3 INSTALLATION INSTRUCTIONS
3.8 Testing the Installation
Testing Voltage
Voltage should be tested using an AC Voltmeter to verify that the voltage
across voltage line terminals (L1, L2, and L3 to Neutral) is not in excess of the
maximum rated voltage.
CT Reverse Phase Indicator
Series 1000 and Series 2000 meters have a red reverse phase indicator LED
as described in section 2.3. There must be a load drawing a minimum of
1A connected to the meter in order for the reverse phase LED to function
correctly. If this LED is on (with sufficient load), power down the voltage supply
and verify that CTs are installed correctly.
Load LEDs
The load LEDs are described in section 2.3. These LEDs should be illuminating
at 50% duty cycle, appropriate to the load, when the meter is connected
properly and a constant load is applied. Without a proper load, the load LEDs
could be on or off.
LCD Display
The Series 1000 and 2000 display is described in Section 2.4. From this
description, it is possible to determine if the kWh and/or demand values
displayed on the LCD are consistent with the applied load. A load must be
applied for the kWh value to show significant changes.
3.9 Securing the Enclosure
In accordance with safety requirements, enclosures must be secured. This can be
done once installation is complete by using a key lock. A key lock prevents access
to live parts that pose potential safety risks. To install a key lock, slide it through the
provided holes on the clamp side of the enclosure and fasten it securely. The key
lock is not included with the meter, and must be purchased separately.
