1. Prepare a small flat tipped screwdriver.
2. Insert the flat tipped screwdriver into the
opening of the ETR cover. Then, lightly turn
the screwdriver to the upside as shown in
the left figure, and the ETR cover will open.
3. There are two kinds of switches for
characteristics setting and for trip indicator
reset. They should be used as follows.
4. For ETR with Display (Option), there is a slide
type switch (Frequency selector switch) as
the left side picture shows. Do not set the
switch at points between the slide. When
operating the switch, use a flat tipped screw-
driver of the following size.
5. When the characteristic is set up, use a
device like a field test device, etc. to make
sure that the required characteristic has
been set.
6. When sealing, seal the ETR cover by using
the sealing hole at the top of the ETR cover.
(Note)
If the switch is set at points between
steps, the characteristics setting
value will be decided at either end
of steps.
