Connect the input cables and install the shrouds (option
+B051)
See
Step-by-step drawings for an installation example of standard drive configuration in
Rittal VX25 800 mm wide enclosure
Step
Tasks (input cables)
1
Ground the input cable shields (if present) 360 degrees at the enclosure entry.
2
Connect the twisted shields of the input cables and separate ground cable (if present) to the enclosure
grounding busbar.
3
Step drill carefully sufficiently big holes to the entry clear plastic shroud for the cables to be 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 enclosure 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 option +H370: Connect the input cable conductors to the drive module
L1/U1, L2/V1 and L3/W1 connection busbars, Go to step 12.
Tasks with option +H370: Do steps 6 to 11.
6
Screw in and tighten the insulators to the drive module by hand. Install the L1/U1 connection ter-
minal to the insulators.
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 side clear plastic shroud and the upper front cover of the drive module.
13
Install the entry clear plastic shroud (option +B051) and motor cable shroud (option +B051).
14
Install the top clear plastic shroud (option +B051) to the drive module.
(page 105).
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.
