4.1.3 3 Phase Star Supply
The DC MX06 60A Shelf can be used on any of the following supplies: 415V, 400V, 380V or
208V phase to phase.
The maximum input current is 39A on a 208Vac phase to phase supply and 22A on a 380Vac,
400Vac or 415Vac supply. Choose AC Input cabling rated accordingly and colour coded as
required for country/state concerned.
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.
• The main circuit board should have been configured for 3-phase star use by removing
LK2, LK3 and LK6. This is normally factory configured.
• Ensure that the AC supply intended for connection is isolated, locked off and under single
operator control. Remove rear cover to leave view shown below.
• Connect as follows: Earth to either earth stud (marked ‘E’)
Phase 1 to AC1, Phase 2 to AC3 and Phase 3 to AC5
Neutral to AC2, 4 or 6 (neutral required for star configuration).
• 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.
