Thermal safeguards
The battery back-up is equipped with a thermal safeguard protecting it against
overheating. This safeguard operates on two levels.
If the internal temperature reaches critical, it switches on an acoustic signal and
displays the appropriate message. The UPS continues to operate in its current mode.
If the temperature keeps rising and critical temperature is reached, an alert is
displayed and the UPS switches to EMERGENCY mode.
EPO
EPO (Emergency Power Off) is a mechanism that enables interrupting the
power supply to receivers connected to the battery back-up’s output in emergency
situations (such as fires). The UPS switches to the EMERGENCY mode.
There are two ways to trigger this mechanism:
- By opening the contacts of the external EPO connector (release),
- By forcing the mode from the user interface (KONTROLA 1/4;
AwaryjneWylaczenie).
Output voltage returns after the user resets the malfunction flag (KONTROLA 3/4;
KasujAwarie) and moves the release to its inactive setting (default state of the
release) in the case of external triggering.
It is possible to temporarily lock the EPO function out while the EPO release is
installed. The technician may then remove the EPO connector without fear of cutting
the power supply to receivers. This operation must be completed within 1 minute
from the moment of setting the control flag (KONTROLA 2/4; Czas.Wyl.EPO);
afterwards the lock is automatically removed.
Voltage on the EPO contacts is safe and it is separated from all the other systems of
the UPS.
WARNING! The EPO circuit must be self-contained and must not be
connected to any other installations.
Manual BYPASS
The battery back-up is equipped with a manual switch for the BYPASS line, which
enables direct switching of the BYPASS line to the output clamps of the UPS,
circumventing the back-up units.
