Figure 3-3 Neutral Current Sensor Placement

NOTICE

Do not connect the neutral current sensor secondary

output to ground. Connecting the secondary output

to ground may cause damage to the trip unit.

NOTICE

The polarity of the sensor connections is critical.

Always observe the polarity markings on the instal-

lation drawings. The polarity markings are identified

as white dots on the transformer. To insure correct

ground fault equipment performance, conduct field

test to comply with National Electric Code require-

ments under article 230-95-C. See Section 5.2 for

instructions.

Install accessory(ies), if required, using appropriate

instruction leaflet listed in Section 7.2. Where acces-

sories are not required, install protective barriers sup-

plied with the trip unit in accessory retaining slots of the

trip unit.
