity When installed in an IT network, the insulation monitoring device continuously controls insulation. In case of first fault, it gives warning about the first fault in order to recover it before the miniature circuit breakers interrupt the power supply. Fault prevention ISL gives warning when insulation drops below a set value, preventing greater damages to the network. Greater efficiency Thanks to TRIP and ALARM thresholds the fault can be managed even before it actually occurs, therefore preventing service interruption. In addition, the unit can be tested and reset remotely by means of a pushbutton. 60 monitoring ISL range controls a wide variety of IT systems, providing protection to photovoltaic installations, industrial installations, supervision systems, data centers and other applications. Cutting maintenance costs and inefficiencies Thanks to a continuous and timely monitoring of the system, scheduled maintenance operations can be reduced together with overhead costs. Immediate installation Quick fixing thanks to mm DIN rail mounting. The front microswitches are preset on the most commonly used settings.

4 Applications Control room data line protection ISL-MOT 000 In the electrical distribution systems that provide power supply to critical applications, ISL insulation monitoring devices ensure a prompt detection of any type of leakage that may be dangerous for the network. Safety lighting Data lines Mobile equipments Movie sets TV or radio installations ABB offers a whole range of insulation transformers, TM-I range, to create an IT network.
