4.1.43 Phase Delta Supply
Warning! The MX06 40A Shelf can only be used on a 208Vac phase to phase supply.
In a delta connection system each rectifier input is connected directly across two phases. Due to the maximum voltage rating of the rectifiers being 264Vac this is the maximum
The maximum input current on a 208Vac supply is 9.5A per phase. Choose AC Input cabling rated accordingly. The cabling should be colour coded as required for the country/state concerned.
4.1.4.1Rear Access Connection
To connect the input supply to the MX06 40A Shelf proceed as follows:
•The AC input current to the system should also be limited by an appropriate device in the event of a short circuit as defined in EN60950 to protect the internal wiring of the end use equipment. The device(s) should be rated accordingly.
•Ensure that the AC supply intended for connection is isolated, locked off and under single operator control. Remove the rear cover to leave the view as shown below.
•The main circuit board should have been factory configured for
• Connect as follows: | Safety earth to either earth stud (connect first) |
| Phase 1 to AC1, Phase 2 to AC5, Phase 3 to AC4 |
•Connect the cables terminated with M4 ring crimps using the M4 x 8 screws supplied in the accessory kit.

•Cables should exit through the top left knockout tab. If an alternative knockout is to be used ensure additional insulation is used where cabling passes over secondary parts. Cables should be routed as close to the top of the shelf using the supplied routing clips (see section 4.3 for further routing details.
•Refer to section 5 entitled “Commissioning the system” before applying AC power.
