HAKEL ISOLGUARD HIG-IFL1 insulating monitoring device with fault location is a system designed for comprehensive insulating status monitoring of single-phase insulated IT systems in the health sector.
Primary version of the HIG-IFL1 allows to monitor 8 power circuits. This number can be increased by 4 or 8 circuits using expansion module. Maximum number of monitored circuits is 32. The interconnection line between the individual devices must be conducted within a single switchboard.
Expansion module HIG-IFL/EXP8 allows to monitor another 8 circuits.
HIG-IFL1 together with expansion modules enables monitoring systems that are designed and operated in accordance with standards IEC 60364-7-710:2002 (electrical installations at healthcare facilities), IEC 61010-1:2010, IEC 61557-1:2007, IEC 61557-8:2007, IEC 61557-9:2009 up to 275 V AC maximum operating voltage to be monitored.

Basic characteristics
 Expansion module for ISOLGUARD HIG-IFL1 produced by HAKEL
 Insulation status fault location of AC systems with 0 to 275 V voltage
 Expands number of fault location evaluation circuits by another four or eight individual circuits
 Parameters measured by expander are displayed on the HIG-IFL
 Separate supply voltage also allows to monitor IT power supply system, which is not under voltage
 Optional connection of MDS-D and MDS-DELTA remote monitoring modules
 MDS-D module displays number of IN input with insulation status fault
 Module of the rack case 19″ standard 1U height
