American Power Conversion 2200 manual Safety

2. Safety

CAUTION!

■To reduce the risk of electric shock in conditions where load equipment grounding cannot be verified, disconnect the unit from the AC power outlet before installing a computer interface or accessory slot signal cable. Reconnect the power cord only after all signaling connections are made.

■Connect the unit to a two-pole, three-wire grounding AC power outlet. The receptacle must be connected to appropriate branch protection (fuse or circuit breaker). Connection to any other type of receptacle may result in a shock hazard and violate local electrical codes.

■The unit has an internal energy source (the battery). The output may be energized when the unit is not connected to an AC power outlet.

■To deenergize the outputs of the unit, first press the Off button for more than one second to switch the unit off. Next disconnect the unit from the AC power outlet. To deenergize the unit completely, disconnect the battery. See section 10.

■This unit’s protective Earth conductor carries the leakage current from the load devices (com- puter equipment). This unit generates approximately 1.5 mA of leakage current. To ensure a safe limit of 3.5 mA, limit the total leakage current of the load devices to 2 mA.

■Use of this equipment in life support applications where failure of this equipment can reason- ably be expected to cause the failure of the life support equipment or to significantly effect its safety or effectiveness is not recommended.
