3. After the ground rod delay time elapses, the
ground rod (N) inside the isolation cabinet lowers
and discharges the system. Look at the main
system run screen on the control interface to
verify that the system is discharged:
a. Check that the Ground Rod status indicator
shows the ground symbol
Run Menus, page
b. Check that the Voltage Level reading
on the control interface reads 0 kV. See

interface to change to Off mode.
5. Wait one minute before entering the isolation
cabinet. Use a flat blade screwdriver to open the
cabinet.
6. Use the hand-held grounded rod (R) to dissipate
any static discharge in the cabinet before
touching any components. Pick up the grounded
rod (R) and use it to touch all major components
inside the cabinet. For example, use it to touch
the isolation fluid pump (K), the Merkur AA fluid
pump (L), and the isolation valve (G) before
touching any of the system components with
your hands.
