5Actuator power supply
We recommend the use of 2 independent power supplies so as to separate the power supply to the splitter boxes / sensors from the power supply to the actuators.
This configuration provides maximum protection against any disturbance on the outputs (short circuits).
Separating the splitter box/sensor (pin 4) power supplies means that the emergency stop can be connected to the actuator power supply (pin 5 of the 7/8" connector).
WARNING
RISK OF UNINTENDED EQUIPMENT OPERATION
Do not connect pin 4 of the power supply connector to the emergency stop circuit of the system. Interrupting the power supply to this pin, will deactivate the I/O channels of the splitter box, which can result in an unintended equipment operation.
Failure to follow this instruction can result in death, serious injury, or equipment damage.
