VOLTAGE LEADS
Connect the leads to the three-phase source to be monitored. Input range is
208 to 480VAC.
MANDATORY FUSE PER NEC
Maximum current draw is 60 mA. Fuses provided by factory are rated 1/2A,
600 VAC, 200 KAIC.
PULSE OUTPUT CONNECTOR
Please refer to wiring diagram on page 4.
STATUS LED
The LED blinks green when the product is functioning normally. It will blink
slowly, approximately one second on, then one second off.
If the LED is red and blinking slowly, it may indicate incorrect wiring or a
power factor that is less than 0.5. If the LED is red and blinking fast the CT's
maximum current rating has been exceeded or the pulse rate switches are
incorrectly set.
PULSE RATE SWITCHES
These switches set the pulse output rate. Please refer to Figure 4 for settings.
EXTERNAL CTs (3 phase versions only)
These external CTs are permanently attached and must not be disconnected or
used with other power meters.
