Page 8: Wiring Guidelines
SMART 7KT0307 Manual Installation Guidelines 1. This equipment, being built-in-type, normally becomes a part of main control panel and in such case the terminals do not remain accessible to the end user after installation and internal wiring. 2. Conductors must not come in contact with the internal circuitry of the equipment or else it may lead to a safety hazard that may in turn endanger life or cause electrical shock to the operator. 3. Circuit breaker or mains switch must be installed between power source and supply terminals to facilitate power ‘ON’ or ‘OFF’ function. However this switch or breaker must be installed in a convenient position normally accessible to the operator. -

Keys have multiple assignments. Function assignments and key labelling change according to the context of operator input. For reading serial number Touch F1 key for 3 sec. to display 8-digit serial number only for 5 sec. The serial number will be displayed in 2 pages - 4 digits each. Eg.: For serial number 11220002, the display will be: Page 1: 1122 Page 2: 0002 Automatic / manual mode Auto / Manual mode can be set in configuration setting. By default, unit operates in automatic mode. In automatic mode online pages scroll automatically at the rate of 5 seconds per page. In automatic mode when any key is pressed, unit temporarily switches to manual mode and the appropriate page is displayed. If any key is not pressed for 5 sec, unit resumes automatic mode. In manual mode, unit shows the last set page after power on. Password to start configuration When the meter is set to configuration mode by touching keys F1 + F2, the password page will display which shows the password 000.
