4 Installation Procedure
4.1 AC Primary Supply
4.1.1 Single Phase
The MX06 40A Shelf can be used on a Single Phase AC supply. The system can be connected
to a 230V or 115V supply.
Maximum input current is 26A at 115Vac and 15A at 230Vac. Choose AC Input cabling rated
accordingly and colour coded as required for country/state concerned.
4.1.1.1 Rear 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.
• 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.
• There are 3 pairs of AC Input connectors: AC1 (Live), AC2 (Neutral)
AC3 (Live), AC4 (Neutral)
AC5 (Live), AC6 (Neutral)
• Connection can be made to any of the 3 pairs but for optimised EMC performance use AC5
(Live), AC6 (Neutral) and the nearest safety earth stud. Access to this should be 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. NB/ Earth connection should be made first.
• Connect the cables terminated with M4 ring crimps using the M4 x 8 screws supplied in the
accessory kit.
• 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.
