Conditions of wiring and operation of UPS for feeding a control system
and electronic part of V-line dispensers
1. All the cooperating electronic circuits of the control system and dispensers must be
connected to the UPS and for this point of view they are considered as a closed
electronic unit.
2. The control system and electronic instruments of dispensers connected to it as
a closed electronic unit must be connected only to one source of UPS.
3. The feeding of perhaps even a part of the system from another source is not
permitted.
4. A parallel cooperation of more UPS on one system is not permitted.
5. "Live" conductors of control system supply circuits and dispenser electronic
equipment must be galvanic-separated from the mains and even from protective
conductors – a system of "swimming zero" is created.
6. To comply with the requirement under item 5, the proper UPS must have galvanic-
separated input and output circuits.
7. For feeding of electronic system of the filling station, the UPS of ON LINE type must
be used exclusively.
8. For the correct function of UPS, the size of permanently installed load representing
max. 60 % of nominal UPS output, must be provided.
9. To the stabilized voltage circuits, no other consumers that are not a part of
prescribed technology, can be connected.
10. Therefore the sockets of stabilized voltage must be marked by the description e.g.
"Control system feeding".
11. The protection of input circuits of UPS must be dimensioned so that UPS feed outage
and total battery discharge did not occur under standard equipment function.
