4.1.2 Single Phase, AB Feed
To connect the input supply to the DC MX06 60A Shelf proceed as follows:
• The AC input current to the system should 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. Maximum input current is 20A per feed at 115Vac and 11A per feed at 230Vac,
the device(s) should be rated accordingly.
• AC Input cabling used should meet all local regulations and be colour coded as required for
country/state concerned. This should be rated at 11A for 230V input and 20A for 115V
input.
• 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 (M4 flange nut
for earth connection) supplied in the accessory kit.
• The cables should exit through one of the top knockout tabs but if an alternative knockout is
to be used ensure additional insulation is used where cabling passes over secondary parts.
Cables should be routed close to the top of the shelf using the supplied routing clips (see
section 4.4 for further details)
• Refer to section 5 entitled “Commissioning the system” before applying AC power.
