lug on the power supply at the rear of the SDM-9XXX Series chassis.
For the exact location of the ground lug, see:
“Rear View of the SDM-9120” on page 4-3 or

that the SDM-9XXX Series unit is independently grounded with a wire from Ground
securely attached to the ground lug located at the rear of the SDM-9XXX Series
chassis.

magnetic field or electrostatic charge at any time. Electrostatic
charges can damage system components. Always follow ESD
procedures and use an ESD (Electrostatic Sensitive Devices) wrist
strap when accessing internal components of the unit.
Warning
To avoid electrical shock and damage to the unit, make sure that
the unit is disconnected from its power source before you access
any of its internal components. Use ESD procedure at all times.
