Getting Started
3.1 Unpacking and Repacking
3.2 Checking the Rated Data
30
The protection system is packaged at the factory to meet the requirements of IEC
60255-21.
Unpack and pack the devices with normal care, without using force, and with appro-
priate tools.
Visually check the device immediately upon arrival for correct mechanical condition.
Please observe the instruction leaflet and any other documentation that may be part
of the delivery.
Check also that the accessories included in the delivery are complete.
(Table A-4, page 330).
You can use the transport packing in the same manner for further shipment. Storage
packaging alone, for individual devices, is not sufficient for shipping. If you use other
packaging, make sure that the shock requirements under IEC 60255-21-1 Class 2
and IEC 60255-21-2 Class 1 are met.
Note
The device must be in the final operating area for a minimum of two hours before the
power source is first applied. This time allows the device to attain temperature equilib-
rium, and dampness and condensation to be avoided.
First of all, check the complete ordering code (MLFB) of the system to ensure that the
version delivered complies with the required rated data and functions.
The complete ordering code can be found on the rating plates on the back of the hous-
ings. The meaning of its digits is shown in Appendix Chapter A.1, page 328. The most
important point is the matching of the rated device data to the station ratings, such as
rated auxiliary voltage and rated currents of the CTs. This information is also found on
the rating plate.
