• 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. - Page 10 Ac current: 1. Connect CT-53 output terminals to DM-5 current input terminals (A1, A2, A3). Observe the arrow marks for correct connection. 2. Power on DM-5 (unit auto-detects the current transducer connected). 3. Unlock the flexible measuring head according to the followings:...

Page 12: Maintenance
The flexible current transducer and its latching system require no special care. Ensure that no foreign object obstructs the latching mechanism. Clean the CT-53 with a damp cloth and a mild detergent. Do not use abrasives, solvents, or alcohol. If ct-53 does not perform properly, use the following steps to help isolate the problem: • Inspect the coupling system for any damage. - Page 13 Working voltage 600 Vac rms Max allowed input 3600 Aac continuous (45 Hz to 65 Hz) Possible measurable Max.
