1. ELECTRICAL CONNECTIONS INSIDE POWER
CORD
1.1 General
Situation
Increased contact resistance at the side of the blue IEC connector of the power cord. The
higher resistance can lead to temperatures on the wire isolation that are beyond the spec-
ification when the lamp is on and c urrent consumption is high.
Cause
• The green wire ferrules prevent that the wires are inserted deep enough into the brass
connector pins. The second screw in the brass pin will only partly clamp the wire.
• The tightening torque of the s crews is important.
Solution
Remove the green ferrules and tighten the screws with the correct torque. See rework
procedure.
Scoop
FLM power cable assemblies without a label that indicates Z3499178-03 (or higher), have
to be reworked.

6. Loosen the 2 screws of each connector pin far enough to clear the hole completely.
Insert the wire back in the brass pin.
Note:Push each wire firmly till the bottom of the pin before tightening the screws!
7. Tighten the 2 screws of each pin by using a torque c ontrolled flat screwdriver 4 mm or
bit driver 4 mm with a torque of 0.9 Nm
Tip: Experience has shown that when using a Philips screwdriver, the head of the screw
is damaged too easily
