Verifying the Site Provides for Recommended Air Flow Clearances
Be sure there is adequate clearance for air circulation around the enclosure. A
6-inch minimum clearance
is required wherever vents are located in the cabinet.
Verifying Power Module Input Ratings Match Supplied Power
Verify that plant power meets the input power requirements of the power module
circuitry for the LiquiFlo 2.0 drive. See
Table 2 on page 24 for input power rating
specifications. Be sure input power to the power module corresponds to the
nameplate voltage, current, and frequency of the power module.
Wiring Requirements for the
Drive Evaluate the input power wire sizes, branch circuit protection, and control wiring
before continuing with the drive installation (
Chapter 6 ).
Determining Wire Size Requirements
Determine wire size based on current requirements, size of conduit openings, and
applicable local, national, and international codes (for example, NEC/CEC
regulations).
Conduit Entry Opening Sizes
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.
Recommended Power Wire Sizes
Use copper input power wiring that is sized according to applicable codes to
handle the continuous-rated input current of the drive. Use copper output wiring
that is sized according to applicable codes to handle the continuous-rated output
current of the drive.
Recommended Control and Signal Wire Sizes
The recommended wire size to connect I/O signals to the control terminal block
is 4 mm
2
(12 AWG). Recommended terminal tightening torque is 0.8...1 N•m
(7...9 lb•in).
ATTENTION: You are 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.
