Mounting and connection
4.2.9 Instructions for connection
4.2.9.1 Transformers for the IT system
The power for group 2 medical locations is supplied via an isolating transformer. Observe the require-
ments of DIN VDE 0100-710 (VDE 0100 Part 710) for transformers for medical IT systems.
4.2.9.2 Temperature sensors
Bender IT system transformers are equipped with the temperature sensors required according to their
insulation class. These temperature sensors (maximum of 6 sensors connected in series) are connected
to terminals Z1 and Z2.
4.2.9.3 BMS bus
Ex works, terminals A and B are available for connecting BMS-enabled devices. Alarm indicator and test
combinations, alarm indicator and operator panels or other bus-enabled Bender devices can be con-
nected. The bus line must be terminated at both ends with resistors (120 Ω, 0.25 W). Please note the in-
formation in the "BMS bus" manual.
4.2.9.4 MK… alarm indicator and test combination,
TM… alarm indicator and operator panels,
CP9xx Touch Control Panel
MK2430, MK800, CP9xx and TM800 are used. They have the following tasks:
• Display alarms from the ATICS® transfer switching device
• Mutual monitoring for failure
• Test of the ATICS® functions: start insulation monitoring, load current measurement and tem-
perature monitoring and display the results.
4.2.9.5 SCADA systems (Supervisory Control and Data Acquisition)
If messages from the ATICS® transfer switching and monitoring device are to be forwarded to a SCADA
system, the following options are available:
• Protocol converters (gateways, e.g. COM465…)
• Common alarm via the ATICS® relay output
• Alarms via interconnected signal converters SMO480-12 or SMO482-12. TM800, SMO480-12
and SMO482-12 convert serial signals from Bender devices into potential-free relay contact
alarms.
4.2.9.6 EDS151 insulation fault locator (optional)
The EDS151 insulation fault locator is used in conjunction with the ATICS® transfer switching and moni-
toring device to locate insulation faults in unearthed power supplies (IT systems). With the six integrat-
ed measuring current transformers, it records the locating current signals generated by the ATICS® and
evaluates them accordingly. Several EDS151 insulation fault locators may be used simultaneously.
