Environmental
Conditions and
Voltage Information
The following table lists important environmental and voltage information.
Wire Sizes and
Insulation
Wire sizes for grounding (earthing), current, voltage, and contact connections
are dictated by the terminal blocks and expected load currents. You can use the
following table as a guide in selecting wire sizes.
Instructions for
Cleaning and
Decontamination
Use a mild soap or detergent solution and a damp cloth to carefully clean the
SEL-700G chassis when necessary. Avoid using abrasive materials, polishing
compounds, and harsh chemical solvents (such as xylene or acetone) on any
surface of the relay.
