For 6 and 10 kVA models, the manual bypass has an auxiliary

contact
labelled as EBMS, which has to be connected with
its homologous located in the UPS or stabilizer, where its mis-
sion 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 fol-
lowing the stated order.
Illustrations of Fig. 7 and/or 8 show how to connect the manual
•
bypass with a UPS or stabiliser and loads, depending on its
power rate.
Respect the stated input and output strictly, otherwise
the UPS or stabiliser, manual bypass and loads can be
damaged.
As this is an equipment with protection against elec-
•
trical shocks class I, it is essential to install the main
earth protection cable
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 entire system.
In 6 and 10 kVA bypass models.
Connect the main earth protection cable
[
]. There is a second terminal
minals. The earth protection cable to be connected to the
UPS or stabilizer can be taken from any of them.
