Safety Guidelines for Hazardous Voltages
If
hazardous voltages
are connected to the module, take the following
precautions. A hazardous voltage is a voltage greater than 42.4 V
pk
or
60 VDC to earth ground.
Caution
Ensure that hazardous voltage wiring is performed only by qualified personnel
adhering to local electrical standards.
Caution
Do
not
mix hazardous voltage circuits and human-accessible circuits on the same
module.
Caution
Make sure that devices and circuits connected to the module are properly
insulated from human contact.
Caution
When module terminals are live with hazardous voltages, make sure that the
terminals are
not
accessible by using the high voltage screw terminal enclosure. Refer to
Assembling the High Voltage Screw Terminal Backshell
section for more information.
