CONNECTIONS TO THE A.C. SHARING REACTORS
Dependent upon the variant, connections to the a.c. terminals should be made with M10 or M12 bolts. The a.c
terminals are identified as:
•
U, V & W or
•
A, B, & C
For a given phase, the cable lengths from the DELTA transistor module to sharing reactor must be the same on
each DELTA module.

CONNECTIONS TO FLOOR MOUNTED REACTORS
Connections to floor mounted reactors will vary dependent upon the application. Refer to the circuit diagrams
provided by the drive designer, and Appendix C: Recommended Torque Settings
The chassis of the reactor must be connected to earth

SWITCH MODE POWER SUPPLY
Each DELTA transistor module requires an SMPS module to be fitted.
NOTE:
If an MVC3003-4020 or MVC3003-4030 SMPS unit is to be used, it MUST be fitted to DELTA 1.
See Section 2: Specification for DELTA identity information.
See Section 3.8.1.1 for Over-voltage Trip link settings.
The SMPS unit is mounted on to three M5 studs as shown in Figure 5–15.
a)
Loosen the ‘Nyloc’ nuts and locate the SMPS on to the studs.
b)
Retighten the three M5 nuts.
The cable supplied as part of the SMPS, should be connected to TB1 on the DELTA transistor module. A 40 way
ribbon cable, supplied as part of the DELTA transistor module, should be connected to PL22 (or PL2 on
MVC3003-4020 and MVC3003-4030) on the SMPS.
