Before Restarting Equipment
Movement of components inside the library can cause serious injury. Before
starting the Tape Library, ensure that the library magazines are closed.
Working on Parts With Line Voltage Present
Work on live parts of the equipment must be authorized by supervision.
When performing such work, observe the following:
• Accident prevention rules
• Perform the following:
– Use only suitable tools and measuring devices in good working condition.
– Check the measuring devices for correct adjustment of measuring ranges.
– Work with one hand only. This can prevent injury to internal organs in case of
electrical shock.
– Avoid contact with conducting floors (especially metal) or equipment parts. If
necessary, cover the working area with suitable protective rubber mats.
Power Cords
To avoid electrical shock, a power cord with a grounded attachment plug has been
provided. Use only properly grounded outlets.
All power cords use an appliance coupler that complies with the International
Electrotechnical Commission (IEC) Standard 320, Sheet C13.
If the power cord that you receive does not match your receptacle, contact your local
dealer.
Power cords used in the United States and Canada are listed by Underwriter’s
Laboratories (UL), are certified by the Canadian Standards Association (CSA), and
comply with the plug standards of the National Electrical Manufacturers Association
(NEMA).
1. Contact with live electrical parts can cause severe or fatal burns and
internal injury as the consequence of electrical shock. After contact with
live parts, persons often cannot break loose from the part by themselves.
2. Components being worked on must only have voltage present when this
is specifically required.
3. Before working on other electrical components, switch OFF power with
the Main switch.
4. Never assume a circuit is without power - always test for power off with
a meter.
