Installation Sequence - ABB Symphony Harmony Series Instructions Manual

Installation Sequence

This instruction does not discuss the details of grounding sys-
tems. Good grounding practices prevent problems and reduce
system downtime. A complete and properly grounded electrical
system is vital for personnel safety, equipment protections,
and normal process system operation. Digital process control
systems require a single-point grounding system that has two
paths: one path for an alternating current ground (safety
ground) and one path for a direct current ground (system
common).
For detailed information on system grounding, refer to the Site
Planning instruction. Planning

Installation Sequence
Refer to Figure
components of the MPSIII system. Each block of the flow rep-
resents a single task that must be completed before continuing
with the sequence.
Some blocks contain alphanumeric codes. These codes identify
the procedure that describes the steps to complete an indi-
cated task. Complete all of the steps given in a procedure
before continuing to the next procedure.
The procedures have check boxes in the margin by each proce-
dural step. When performing a procedure, check each box as
each step is completed. Some procedures have numbered
warnings and /or cautions under Safety Considerations. A tri-
angle with a warning or caution reference number appears in
the margin by the part of the procedure to which the warning
or caution applies.
By treating each task as a separate entity, the procedures pro-
vide an easy method for finding the information needed to per-
form each task in the installation sequence.
