; Never connect the Hybrid servo drive output terminals U/T1, V/T2 and
W/T3 directly to the AC mains circuit power supply.
; DO NOT use Hi-pot test for internal components. The semi-conductor
used in Hybrid servo drive easily damage by high-voltage.
; Even if the 3-phase AC motor is stop, a charge may still remain in the
main circuit terminals of the AC motor drive with hazardous voltages.
; Only qualified persons are allowed to install, wire and maintain AC motor
drives.
; When the Hybrid servo drive uses an external terminal as its source of
operation commands, the motor may start running immediately after the
power is supplied. In this case, it may be dangerous to any on-site
personnel.
; DO NOT install the Hybrid servo drive in a place subjected to high
temperature, direct sunlight, high humidity, excessive vibration, corrosive
gases or liquids, or airborne dust or metallic particles.
; Only use Hybrid servo drives within specification. Failure to comply may result in
fire, explosion or electric shock.
;
When the motor cable between Hybrid servo drive and motor is too long,
the layer insulation of the motor may be damaged. Please add an AC
output reactor to prevent damage to the motor. Refer to appendix A
Reactor for details.
; The rated voltage for Hybrid servo drive must be ≤ 240V (≤ 480V for 460V
models) and the mains supply current capacity must be ≤ 5000A RMS
(≤10000A RMS for the ≥ 40hp (30kW) models).
