Installation works were supposed to be performed in the territory of plant. The non-standard of the project consisted in the increased tension of a contact network — 500 volts. For implementation of intention it was required to process a design of blocks of a set, and also to modify program and the hardware.
After a while the set has been processed and sent for installation to electric locomotives. At the same time for installation works specialists of PAPALEO have left. After completion of mounting works and commissioning, electric locomotives have been delivered to the customer.
