• Before each use, inspect the current transducer and its latching system
for any damage. Pay particular attention to the insulation surrounding
the flexible measuring head. Look for cracks or missing portions of the
current transducer housing or output cable insulation. Also look for
loose or weakened components.
• Do not use a current transducer that is cracked, damaged, or has a
defective cable.
• Never use the current transducer on a circuit with voltages higher than
600 V CAT III.
− CAT III equipment is designed to protect against transients in
equipment in fixed equipment installations, such as distribution
panels, feeders and short branch circuits, and lighting systems in
large buildings.
• De-energize the installation on which current will be measured or adopt
safe operating procedures during application and removal of the current
transducer.
• Use extreme caution when working around bare conductors or bus bars.
• Do not use the current transducer to measure bare conductors carrying a
voltage from 30V up to 600V unless you are wearing protective clothing
suitable for high-voltage work. Contact with the conductor could result in
electric shock. Always use appropriate equipment for personal protection.
• Use caution when working with voltages above 60 V dc, 30 V ac rms or
42 V ac peak. Such voltages pose a shock hazard.
• Never apply to current exceeding the measuring range.
• Ensure that no foreign object obstructs the latching mechanism.
• Do not operate the current transducer around explosive gas, vapor, or dust.
• Do not step on or pinch the cord. It may damage the insulation.
• Do not expose the current transducer to direct sunlight, high
temperatures/humidity or dew. It may cause deformation or insulation
degradation.

Warning
to avoid electric shock or personal injury:
• Do not use the current transducer on a circuit with voltages higher than
600 V CAT III.
• De-energize the installation on which current will be measured or adopt
safe operating procedures during application and removal of the current
transducer.
• Disconnect CT-53 from DM-5 by removing CT-53 output terminal plug.
Do not pull CT-53 output cable.
