• Other factors which may impact wiring access
Recommended:
When using the 9900
Relay Module (3-9900.393),
use ports above, below or across
from Relay Module terminals to
ensure wiring clearance.
Use eye protection and gloves when drilling.
Drill Enclosure conduit ports at a workbench,
not when installed on a pipe, wall or panel.
