Hazardous voltages

Take the following precau ons if you connect hazardous voltages to the WebDAQ 504. A hazardous voltage is a

voltage greater than 42.4 Vpk or 60 VDC to earth ground.

Ensure that hazardous voltage wiring is performed only by qualiﬁed personnel adhering to local electrical

standards.
Do not mix hazardous voltage circuits and human-accessible circuits on the same device.
Make sure that devices and circuits connected to the WebDAQ are properly insulated from human

contact.

Hazardous loca ons: The WebDAQ is not cer ﬁed for use in hazardous loca ons.
