3.2 - Terminal block layout
3.3 - Description of the terminal
blocks
3.3.1 - Power terminal block
The maximum tightening torque for the
power terminals is 1N.m for 0.5M to 5.5T(L)
ratings, 2N.m for 8T(L) to 27T ratings, and
15N.m for 33T to 50T ratings.
• 0.5M to 1.5M ratings
• 1.5M/TL to 3.5M/TL ratings
• Check that the braking resistors
are correctly connected between
the + and DBR terminals (and not + and -).
