VOLTAGE LEADS
A
Connect the leads to the three-phase source to be monitored. Input
range is 208 to 480V.
MANDATORY FUSE PER NEC
B
Maximum current draw is 60 mA. Fuses provided by factory are rated
1/2A., 600V, 200kAIC. For continued protection, replace only with same
type and rating.
N2 BUS
C
Connect to an N2 Trunk. Please refer to wiring diagram on next page.
STATUS LED
D
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.
ADDRESS SELECTION SWITCHES
E
Each device on the N2 BUS must have a unique address. These switches must
be set to assign an individual address before the device is connected to the
N2 BUS. CAUTION: If an address is selected which conflicts with another
device on the N2 BUS, both devices will be unable to communicate.
F
EXTERNAL CTs
These external CTs are permanently attached and must not be
disconnected and/or used with other power meters.
