;
To avoid lightning strike and incidence of electrocution, the external metal ground
wire for the electrical equipments must be thick and short and connected to the
ground terminal of the Hybrid servo driver system.
;
When multiple Hybrid Servo Controllers are installed together, all of them must be
directly connected to a common ground terminal. Please refer to the figure below to
make sure there is no ground loop.

Mains power terminals (R/L1, S/L2, T/L3):
;
Connect these terminals (R/L1, S/L2, T/L3) via a non-fuse breaker or earth leakage
breaker to 3-phase AC power (some models to 1-phase AC power) for circuit
protection. It is unnecessary to consider phase-sequence.
;
The wire between the three-phase AC input power supply and the Main circuit
terminals (R/L1, S/L2, and T/L3) must be connected to a non-fused switch.
;
Please make sure to fasten the screw of the main circuit terminals to prevent sparks
which is made by the loose screws due to vibration.
;
Verify the voltage of power supply and the associated maximum available current.
Please refer to Chapter 1 Descriptions of Specifications.
;
If the Hybrid Servo Controller is equipped with a leakage circuit breaker for leakage
protection, please select the circuit breaker that has a sensing current above 200mA
and action time over 0.1 second to avoid malfunction.
