SETTINGS AND PROCEDURES BEFORE
OPERATION
5.4.7 Connecting extension modules
(1) Adding the safety part
• Use an extension module whose input type is the same as that of the main
module. The modules having different input types (input P and N types) cannot
be connected.
• For addition of the safety part, use a safety circuit part extension cable shown on
Section 3.6.
If using another cable, the operation is not guaranteed.
• Connect safety part terminating connector attached to the main module to “OUT”
connector on the extension module on the last stage.
If unconnected, the module does not operate.
(2) Adding the monitor part
Use shielded cable to add the monitor part and ground the shield.
Not doing so may cause a malfunction due to noise.
