Getting started guide

Mounting and installation
The 670 IEDs are 6U high (265.9 mm) and are available in 1/2, 3/4 and 1/1 case
sizes for 19” racks. All IEDs fit into a 19” rack with the help of alternative
cover plates or with COMBIFLEX relays/cases, of type RHGS6 and RHGS12.
The mounting details are: side by side mounting plates (1) 1MRK 002 420-Z
when two relays or a relay and relay rack are mounted together. Mounting
brackets for a full 19” (2) 1MRK 002 420-CA. Cover plates with brackets for
19” mounting for 3/4 case size 1MRK 002 420-BA, and for 1/2 case size
1MRK 002 420-BB.
Alternatively the IED can be flush mounted. The IED can be ordererd with
optional IP 54 ingression protection.
Test switches and COMBIFLEX auxiliary relays can be mounted in separate
relay cases. The RHGS6 and RHGS12 types of cases can be used and bolted
together with the IED 670 to fill a relay rack. If the RTXP24 test switch is used,
mounting brackets for apparatus bars, ordering No. 1MRK 000 020-BT are
required. A suitable test switch with contacts for example for a line protection
IED such as REL 670 is selectable when ordering. This allows commissioning
and maintenance testing of the complete IED with many functions from one test
handle.
Note! The use of test switch RTXP24 NO contact 29-30 to perform software
blocking has several advantages and is used during testing of many functions in
the same protection IED.
Test is supported by the configuration TEST function block. Switching the IED
to test mode will allow blocking and releasing of individual functions sepa-
rately and also blocking of events to the SA system.
