Step

Ground the input cable shields (if present) 360 degrees at the cabinet lead-through.

Connect the twisted shields of the input cables and separate ground cable (if

present) to the cabinet grounding busbar.

For option +B051:

• Step drill carefully sufficiently big holes to the lead-through 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.

For option +B051: Put the conductors of the input cables through the drilled

holes in the clear plastic shroud.

Connect the input power cable conductors to the L1/U1, L2/V1 and L3/W1

connection busbars.

For option +B051: Move the lead-through clear plastic shroud along input

cables to its final position. Install the front clear plastic shroud.

1. Ground the outer shields of all external control cables 360 degrees at the cabinet lead-

through.

2. Ground the pair-cable shields of external control cables to a grounding clamp below

the control unit. Leave the other end of the shields unconnected or ground them

indirectly via a high-frequency capacitor with a few nanofarads, eg, 3.3 nF / 630 V.

3. Connect the conductors to the appropriate terminals of the control unit. See page 13.

4. Wire the optional modules if included in the delivery.
