4.1.2 Single Phase, AB Feed

The MX06 40A Shelf can be used on a Single Phase AB Feed system. This means that 2

separate supply’s can be used, each powering 2 of the 4 rectifiers fitted. The system can be

connected to a 230V or 115V supply.

The maximum input current per feed is 7.5A at 230V and 13A at 115V. Choose AC Input cabling

rated accordingly and colour coded as required for country/state concerned.

4.1.2.1 Rear Access Connection

• 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 according to the input current as stated above.

• 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 configured for single phase AB feed use, by

removing LK3 and LK4. This is normally factory configured.

• First the two safety earth connections should be connected to the studs labelled below.

• Feed A should be wired to: AC1 (Live) and AC2 (Neutral)

• Feed B should be wired to: AC5 (Live), AC6 (Neutral)

• 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.
