Installation Guide
Protection against Electrostatic Discharges
CMOS (Complementary Metal Oxide Semiconductor) technology is highly sensitive to
electrostatic discharges. The use of conductive antistatic flooring is strongly recommended.
Maintenance personnel must wear wrist-straps before handling electronic equipment.
A ground socket is provided in each cabinet.
