Instructions for inserting Chill Block assembly

1.

Ensure all power is disconnected.

2.

Slowly push the chill block assembly into the PowerCage. Ensure that the
stabs are aligned with their connectors at the back of the PowerCage. This
is difficult to see. When the stabs are properly aligned and in place, the
chill block assembly will be seated squarely and the support bracket should
be resting on the PowerCage base when positioned correctly.

ATTENTION: The chill block assembly is heavy and it is recommended
that two people pull the assembly out to avoid damage.

ATTENTION: Remove plastic film from chill block before installation. Failure to
remove the film will result in device failure.

TIP

If the stabs are not seated properly in the brackets, damage can occur.
Measure the snubber resistance and sharing resistance to ensure that
contact has been made. If rear access to the drive is available, remove
backplates and visually verify.
