Construction
Main Housing
The main housing consists of a case, a rear panel dependent upon the ordering num-
ber of the device, and a front cover without operating and display elements. Mats with
guide rails are mounted on the top and the bottom of the interior of the case. The guide
rails enable the printed circuit boards to be properly installed. The guide rails also sup-
port the boards while they are in-place. Each guide rail has a visible number, from 1
to 42, indicating the installation locations of the printed circuit boards. The printed cir-
cuit boards are inter-connected with ribbon cables and plug connectors. The terminals
for connecting the 7SJ63 to external equipment are on the rear panel, which is bolted
to the housing.
Nameplate stickers, which show important information such as the power supply rat-
ing, nominal current rating, and ordering number (MLFB), are located on the top of the
main housing and the interior of the device front cover.
Angle strips attached to the top and the bottom of the main housing are provided for
mounting purposes. Three holes are in each angle strip for a device with housing size

Operator Panel
The operator panel consists of a front cover and a housing. The cover contains a flat
keypad with the operating and display elements necessary to operate the 7SJ63. The
cable for interfacing with the main housing is connected to the keypad via plug con-
nectors.
Slotted holes behind the four caps at the corners of the front cover are provided for
mounting the operator panel to a plate with appropriate screws.
The significance of the operating and display elements on the cover is given in the in-
formation related to Figure 2-1.
