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
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
the Assembling the High Voltage Screw Terminal Backshell section for more information.
