SAFETY DIRECTIVES AND STANDARDS
Conditions of Use
To comply with the stated directives and standards, you must meet the
following conditions of use:
• Before making any other connection to this device, connect the auxiliary
Protective Earth ground terminal to a local earth ground with a copper wire
thatissized accordingtotheapplicablerequirements(see“Specifications”
on page 3-1).
• Install and operate this device in an overvoltage category II installation
only.
• Install and operate this device only in a pollution degree 2 or better
