3.2.5 Module installation

(1) Installing modules contiguously

In A series PCs, the left side of each I/O module is left open. When
installing an I/O module to the base, do not make any open slots between
any two modules. If there is an open slot on the left side of a module
with 100/200VAC rating, the printed board which contains the hazardous
voltage circuit becomes bare. When it is unavoidable to leave an open slot,
be sure to install the blank module (AG60).
When using the A5

B expansion base with no power supply, attach the

cover packaged with the expansion base to the side of the leftmost
module.

3.2.6 Grounding

There are two kinds of grounding terminals as shown below. Either grounding
terminal must be used grounded.

Be sure to ground the protective grounding for the safety reasons.
Protective grounding

: Maintains the safety of the PC and improves the noise

resistance.

Functional grounding

: Improves the noise resistance.

3.2.7 External wiring

(1) 24VDC external power supply

For special modules that require a 24 V DC I/O module or external power
supply, use a model whose 24 V DC circuit is intensively insulated from
the hazardous voltage circuit.

(2) External

devices

When a device with a hazardous voltage circuit is externally connected to
the PLC, use a model whose circuit section of the interface to the PLC is
intensively insulated from the hazardous voltage circuit.

(3) Insulation

requirements

Voltages are shown in Table 2.
