Safety
DANGER: Overloading a branch circuit is potentially a fire hazard and a shock hazard under
certain conditions. To avoid these hazards, ensure that your system electrical requirements do not
exceed branch circuit protection requirements. Refer to the information that is provided with your
device or the power rating label for electrical specifications. (D002)
DANGER: If the receptacle has a metal shell, do not touch the shell until you have completed the
voltage and grounding checks. Improper wiring or grounding could place dangerous voltage on the
metal shell. If any of the conditions are not as described, . Ensure the improper voltage or
impedance conditions are corrected before proceeding. (D003)
STOP
DANGER: An electrical outlet that is not correctly wired could place hazardous voltage on the
metal parts of the system or the devices that attach to the system. It is the responsibility of the
customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.
(D004)
DANGER: Heavy equipment — personal injury or equipment damage might result if mishandled.
(D006)
DANGER: Arc Flash/Arc Blast hazard when disconnected with power on. Turn off power before
disconnecting. (L015)
Safety notices
Safety notices may be printed throughout this guide. DANGER notices warn you of conditions or
procedures that can result in death or severe personal injury. CAUTION notices warn you of conditions
or procedures that can cause personal injury that is neither lethal nor extremely hazardous. Attention
notices warn you of conditions or procedures that can cause damage to machines, equipment, or
programs.
World trade safety information
Several countries require the safety information contained in product publications to be presented in their
translation. If this requirement applies to your country, a safety information booklet is included in the

__ 8. 將 Suretest 檢測儀重新插入至 120 V 插座（可能需要延長線）。
__ 9. 重複 Suretest 檢測儀用法說明中指定的測試，尋找 1 歐姆或更小值的指示。
__ 10. 如果接頭有金屬殼體或金屬元件，請從插座中拔出 Suretest 檢測儀。將彈簧夾重新連接至金屬部位，
然後重新插入 Suretest 檢測儀並重複測試。
警告： 如果不移除 Suretest 檢測儀，重新連接彈簧夾時可能會出現電火花。
如需相關資訊，請參閱 Electrical Safety for IBM Service Representatives (S229-8124)，或適用於您所
在地理區域的同等說明文件。
