varimeter
0222131
• For rooms that are used for medical purposes, in accordance
with VDE 0107
• According to IEC 60 364-7-710, IEC 61 557-5, IEC 61 557-8
• For exclusively three-phase and alternating current voltage supply
systems, IT system
• Choice of fault actuation via slide switch for R AN = 75 or 50 kΩ
• Additional monitoring of 2 independent 24 V alternating current
supply systems possible via terminals X3, X4,
RAN = 100 kΩ, e.g. for operating theatre lights
• LED indicators to indicate readiness for operation, insulation
status and contact position
• Output: 2 changeover contacts
• Closed circuit principle
• Test pushbutton to determine whether the unit is working properly
• Connection of max. 4 UP 5862 test and reporting combinations
• External cancel pushbutton can be connected to terminals LT1, LT2
• Width 105 mm
