12 Installing the DC Power Supply
Circuit cards contain static-sensitive circuitry and may be damaged or destroyed by
electro-static discharge (ESD). Always wear a static dissipating wrist strap connected to
the unit while handling circuit cards. See Figure 2-14 on page 2-26 . Hold circuit cards by
their edges and avoid touching contact surfaces. Handle with care and do not drop.
Electrical Hazard. If the power supply screws are not fastened to the unit, the power
supply unit will not be grounded and could be subject to hazardous voltages. Do not
proceed further until the screws have been fastened.
