5.9.1 Converting transformer T1 from 120 VAC to 230 VAC
Transformer T1 (item 1 in Fig. 5 - 11) can be accessed from beneath the top part of the frame
(item 2 in Fig. 5 - 11
). 5
Loosen the four hexagon socket-head screws.
Pull the cover plate over the transformer housing down and off.

5.9.2 Replacing the fuse
There are two versions of the main power supply for the component trolley: 5
Replacing the fuse F1 on the old power supply 5
Here, the fuse is located on the primary side of transformer T1. The fuse F1 must be replaced (see
circuit diagram 00301239-040301LD4, page 212
) 5
Replace the fuse in the fuse holder in the cover panel:
old rating: 6,3 A T
new rating: 3,15 A T
Replace the adhesive label specifying 6.3 A with the 3.15 A label from the conversion kit.
Replace the cover panel over the transformer and tighten the four hexagon socket-head
screws.
New power supply 5
Here there are two fuses on the secondary side of transformer T1. The fuses do not have to be
replaced (see circuit diagram 00301239-060101LD4, page 213
) 5
Replace the cover panel over the transformer and tighten the four hexagon socket-head
screws.
5.9.3 Checking the protective wire connections
Check that the detached protective earth wires have been reconnected correctly.
5.9.4 Carry out the safety check to DIN EN 60 204
When the conversion is complete, carry out a safety check to DIN EN 60 204.
Follow the procedure described in section 2, page 146 onwards.

If the machine is operated with 208/120V (USA) please note:
1.) Connect the inrush current limiter A1 in parallel:
Grounding bolt
Front cover
Warning! Main power supply voltage!
If required, root the N conductor
via the main power switch. (IT net)

A note regarding the fine-wire fuses !
When any of the F5, F6,
F8 or F9 contactors has tripped, the micro-fuses F5.1, F5.2
or F6.1, F6.2 or F8.1 or F9.1 always
have to be checked.
