• AC/DC sensitive residual current monitoring in earthed two, three or four conductor
systems (TN and TT systems)
• Monitoring of variable-speed drives, UPS systems, construction site equipment, printing
machines, battery systems, laboratory equipment, wood working machines, MF welding
systems, furniture industry, medical electrical equipment, etc.
• AC/DC sensitive current monitoring of, in the normal case, de-energised single conductors
(e.g. N and PE conductors)
Description:
1 - External supply voltage used to power device
2 - Wiring diagram for a three-phase system. Only two connections
to the system are necessary to monitor all three phases.
3 Wiring diagram for a single-phase system
4 - Wiring diagram for a DC system
5 - Equipment ground connections
6 - External test button (normally open contact)
7 - External reset button (normally closed contact). When the
terminals are open, the fault message will not be stored.
8 - Standby contact. When the contact is closed, no insulation
measurements take place.
9 - IRDH275: Analog output, electrically isolated: 0 - 400 µA
IRDH275B: Analog output, electrically isolated:
0 - 20 mA or 4 - 20 mA
10 - RS-485 interface:
IRDH275: One-way ASCII stream with measurement status
IRDH275B: Two-way communication with other BENDER
devices, including communication gateways
11 - Alarm relay 1, normally energized or de energized contact
12 - Alarm relay 2/System Fault Relay, normally energized or deenergized
contact
