1.1 CPU Mount Base
The CPU mount base is classified as one o
f
the following three types:
• 2-slot mount base (type: HSC-1020)
• 4-slot mount base (type: HSC-1040)
• 8-slot mount base (type: HSC-1080)
For the 8-slot mount base, for example, up
to eight modules can be mounted.

PS slot: Slot into which the CPU power
supply (LVQ000) is inserted.
CPU slot: Slot into which a CPU module
(LQP000, LQP010) is inserted.
Slot 0 to slot 7: Slots into which CPU
optional modules or I/O
modules are inserted.
CAUTION
 Be sure to insert J.NET modules sequentially into the slots, starting from the
leftmost slot, without creating any empty slots in between.
 When only one J.NET module is inserted, set it as the main module.

1 BEFORE USE
1-3
Note the following when mounting optional modules:
 As shown in the figure below, mount an optional module upright on the CPU extension mount
base. (As shown in the bad example below, mounting the optional module aslant on the mount
base may cause a connector pin to bend. If the pin is bent, the optional module may
malfunction.)
Bad example Good example
CAUTION
If the mount base is installed overhead because of the cabinet structure, you may
use a stepladder or something similar to install the optional module. However,
never install it aslant.

REQUIREMENT
 In frame ground (FG) cabling, connect the FG terminal of each module with
external terminals to the cubicle ground terminal of the mount base. The
grounding cable wired from the mount base’s ground terminal must be
grounded by Class-D grounding. It must be up to 2 meters long.
 Use a ground wire whose cross-sectional area is 2 mm2or greater.
* Class D grounding is defined in the Technical Standard for Electrical Facilities of Japan. This
standard states that the grounding resistance must be 100 ohms for equipment operating on 300
VAC or less, and 500 ohms or less for devices that shut down automatically within 0.5 seconds
when shorting occurs in low tension lines.
