8.3.3 Torque Requirements
All electrical connections must be tight.
Tables 30 through 31 provide the torque values for the connections in the UPS and batteries. Use
these values unless the equipment is labeled otherwise.
8.4 Detecting Trouble
It is important that the operator check the instrument readings if abnormal equipment
performance is suspected. Any metered value that differs appreciably from normal could mean an
impending malfunction, and should be investigated.
