WARNING: Removable Terminal Blocks

When you connect or disconnect the Removable Terminal Block (RTB) with field side power applied, an electrical arc can occur. This could cause an explosion in

hazardous location installations.

Be sure that power is removed or the area is nonhazardous before proceeding.

If you connect or disconnect wiring while the field-side power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.

Be sure that power is removed or the area is nonhazardous before proceeding.

ATTENTION: Make sure the chassis is mounted and all panel fabrication is complete before you remove the protective label. This label protects the power supply

from metal shavings falling inside the power supply and damaging it during operation.
