Spare parts

Plug-in unit

The relay's construction allows a spare part in form of a plug-in unit. The
outage time can therefore be reduced to a minimum in case the relay should
fail.
In case of malfunction, please consult your relay supplier.
The spare plug-in unit to be used for a certain relay is suitable if at least the
first 10 characters in the order number are identical with those in the order
number of the case.
To obtain identical functionality to those of the original product,
all characters in the order number, except for those indicating a
spare part, should match the ones in the order number of the
case.
The relay features a built-in mechanical coding system which allows that a
plug-in unit with voltage or current measuring inputs only can be plugged
into a corresponding case. This helps to prevent dangerous situations from
arising in case a non-suitable plug-in unit is fitted into a relay case.
Forcing a non-suitable plug-in unit into a case breaks the relay
and may cause dangerous situations.
The plug-in unit is calibrated as a whole to achieve the best possible operation
accuracy and individual pieces of it should not be removed.
If the faulty plug-in unit is subject to guarantee and the fault is caused under
circumstances covered by the conditions, it should be returned for repair.
Ordering of spare parts is done by using the same ordering system as for
ordering a new relay.
