For 6 and 10 kVA models, the manual bypass has an aux-
iliary contact 10 labelled as EBMS, which has to be con-
nected with its homologous located in the UPS or stabilizer,
where its mission has been previously described.
The risk of short-circuit is increased in case of
wrong manoeuvring, when the UPS or stabilizer do
not have this contact or it has not been connected. Make
the steps following the stated order.
•
Illustrations of Fig. 7 and/or 8 show how to connect the
manual bypass with a UPS or stabiliser and loads, de-
pending on its power rate.
Respect the stated input and output strictly, other-
wise the UPS or stabiliser, manual bypass and loads
can be damaged.
•
As this is an equipment with protection against
electrical shocks class I, it is essential to install the
main earth protection cable [ ] .
ˆ
In 3 kVA bypass models.
The bypass power supply plug will be connected to a
wall outlet with protection earth duly installed, which
through the IEC connectors will be connected to the en-
tire system.
ˆ
In 6 and 10 kVA bypass models.
Connect the main earth protection cable 5 to the ter-
minal [ ] . There is a second terminal 5 beside the
output terminals. The earth protection cable to be con-
nected to the UPS or stabilizer can be taken from any
of them.
