WARNING: Mercury displacement relay must be

mounted vertically. Failure to do this will prevent the
contacts from turning off, which will supply full
voltage to the load. Failure to follow this guideline
could result in damage to equipment, and personal
injury or death.

WARNING: Mercury displacement relay contacts

will switch ac current only. Not for use with dc
current. Failure to follow this guideline could result
in damage to equipment, and personal injury or
death.
