MOUNTING PLATE SELECTION
The 300 A current sensor kit includes 2 power terminal
mounting plates, select the correct plate for the enclosure.
Illustration 1.5
shows the plate for IP21/Type 1 and IP54/
Type 12 enclosures.
Illustration 1.6
shows the plate for IP20/
Chassis enclosures.
To install the new current sensors on the power terminal
mounting plate, use the following steps. Refer to
Illustration 1.6
.
1.
Position the outer 2 current sensors at the top of the
power terminal mounting plate with the base against
the plate.
2.
Invert the middle current sensor so that the base is
at the top.
3.
Align the current sensors so that the cable
connectors face the back of the unit, and the arrows
on the sensors point outward.
4.
Attach the 3 current sensors to the power terminal
mounting plate by fastening 6 thread-forming screws
(T20), 2 per sensor. Torque screws to 2.0 Nm
(17.7 in-lb).
5.
Connect the wire harness by attaching 3 current
sensor cable connectors to the back of the current
sensors, 1 per current sensor.
6.
Attach the 16-pin connector to MK101 on the power
card.
7.
