2 Installing Your 1394C Power Connector Key Kit
Installing the Key Kit
Installation of you r 13 9 4 C power connector key kit involves the
replacement of the system module power connector plugs and the
insertion of keys into specified system module terminals.
The replacement plugs are keyed and labeled to prevent an improper
power conne ction. F ollow the procedure starting belo w t o in stal l your
1394C power connec tor key kit.
ATTENTION: The 1394 system module contains
ESD (Elect rostatic Disc h arge) sensitive parts and
!
assemblies. Static control p recau tions are required
when installing, testing, servicing, or repairing this
device. Component damage can result if ESD co ntrol
procedures are not followed. If you are not familiar
with static control procedures, refer to Guarding
Against Electrostatic Damage (publication
8000-4.5.2), or any other appli ca bl e ESD Protection
Handbook.
Removing the Power Connector Plugs
To remove the three power connector plugs:
1. Remove all 24V control power, contactor enable power, and
360/480V AC input power from the system.
ATTENTION: This product contain s stored energy
devices. To av oid hazard of electrica l shock, wait f ive
!
minutes or verif y that all voltage on the system bus
network has been discharged before attempting to
service or repair this unit. Only qualified personnel
familiar with solid state control equipment and safety
procedures in publication NFPA 70E or applicable
local codes should attempt this procedure.

3. Remove the three power connector plugs from the bottom of the
1394C system module.
Replacing the Logic Power Connector Plug
To replace the logic power connector plug:
1. Loosen the screws in the old logic power connector and remove
the wires from each terminal (refer to Figure 2 for connector
location).
2. Insert the wires in to th e replacement connector plug (supplied in
the kit) as sh o w n in the table be low.
Insert the wir es
labeled:
W1 W1
W2 W2
Into the connector
plug terminals labeled:
Tighten to this
torque value:
0.56-0.62 N-m
(5.0-5.6 lb-in.)
3. Gently pull on each wire and make sur e it does not come out of it s
terminal. Re-insert and tighten any loose wires.
