Note!
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:
Order number of the relay case
Order number of the plug-in unit
In order to obtain the identical functionality to that of the original product, all
characters in the order number, except for those indicating a spare part, should match
the ones of the case.
The relay features a built-in mechanical coding system which helps to prevent
dangerous situations from arising, should a non-suitable plug-in unit be fitted into a
relay case.
Danger!
!
Forcing a non-suitable plug-in unit into a case will break the relay
and may cause dangerous situations.
When installing a plug-in unit into a case, first check that the handle is down in its
initial position and then push the unit into the case until the locks click; see the figure
below.

Be careful not to drop the battery inside the plug-in unit. Insert a new battery under
the battery holder and ensure that you install the battery with the correct polarity to
avoid damage to the equipment.
