On DC sections, short circuiting the low-voltage, low-impedance circuits can cause
severe arcing that may result in burns or eye damage. Remove rings, watches, etc. to
avoid shorting DC circuits. Do not install power modules in the shelf until the shelf
and rack are properly mounted and secured.
2.3. ESD
Electro-Static Discharge. Many circuits contain devices which are
susceptible to damage from high impedance voltage sources. To avoid such risks
always follow anti-static procedures.
