Fig. 5 Drilling Plan “B” - Front View
NOTE:
On some versions of the K-1600 / 2000
Breakers, the hole for the PT and / or HV
Wires can not be drilled where indicated in
Drilling Plan “B”. If this is the case with
the Breaker Being Retrofitted, follow the
instructions in Step 3-D.
D.
For Use on Some Versions:
Working from the
rear of the Breaker and using a .500" drill bit,
drill a hole in the right Breaker Angle, directly
below the top Breaker Cross Rail (similar to the
hole for the Sensor Harness drilled in Step
3-B). This hole will be used later in the Retrofit
Process when connecting the PT and / or HV
Wires.
STEP 4:
PREPARING THE DTA ASSEMBLY
FOR INSTALLATION
Fig. 6 Overview - DTA Assembly
NOTE:
If an existing Breaker component does not
allow the DTA to be mounted on the right
side of the Breaker (when viewed from the
rear of the Breaker), a left hand DTA
mounting kit is available. For details and
to acquire the necessary parts, contact
