REM 610 can be flush mounted, semi-flush mounted, mounted in a rack or wall
mounted. You will need separate mounting kits for the different methods except for
the flush-mounting method.
The relay’s construction with a detachable plug-in unit allows an easy installation.
Before mounting the relay, the plug-in unit has to be detached from the relay case.

Prior to detaching the plug-in unit from the case, the auxiliary voltage must be
disconnected.To detachtheplug-inunit,liftthelowerhandleuntilthe spring-loaded
locks on both sides of the handle are released and the unit is pushed about 6 mm out
of the case. This will separate the connectors and you can easily pull the unit out of
the case.
The relay features an automatic short-circuit mechanism in the current transformer
(CT) connector. Therefore, detaching the plug-in unit will not open the secondary
circuit of the CT which otherwise could cause dangerously high voltages.
Signal connectors will be left open when the plug-in unit is detached.

Before fitting a relay plug-in unit into a relay case, check that the unit and the case
have the same order number. The order number of the case is printed on the bottom
plate inside the case. However, if a substitute plug-in unit has to be used instead of
the original unit, ensure that at least the first ten characters in the order numbers of
the case and the plug-in unit are identical, as in the following example:
In order to obtain the identical functionality to that of the original product, all
charactersinthe ordernumber,exceptforthoseindicatinga sparepart,shouldmatch
the ones of the case.
Order number of the relay case 5(0$+CMP
Order number of the plug-in unit 5(0$+CNR
