Precautions
Mounting
Do not apply excessive torque to the mounting nuts of the E2C-X or
E2C-C20MA. Be sure to tighten each nut with a toothed washer.

Mutual Interference
When mounting more than two E2Cs face to face or side by side,
ensure that the minimum distances given in the following table are
maintained. Except for the E2C-CR5B, E2C-C20MA, and
E2C-G
j
4A, mutual interference can be prevented with the setting
of the cable length selector of each model. This, however, changes

normally after cable length change.
