The installation and servicing of the 1719-TB6S should be carried out by competent and experienced staff. Since the terminal block is primarily going to be used in hazardous locations where there is an ever-present risk of explosions, special precautions to prevent electrostatic discharge must be followed, including cleaning with a moist cloth rather than a dry cloth, wearing a grounding strap, avoiding touching the component boards and the components on the boards, and storing equipment in static-safe packets. To prevent the occurrence of an electrical arc which could cause an explosion in hazardous areas, any I/O module on which the 1719-TB6S is installed should be inserted or removed after the backplane power is turned off.
