The PROTECTIVE EARTHING CONDUCTORS should be terminated at that point. A recognized or
certified closed loop connector (ring terminal) should be used and secured to the frame with a lock
washer using a bolt or stud. The connector should be properly sized to be suitable for the bolt or
stud, the locking washer, the rating for the conducting wire used, and the considered rating of the
breaker. The intent is to ensure the frame is electrically bonded to the PROTECTIVE EARTHING
CONDUCTORS. The hole that the bolt or stud goes into where the terminal conductor and the lock
washer contact should be free of any non-conductive material to allow for metal to metal contact.
All PROTECTIVE EARTHING CONDUCTORS should terminate at this main protective earthing
terminal or at points marked with . (R010)

General safety
When you service the IBM Cloud Object Storage System
™
5U92 disk enclosure, follow general safety
guidelines.
Use the following general rules to ensure safety to yourself and others.
• Observe good housekeeping in the area where the devices are kept during and after maintenance.
• Follow the guidelines when lifting any heavy object:
1. Ensure that you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the
muscles in your back. Do not attempt to lift any objects that weigh more than 18 kg (40 lb) or objects
that you think are too heavy for you.
• Do not perform any action that causes a hazard or makes the equipment unsafe.
• Before you start the device, ensure that service representatives and other personnel are not in a
hazardous position.
• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing
the unit.
• Keep your tool case away from walk areas so that other people cannot trip over it.
