Use of Aluminum Conductors
The AC terminals in the SOLECTRIA XGI 1000
TM
are dual rated by UL for use with copper or aluminum conductors. When
using aluminum conductors it is important to prepare the conductors properly to prevent oxidation and overheating.
Follow the steps below to prepare and land the conductors.
a)
Strip insulation from the aluminum conductor.
b)
Remove the oxidation from the connection area of the aluminum conductor using a wire brush or other abrasive
means.
c)
Immediately apply a UL listed oxide-inhibiting compound.
d)
Land the conductor on the appropriate terminal and torque to the proper value, see Table 3-5.
NOTICE !
Use of Aluminum Conductors: Special care must be taken when using aluminum conductors. Failure to properly
prepare and maintain aluminum conductors can result in overheating and property damage. Damage caused by
improper use of aluminum conductors will void the warranty.
