Installing or removing modules or wiring with power applied to the
system or field wiring can cause an electrical arc. This can result in
unexpected and potentially dangerous action by field devices. Arcing is
an explosion risk in hazardous locations. Be sure that the area is non-
hazardous or remove power appropriately before installing or removing
modules or wiring.
Potentially dangerous voltages are present on a module's terminals,
even when system power is turned off. Field power must be turned off
when installing or removing a terminal block assembly.
Personnel, who install, operate and maintain automation systems that
contain these products must be trained and qualified to perform those
functions.
Overloading power modules or Network adapter can result into electric
arc and damage to modules.
Check the rated voltage and terminal array before wiring.
Ensure that specified environmental conditions are not exceeded.
Avoid placing the module in direct sunlight.
Review module specifications carefully, and ensure that input and
output connections are made in accordance with the specifications.
Use specified cables for wiring.
Field power isolators must be used according to the requirements of
the 5VDC/24VDC/48VDC or AC voltage modules used in the system.
If system power consumption exceeds the power limits, use system
power expansion modules.
Power supplies for system power and field power must be supplied
from separate sources.
