Confirming Connections and
Finishing Up
After connecting the Multipoint, check to be sure that the Multipoint is
registering both current and voltage and check to be sure the voltage
and current are paired correctly, as described below.
Check the Range Lights (LEDs) for Current
The Multipoint contains range lights for each current connection.
When you connect to power, the range lights indicate whether the
amount of current in the line is between 5% to 70% of the maximum
range (1 to 14 Amps of CT secondary current).
If the current range lights are steady
ON
, you know the CT to
which you’ve connected is presently within the range of the measured
current.
If the current range lights are blinking , the current may be beyond
the range.
If the current range lights are OFF , the current is below 5% of the
range.
WARNING: Unburdened output from a CT is
extremely dangerous. Ensure that the panel is de-
energized or use a shorting block prior to making any
changes. (Note that Reliable Power Meters current
clamps and flexi-CTs have built in burdens; they do
not need to be shorted.)
