Step 4.

Mount the terminal strip (from cable assembly M/N

57C373) on a panel. The terminal strip should be mounted

to allow easy access to the screw terminals. Be sure that

the terminal strip is close enough to the rack so that the

cable will reach between the terminal strip and the

module. The cable assembly is approximately 60 inches

long.

Step 5.

Attach the resolver but leave the mechanical coupling

between the resolver and the motor unconnected.
Fasten the field wires from the resolver to the terminal

strip. Typical field connections are shown in figures 3.2

and 3.3.
Use twistedĆpair wire, connected as shown, for the cabling

between the resolver and the terminal strip in the control

enclosure. Recommended twistedĆpair wire is Beldent

9497 cable or equivalent. Maximum operating cable length

is dependent upon the type of cable you use.
Make certain that all field wires are securely fastened.
