Quickstart manual
ATTENTION! Filter power capacitors conserve the charge hazardous to
life within 5 minutes after de-energization! Prior to execution of work
inside the cabinet make sure that capacitors are de-energized. Filter
power capacitors conserve the charge hazardous to life within 5
minutes after de-energization!
ATTENTION! It is prohibited to disconnect and connect detachable
joints if supply voltage is available. Electronic control units of Variable
Speed Drives contain components made on the basis of metal-oxide-
semiconductor (MOS) technology excluding the action of static
electricity. If you need to touch some MOS component, ground your
body and the tools to be used.
Safety Recommendation
The drive must be installed, adjusted and serviced by qualified electrical
maintenance personnel. Improper installation or operation of the drive may cause
injury to personnel or damage to equipment. The drive must be installed and
grounded in accordance with local and national electrical codes. There is a deadly
level of voltage in drive’s
cabinet. Extreme care must be taken to ensure all power
sources are disconnected before starting installation, maintenance and repair
jobs. Whenever a drive containing a SCADA or telemetry connection is to be re-
paired or serviced, the service man must disconnect any communication devices
attached to the drive to prevent unexpected start commands from the remote
control system. Service men must be aware that there could be more than one
remote telemetry connection and that all of them must be disabled or discon-
nected for the duration of the repair period. Once repairs are completed, the te-
lemetry connections must be reestablished.
Personal Protective Equipment (PPE)
The basic personal protection equipment (PPE) required for field service in-
cludes, but is not limited to, steel toe shoes, safety glasses and a hard hat. If elec-
trical configuration or maintenance is performed on potentially energized circuits,
personal protective equipment is required to minimize the danger or electrical
shock, arc flash and/or arc blast. The level of PPE required can vary based upon
the available electrical energy available at the installation site. If any doubt exists,
consult and employ the recommendations published in the National Fire Protec-
tion Code, NFPA-70E.
Safety Procedures
Work inside the cabinets must be performed with the power off. Isolate energy
source(s) and use proper Lock Out/Tag Out (LOTO) procedures and Personal Pro-
tective Equipment (PPE) to ensure personnel safety. The drive also contains
stored sources of energy in the form of capacitors. Allow sufficient time after
power is removed for those capacitors to discharge to a safe level below 50 V DC.
The bleed resistors attached to the capacitors reduce the voltage to safe levels
