Cleanness
• Dust concentration ≤ 3 × 10 4 particles/m 3
• No dust on desk within three days
Ventilation
• There is a minimum clearance of 10 cm (3.94 in)
around the inlet and exhaust vents for heat
dissipation of the L1000-A chassis.
• A ventilation system is available at the installation
site.
ESD prevention
• The equipment and rack are well grounded.
• The equipment room is dust-proof. An anti-static
floor is installed and correctly grounded.
• The humidity and temperature are at a compliant
range.
• Wear an ESD wrist strap and uniform when
touching a circuit board.
• Place the removed power modules and interface
modules on an antistatic workbench, with the
face upward, or put it into an antistatic bag.
• Touch only the edges, instead of electronic
components when observing or moving a
removed interface module.
EMI prevention
• Take effective measures to protect the power
system from the power grid system.
• Separate the protection ground of the L1000-A
from the grounding device or lightning protection
grounding device as far as possible.
• Keep the L1000-A far away from radio stations,
radar and high-frequency devices working in
high current.
• Use electromagnetic shielding when necessary.
