Installation Guidelines

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.
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.
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.
Before disconnecting the secondary of the external current transformer from the equipment, make sure that the current transformer is short circuited to avoid risk of electrical shock and injury.
The equipment shall not be installed in environmental conditions other than those mentioned in this manual.
The equipment does not have a built-in-type fuse. Installation of external fuse of 0.5 A, Class gG type for electrical circuitry is highly recommended.
Remove the scratch-guard from the meter display during commissioning of the panel.

Wiring Guidelines

To prevent the risk of electric shock, power supply to the equipment must be kept OFF while doing the wiring arrangement.
Wiring shall be done strictly according to the terminal layout. Confirm that all connections are correct.
Use lugged terminals.
To reduce electromagnetic interference use of wires with adequate ratings and twists of the same in equal size shall be made with shortest connections.
Layout of connecting cables shall be away from any internal EMI source.
Cable used for connection to power source, must have a cross-section of 1mm2 to 2.5mm2. These wires shall have current carrying capacity of 6A.
Copper cable should be used (Stranded or Single core cable).

Configuration

There are 2 dedicated function keys labelled as F1 and F2. Use these 2 keys to read meter parameters. Use the soft-touch keys to read the parameters. The keys have multiple assignments. Function assignments and key labelling change according to the context of operator input. A short touch on the key triggers the function once. Touching the key for longer switches on the autorepeat function after approximately 1 s. The function of the key is triggered repeatedly while the key is touched. Autorepeat is useful, for example, for fast incrementing of values when parameterizing the device. $SIEMENS-7KT0110 -SMART-7KT-Discrete-Panel-Meter- $14$$
