Customize the Wiring
Customize a
Grounded AC System
To customize the wiring of I/O module groups 2-5 to suit your application,
refer General Instructions to Customize Your Wiring (page 3), and follow
the instructions below. Instructions and examples are on facing pages.
Important: If using ungrounded ac power,
go back to the previous section.
ATTENTION: To guard against unexpected machine
operation with possible injury to personnel and/or machinery
damage, do not modify the wiring of system power
distribution (sheet 1 of 9) except as follows:
1.
2.
Deletion of crowbar relays.
Enter your own wiring in the EMERGENCY STOP BY
zone 01-12 for such switches as:
E-Stop pushbuttons
die block
air pressure for C/B and counterbalance
