Installation example of the standard drive module configuration 135
3 Connect the twisted shields of the motor cables to the grounding terminal.
4 Screw in and tighten the insulators to the drive module by hand. Install the T3/W2 connection
terminal to the insulators.
WARNING! Do not use longer screws or bigger tightening torque than given in the
installation drawing. They can damage the insulator and cause dangerous voltage to
be present at the module frame.
5 Connect the phase T3/W2 conductors to the T3/W2 terminal.
6 Install the T2/V2 connection terminal to the insulators See the warning in step 4.
7 Connect the phase T2/V2 conductors to the T2/V2 connection terminal.
8 Install the T1/U2 connection terminal to the insulators. See the warning in step 4.
9 Connect the phase T1/U2 conductors to the T1/U2 terminal.
10 Remove the plastic sheeting from the output clear plastic shrouds from both sides.
11 Install the shrouds to the drive module.
12 Install the lower front cover to the drive module.
Step Task (input cables)
1 Ground the input cable shields (if present) 360 degrees at the cabinet entry.
2 Connect the twisted shields of the input cables and separate ground cable (if present) to the cabinet
grounding busbar.
3 Step drill carefully sufficiently big holes to the entry clear plastic shroud for the cables to the
connected. Align the holes in the vertical direction according to the alignment holes in the shroud.
Smooth the hole edges.
Remove the plastic sheeting from both sides of the shroud.
Attach the cables firmly to the cabinet frame to prevent chafing against the hole edges.
4 Put the conductors of the input cables through the drilled holes in the clear plastic shroud.
5 For drive modules without H370: Connect the input cable conductors to the drive module
L1/U1, L2/V1 and L3/W1 connection busbars, Go to step 12.
For H370: Do steps 6 to 11.
6 Screw in and tighten the insulators to the drive module by hand. Install the L1/U1 connection
terminal to the insulators.
WARNING! Do not use longer screws or bigger tightening torque than given in the
installation drawing. They can damage the insulator and cause dangerous voltage to
be present at the module frame.
7 Connect the L1/U1 conductors to the L1/U1 connection terminal.
8 Install the L2/V1 connection terminal to the insulators. See the warning in step 5.
9 Connect the L2/V1 conductors to the L2/V1 connection terminal.
10 Install the L3/W1 connection terminal to the insulators. See the warning in step 5.
11 Connect the L3/W1 conductors to the L3/W1 connection terminal.
12 Install the entry clear plastic shroud. Install the front clear plastic shroud and upper front cover.
Remove the cardboard protective covering from the drive module air outlet.
13 Install the side and top clear plastic shrouds to the drive module.
