Rack Mounting the HD-220 Appendix
Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply circuitry and
the effect that any possible overloading of circuits might have on overcurrent protection and power
supply wiring. Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other than the direct
connections to the branch circuit (i.e. the use of power strips, etc.).
