Mark the footprint and anchor holes in preparation for drilling.
WARNING
Risk of injury by restricted access
Before marking the floor with the footprint of the NEBS
2000 frame, ensure there is a minimum safety clearance of
0.9 m (3 feet) in front of or behind a Passport 15000 or
20000. The minimum is required to enable personnel to
safely do various installation, maintenance, or upgrade
tasks on the Passport 15000.
WARNUNG
Verletzungsgefahr
Planen Sie einen Sicherheitsabstand von mindestens 0,9 m
ein, wenn Sie den Umriß des Gestells auf dem Boden
aufzeichnen. Dieser Abstand ist erforderlich, damit vor
und hinter dem Passport 15000 oder 20000 Installations-,
Wartungs- und Aufrüstungsarbeiten gefahrlos möglich
sind.

• Marking the footprint of an NTRU04 frame (also known as the PTE 2000
frame) has no margin of error for adjusting an anchor hole after it is
drilled, or moving a frame to add or replace a component. Each oval
opening in the base of the frame accommodates having a hole to drilled
in the floor (or through a raised tile) at either end of the oval. This
