Safety Precautions
Take the following safety precautions when connecting multiple pieces of information
technology equipment to UPS and PDU units.
WARNING:
HIGH LEAKAGE CURRENT
EARTH CONNECTION ESSENTIAL BEFORE CONNECTING SUPPLY
The summation of the input power for multiple pieces of Information Technology
Equipment through the use of a UPS or PDU can result in high leakage currents.
If the total system leakage current for a system of components exceeds 3.5 mA:
! The use of a detachable input power cord for the UPS or PDU is prohibited.
! The input cord must be securely attached to the UPS or PDU and it should be
connected to the AC Mains by hard wiring or through the use of a
non-residential, industrial style plug that maintains positive earth connection.
! If the total system leakage current through the ground conductor exceeds 5%
of the input current per line, under normal operating conditions, the system
loads should be divided among multiple power connections.
WARNING:
To reduce the risk of personal injury resulting from electric
shock, do not remove the cover from the Power Distribution Unit. There are
no field-serviceable or user-serviceable components inside.
About the Circuit Breakers
The circuit breakers protect the PDU and all devices connected to it from damage
caused by an incoming electrical surge or equipment malfunction.
If power to a device is interrupted, check the circuit breakers and reset, if necessary.
If power is still not restored, contact your authorized Compaq service representative
at 1-800-OK-COMPAQ (1-800-652-6672). For continuous quality improvement,
calls may be recorded or monitored.
