All IForce linear servo motors are high potential (high-pot) tested to 775 Volts phase-to-phase, and phase-to-ground.
Elevated high-pot testing of up to 1800 Volts is available as a custom option. It is recommended that only the high-pot level needed be tested. The higher the voltage, the more destructive the test is to the insulation of the coil.
