4 Installation Procedure
4.1 AC Primary Input
4.1.1 Single Phase, Single 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 39A at 115Vac and 22A at 230Vac, the device 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 22A for 230V input and 39A 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
• Connect as follows: Earth to either earth stud (connect first)
AC1 (Live), AC2 (Neutral)
or AC3 (Live), AC4 (Neutral)
or AC5 (Live), AC6 (Neutral)
• Connection can be made to any of the 3 pairs of input terminals detailed above but to
optimise EMC performance use the nearest safety earth stud and route cables close to the
top of the shelf using the supplied routing clips (see section 4.4 for cable routing details)
• 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.
• 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
• Refer to section 5 entitled “Commissioning the system” before applying AC power.
