— Installation in switchgear
Position All SACE Emax 2 circuit breakers can be floor mounted in a vertical position inside the switch- gear compartment. The E1.2 circuit breaker can also be installed in a horizontal position and wall mounted. Conve- niently, the screens of the Ekip Touch and Hi-Touch versions rotate to a horizontal view for key data when the E1.2 is installed horizontally. Insulation distances and connection The circuit breakers can be connected to the main power system using the most common configura- tions and dimensions of copper bars.
Power supply The Emax 2 circuit breakers can be supplied, from either the upper or lower terminals. In the event a measurement module is present, in order to make use of all information when the circuit breaker is in the open position, the voltage sockets must be in- stalled on the power supply side.
Installation of live parts must ensure: • Minimum insulation distances between the phases

1000V
The use of phase barriers is recommended for fixed version circuit breakers used in voltages over 480V.
