control cabinet is made at the
3-tier terminal block (S3 and S4) for external connections.
NOTES
•
Where several sub-distribution boards must be moni-
tored, additional devices must be connected and wired
with the other devices in a 24V loop.
•
If a 3-phase monitor is to monitor fewer than 3 phases,
then the other inputs on the monitor must be jumpered.
6.6.4 Completing Assembly
•
Refer to the plans and drawings for installation on site
and check all of the circuits that have been made.
•
Check that all connections are tight.
•
Clear away all unused cables, insulation and fixing mate-
rials and all tools and packaging.
•
The revision marking on the final circuits should be done.
