2.4.3 Wiring connections for EL7-EC series servo drives
EL7-EC series servo drive supports single phase and three phase 220VAC. Only
driver with power rating above 1500W supports three phase 220VAC.
Please use a circuit breaker for the main power supply to prevent damage to the
product or machine.
Please do not use a contactor in connection to servo motor as it may not withstand
a sudden surge of operating voltage.
Please take note of the capacity when connect to a 24VDC switching power supply,
especially if power supply is shared between multiple components. Insufficient
supply current will cause failure in holding brake functions.
