Installation
Use shielded cable if wires are longer than 12 inches (30 cm) to avoid
picking up unwanted electrical noise.
It may be necessary to earth ground the shielded cable. If noise is
produced by devices other than the drive, ground the shield at the drive
end. If noise is generated by a device on the drive, ground the shield at the
end away from the drive. Do not ground both ends of the shield.
Do not bundle logic wires with power carrying wires that can cause
erratic operation. Keep logic wires in a conduit separated by at least 2
inches from power carrying wires. Do not allow logic wires to travel in
parallel to power carrying wires for more than 1 inch.
Line fusing
RG501A and RG511A drives have line fuses preinstalled to fuseholders
FU501 and FU502 (see Figure 3 for location). Factory installed line fuses
are rated for maximum rated horsepower. Resize line fuses if a lower rated
horsepower motor is used. Table 1 lists the recommended line fuse sizes.
Use fast acting fuses rated for 250 VAC or higher, and approximately
150% of the maximum armature current.
