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 II DC power system has been installed into the rack.
