T e LECP6** controller s ould be mounted in an IP54 rated metal cabinet
for protection from ESD.
T e metal cabinet s ould be grounded wit a s ort grounding cable.
All s ielded cables must be grounded inside t e cabinet using suitable
metal P-Clip or U-Clip as s own.
T e s ielded cables are:
• 24 VDC Power cable from power supply to LECP6** series controller
• T e Input/output cable from controller to PLC
• Groundin the controller
Please refer to t e “Installation” section
8 CE Directive (continued)
• P-Clip or U-Clip installation
T e function of t e P-clip or U-clip is to provide a 360° metallic contact
and is a convenient met od of ensuring an effective RF ground.
W en dealing wit EMI issues it is important to know t at t e DC
connection does not maintain t e integrity of an AC ig frequency
connection. Hig frequency bonding typically involves using wide flat
cabling to establis an effective system ground. W en applied correctly
t e P-clip or t e U-clip will provide a ig frequency connection.
W en installing a P-clip or U-clip (see figure below) install t e clips as
close to t e cable ends as possible. In order to provide a suitable ground
connection surface, it may be necessary to remove t e paint from t e
panel or t e cabinet, an eart stud or a bus bar are also acceptable.
Remove only t e outer vinyl jacket of t e braided screened cable (t is
allows t e cable braid to connect to t e P-clip or U clip). Take care not to
damage t e braiding. Snap t e P-Clip or t e U-Clip over t e exposed
braiding and adjust for a tig t fit. Secure t e clip to t e designated
ground wit a mac ine screw and lock was er. T e use of a brass or
ot er conductive insert is recommended. Soldering a pigtail to t e cable
s ield is not a suitable met od for providing good RF ground.
