DANGER
•Do not remove the service plug without always wearing appropriate Personal
Protective Equipment (PPE) to help protect the dismantler from serious injury or death
by electrical shock.
•
Immediately cover the service plug socket with insulated tape. The high voltage
battery retains high voltage power even when the service plug is removed. To avoid
electric shock, NEVER touch the terminals inside the socket.
To avoid unintended reinstallation and risk of electrical shock and severe personal injury or
death, the dismantler should carry the service plug on his/her person while work is in progress.
