LiquiFlo 1.5 AC Power Modules, Hardware Reference Version 1.2
3.2.1.4 Recommended Motor Lead Lengths
Motor lead lengths can total up to 76 meters (250 feet).
3.2.2 Selecting Input Line Branch Circuit Fuses
Input line branch circuit protection fuses must be used to protect the input power lines.
See figures 5.1 and 5.2 for typical AC input/output connection diagrams..
Recommended fuse values are shown in table 3.6. The input fuse ratings listed in
table 3.6 are applicable for one drive per branch circuit. No other load may be applied
to that fused circuit.
3.2.3 Verifying Power Module Output Current Rating Is Greater Than
Motor Full Load Amps
Verify that the LiquiFlo output current rating is equal to or greater than the motor’s full
load current (amps). Table 2.1 lists the output current values.
!
ATTENTION: Most codes require that upstream branch circuit protection
be provided to protect input power wiring. Install the fuses recommended
in table 3.6. Do not exceed the fuse ratings. Failure to observe this
precaution could result in damage to, or destruction of, the equipment.
