General Precautions
replace the User Manual and is
ATTENTION:
time to discharge after removal of mains supply. Before working on
!
drive, ensure isolation of mains supply from line inputs [R, S, T (L1,
L2, L3)]. Wait three minutes for capacitors to discharge to safe voltage
levels. Failure to do so may result in personal injury or death.
Darkened display LEDs is not an indication that capacitors have
discharged to safe voltage levels.
ATTENTION:
if this parameter (A092 [Auto Rstrt Tries], A094 [Start At PowerUp]) is
!
used in an inappropriate application. Do not use this function without
considering applicable local, national and international codes,
standards, regulations or industry guidelines.
ATTENTION:
frequency AC drives and associated machinery should plan or
!
implement the installation, start-up and subsequent maintenance of the
system. Failure to comply may result in personal injury and/or
equipment damage.
ATTENTION:
sensitive parts and assemblies. Static control precautions are required
!
when installing, testing, servicing or repairing this assembly.
Component damage may result if ESD control procedures are not
followed. If you are not familiar with static control procedures,
reference A-B publication 8000-4.5.2, “Guarding Against Electrostatic
Damage” or any other applicable ESD protection handbook.
