Be sure there is adequate clearance for air circulation around the user-supplied
enclosure. A 6-inch minimum clearance is required wherever vents are located in the
cabinet.
It is important to verify that plant power will meet the input power requirements of the
LiquiFlo 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, encoder 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 the size of conduit openings, and 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.
It is important to determine the size of the conduit openings in the cabinet that the
drive is mounted in so that the wire planned for a specific entry point will fit through the
opening.
Input power wiring should be copper and should be sized according to applicable
codes to handle the drive's continuous-rated input current. Output wiring should be
copper and should be sized according to applicable codes to handle the drive's
continuous-rated output current. See tables 3.3, 3.4, and 3.5 for recommended power
wire sizes. See figures 5.1 and 5.2 for input and output wiring connections.
