Planning Before Installing
It is important to verify that plant power will meet the input power requirements of
the GV3000/SE drive's Power Module circuitry. Refer to table 2.1 for input power
rating specifications. Be sure input power to the drive corresponds to the drive
nameplate voltage and frequency.
Certain drive requirements should be checked before continuing with the drive
installation. Wire sizes, branch circuit protection, speed feedback (for FVC
regulation), and E-stop wiring (see chapter 7), are all areas that need to be
evaluated.
The terminal strip on the Regulator board provides terminals for 24 VDC power for
the eight remote control inputs. Refer to tables A.3 and A.4 for control input and
output specifications.
Wire size should be determined based on applicable local, national, and
international codes (e.g., NEC/CEC regulations).
ATTENTION: The user is responsible for conforming with all
applicable local, national, and international codes. Failure to observe
!
this precaution could result in damage to, or destruction of, the
equipment.
Input power wiring should be sized according to applicable codes to handle the
drive's continuous-rated input current. Output wiring should be sized according to
applicable codes to handle the drive's continuous-rated output current. See tables
3.3 and 3.4 for recommended power wire sizes.
Important: Use only copper (Cu) wire with a temperature rating of 60/75°C.
