(Includes Coating
and Terminal Band)
Moving Adjustable Lugs: The coating protects the
resistance wire from shifting and shorting to other
turns during adjustment. However, the following
three steps should always be taken whenever
adjustments are made:
(1) Turn off power to avoid possible operator injury
and damage to the unit. (2) Loosen adjustable lug
until it will slide completely free, without touching the
exposed wire. (3) When adjustment point has been
selected, retighten lug only enough to assure a firm
contact, do not tighten beyond this point. Failure to
follow these three steps in order can result in
damage to the resistor.
