CAUTION
WHEN ALUMINUM CONDUCTORS ARE USED, THE
APPLICATION OF A SUITABLE JOINT COMPOUND
IS RECOMMENDED TO REDUCE THE POSSIBILITY
OF TERMINAL OVERHEATING. OVERHEATING
CAN CAUSE NUISANCE TRIPPING AND DAMAGE
TO THE CIRCUIT BREAKER.
Table 2 - 2 Rating Plugs
2 - 11. When step - type terminals (TA400K, TA401K,
TA402K or T400K) are used, terminal shields (supplied
with terminals) must be installed on the circuit breaker
(Figure 2
- 4). Warning label supplied with the kit must
be attached to the circuit breaker cover.
WARNING
HAZARDOUS VOLTAGE CONDITIONS CAN CAUSE
DEATH OR SEVERE PERSONAL INJURY. MAIN
-
TAIN ORIGINAL ELECTRICAL CLEARANCE AND
CREEPAGE SPACINGS AT TERMINATIONS.

- 12. Connect the control wires and power wires to their
appropriate locations on the male plug of the terminal
block, see Figure 2
- 5. Control power is necessary if
IMPACC communication is required.

- 14. Plug in the hand held Digitrip OPTIMIZER into the
programming port and set the INCOM address. Then
set the various trip unit current settings using the OPTI
-
MIZER, or when INCOM is available, use the circuit
Connect line and load conductors and accessory
leads.
When a dual conductor terminal (Catalog
No.
TA402K, TA401K, TA400K or T400K is installed on
the circuit breaker and
a single conductor is used,
the conductor should be installed in the terminal
opening nearest to the circuit breaker terminal
mounting conductor.
2-8. Install the supplied neutral current sensor in the
neutral pole of a four
- wire system, see Figure 2 - 6.
2-9. After the circuit breaker is installed, check all
mounting hardware and terminal connecting hardware
for correct torque loading. Torque values for line/load
terminals are given in Table 2
- 1 and on the circuit
breaker nameplate.
2
- 1 0. If required, install line terminal cover on circuit
breaker cover with mounting slots provided.
