3.1.4 Transportation Type of Cabinets
Carrying vehicles or handling accessories must have enough features and characteristics to
carry UPS’s weight.
Cabinet is equipped with four-wheel. Thanks to this feature, it can be moved easily. These
wheels must be used only on smooth surfaces.
The front side wheels of UPS must be locked after positioning properly. The back side wheels are
fixed. Be more careful of sudden movements, especially when batteries are inside of cabinet.
Move the UPS as rarely as possible.
3.1.5 Mains, Load and Battery Connections
Makelsan strictly recommends a distribution board for the UPS outputs. Proper fuses and
breakers must be used in such distribution board. A-B type fuses or magnetic breakers are
recommended if the load is suitable.
3.1.5.1 External Protection
To protect the AC inputs, thermal magnetic breakers or V type breakers must be installed on the
distribution board.
Over current protecting must be installed on mains input distribution board and fuses must be
chosen 135% higher rated than the ones given in the table below. Fuses must be C-type.
Ground leakages flow to the ground through the EMI filters on the input and the output of the
UPS. Makelsan recommends the use of 700mA rated relays for handling leakage currents.
Those relays must also be:
Resistant to both positive and negative DC pulses,
And not sensitive to transient currents.
Must be sensitive to currents which is average between 0,3-1 A.
