Version 1.0
Notes:
•
Motor lines connected to contactors (U, V and W) are bridged between set of contactors.
•
Unused lines must be isolated from ground, properly connected and secured behind contactors.
4.
According to voltage requirement connect both sets of lines (thicker and thinner) K1 - K2 - K3 - K4 - K5 - and
K6 as described above.
5.
Locate black triple voltage power transformer next to contactors. Unplug input (1 wire/line) and plug
according to voltage requirement. 220, 380 and 440V are displayed on transformer.
6.
Only for M5 units: verify and replace rectifier with corresponding voltage. For voltages ranging 300~555V use
rectifier model RH555 UHT 555V~0.75A For voltages ranging 198~270V use rectifier RB270 UHT 270V~0.75A
7.
Ensure connections tightened, unused motor K lines must be isolated from ground and properly connected
as described in point 3.
8.
Properly set electric box cover.
9.
Remove previous voltage tags and marks.
10.
Replace voltage tags and marks with corresponding new voltage selected.
11.
Remove lockout/tagout and perform all corresponding inspection and testing as described in ASME
B30.16-2.

1.
Open electric box metal cover.
2.
Locate 12 black lines coming from motor labeled with yellow tags as: High Speed: 6 thicker lines K1 - K2 - K3
- K4 - K5 and K6. Low Speed: 6 thinner lines K1 - K2 - K3 - K4 - K5 and K6.
3.
Preset black voltage wires/lines connect as follows and repeat for thicker (High Speed) and thinner (Low
Speed) lines:
