The unit is intended for use on a DIN rail inside a switchboard with prevention of access of non-qualified
personnel. In case of access of non-qualified personnel, it is necessary to cover the terminals by means
corresponding to the environment of the unit operation. It is possible to make the user interface accessible to
the operation staff.
11.2.1 Endurance to the power supply voltage fails
MainsPro G99TT unit withstands the power supply voltages failures of 100 ms lengths in the full range of
power supply voltage on the 85 - 265 VAC / 110 - 370 VDC terminals and at the voltage 18 - 40 VDC
connected to the 8 - 40 VDC terminals. The construction of the power supply allows that the unit withstands
the voltage drop down to min 40 VAC in case that the unit was started from the AC voltage within the allowed
range 85 - 265 VAC. A permanent voltage drop to this level does not influence the unit operation.
