3.4 CONNECTION OF THE BREAKER OPERATING MEC HANISM.
3.4.1 SAFETY REGULATIONS.
• The case must be grounded.
• Warning! Do not short-circuit or touch the auxiliary voltage.
Use of touch-protected connectors is required for personal safety.
• The inputs for coils “Uc” and motor “Um” are not fused!
Make sure that the powers to these inputs are pre-fused with maximum 32A.
• Never do any work on a circuit breaker unless the control circuits of the breaker are disconnected from the SA10A
control outputs. (avoiding unintentional breaker operations)
Note!
The white 4 mm panel socket "ISOL" is an isolated connection that can be used to disconnect the control circuits of the
breaker.
3.4.2 CONNECTION OF OPE RATING COILS.
See figure 2.6
• Connect the input coil voltage to the inputs Uc and COM.
Connection to COM is optional and is only used for monitoring the voltage.
• Connect the positive connection of the closing coil and the positive connection of the opening coil to the outputs
CLOSE and OPEN.
• Connect the negative connections of the operating coils to the negative connection of the coil voltage.
3.4.3 CONNECTION OF MOT OR.
See figure 2.6
• Connect the auxiliary voltage to the inputs Um and COM
• Connect the motor connections to the output MOTOR and to the negative connection of the auxiliary voltage.
Note!
The connection of the motor circuit is optional and is only necessary for monitoring the voltage and current
