unit:
connection of the input and output:
•
for models up to 3 kVA: input via cable with plug, connectable to the UPS
through an iEC connector. output through iEC connectors.
•
for models with power ratings higher than 3 kVA: Terminals for powering the
device and loads. it is necessary to remove the transparent protective cover to

•
USb to operate the UPS as a PC peripheral device.
•
digital input and output (only models > 3 kVA).
•
Connection with external EPo button.
•
Auxiliary contact for the manual bypass switch (only models > 3 kVA).
•
