Shipping
These relays, when not shipped as a part of a
control panel, will be shipped in cartons designed to
protect them against damage. Immediately upon
receipt of the relay, an examination should be made
for any damage sustained during shipment. If injury

or rough handling is evident, a damage claim should
be filed at once with the transportation company
Watts
and the nearest General Electric Sales Office notified
promptly.
Unpacking
Reasonable care should be exercised in unpacking
the relay in order that none of the parts get injured

Storage

1.2
If the relays are not to be installed immediately,
1.7
they should be stored in their original carton in a
I
2.1
place that is free from moisture, dust, and metallic
3. 2
chips. Foreign matter collected on the outside of the
0.7
case may find its way inside when the cover is re­
0.9

moved and cause trouble in the operation of the
relay.

Target and Seal-in Element
2.4
For trip coils operating on currents ranging from
2.9
0.2 up to 2.0 amperes at the minimum control volt­
4 .0
age, set the target and seal-in tap plug in the 0.2-
0.5
ampere tap.
0.7
For trip coils operating on currents ranging from
0.9
2 to 30 amperes at the minimum control voltage,
1.3
place the tap plug in the 2.0-ampere tap.
1.7
2.6
The tap plug is the screw holding the right-hand
3.3
stationary contact of the seal-in element. To change
5.0
the tap setting, first remove the connecting plug.
Then, take a screw from the left-hand stationary
contact and place it in the desired tap. Next remove
the screw from the other tap, and place it in the
left-hand contact. This procedure is necessary to
prevent the right-hand stationary contact from get·
ting out of adjustment. Screws should not be in both
taps at the same time as pickup for d-e will be the
higher tap value and a-c pickup will be greatly in­
creased.
