ATTENTION: To avoid shock hazards, lock out incoming power (refer to Power
Lock-out Procedure on page 47 of Chapter 5 ) before working on the equipment.
Verify with a hot stick or appropriate voltage measuring device that all circuits
are voltage free. Failure to do so may result in severe burns, injury or death.
IMPORTANT The current transformers may be positioned for top or bottom cable exit.
Follow the appropriate procedure described for your starter configuration.
IMPORTANT For ArcShield units, cable size should not exceed 1-500 MCM or 2-350 MCM
