DANGER
Risk of electrocution
The inverter contains high voltage lines. Do not open the front

lines inside the inverter are active, and you risk being
electrocuted.

Damage to backplane connector pins
Use light thumb pressure to align the card with the connectors.
Next, use the levers to seat the card into the connectors. Failure
to align the card first may result in bending of the backplane
connector pins.
CAUTION
Loss of service
Subscriber service will be lost if you accidentally remove a card
from the active unit of the peripheral module (PM). Before
continuing, confirm that you are removing the card from the
inactive unit of the PM.
