Electrical Considerations
Be sure the final installation site has enough AC outlets to support the computer and the
peripherals located close to
it.
Be sure the outlets are grounded and are protected by a circuit
breaker. Be very sure the AC power available meets the electrical specifications. Refer to
Table 2-2 for the exact electrical specifications.
