Ground

1)

Ground must be done before operating the positioner.

2)

Open terminal cover and there is an internal ground bolt on the left of terminal plate. When using

internal ground, use 2 mm wrench to loosen locking bolts of the terminal box cover. An external

ground bolt is located next to the conduit entry. Please make sure that the resistance is less than

100ohm.

3)

When using external ground, use (+) screw driver to unscrew the ground bolts. Insert external

ground bolts and spring washer into ring type terminal of the ground cables and tighten them with

bolts.
