SOLA 4000 - Operating Manual
Earth leakage protection: this device has a high leakage current
towards protective earthing. The maximum earth leakage current is
300 mA. When setting the threshold of the earth leakage circuit
breaker installed upstream from this equipment consider this
amount of current and that due to the loads.
All primary power switches installed downstream of the UPS must
be labelled as follows: "Isolate UPS (Uninterruptible Power Supply)
before working on this circuit.
The unit is provided with the E.P.O. (Emergency Power Off)
function. This function is activated by pressing simultaneously the
two push buttons on the bottom part of the Front Panel. This
function provides UPS disconnection from the load and from the
battery. Dangerous voltages will still be present inside the unit, if a
shunt-trip of the input supply switch is not provided for.
During electrolysis, batteries release hydrogen gas. There is a risk
of an explosion if the amount of hydrogen in the battery room
becomes too high.
Ensure appropriate ventilation of the battery
room according to the standard EN50091-1, to prevent the risk of
an explosion.
