Unpacking & Installing in Frame
Upon unpacking, check that the unit is not damaged, and that you have the required
number of rectifiers.
The unit flush mounts into a standard 19" mounting frame. The mounting screws
should be #12-24; however, #10-32 may be used with washers. Be sure to mount
the unit in the 19" frame squarely if #10-32 screws are used.
Please note the complete system weight is 13.2kg. (29 lbs.). Ensure the 19"
mounting rails can withstand mounting of the system.
A 5/32" (4mm) wide slotted screwdriver has been provided to allow ease of
accessing some of the smaller recessed DIN style terminal block screws.
Note: Do not fit rectifier modules until the Centurion III DC power system has been installed
into the rack.

AC Cabling
The AC terminals are clearly marked at the rear of the system as shown in Fig 1.0 & 1.1.
The terminals can accept up to 8 AWG/10mm
Once cables are connected, ensure cable clamps are secured. Refer to appendix 5
for AC junction box cover removal (page 24)
The AC earth terminal earths the System chassis. The AC earth is also internally
bonded to the System chassis by earth stud as shown in Fig 1.1. The AC earth
terminal can accept several small cables or up to a single 2 AWG cable.
DC Common (+ve) is connected to the AC earth as shown in Fig 1.1 but can be
removed if output is required to be isolated.
Note: Refer Appendix 3 for AC Input Transient Protection
