Screen and protected earth conductor
Are all the inactive metal parts interconnected by means of large-surface and low-
impedance connections?
Has a proper connection been installed with respect to the ground/protected earth con-
ductor system?
Has the isolation been removed from varnished and anodized surfaces or have these
connections been fitted with special contact washer?
Have the connection been protected from corrosion, e.g. by means of grease?
Have doors been grounded by means of grounding straps connected to the body of the
cubicle?
Cable routing
Cabling divided into groups?
Power cables (230 ... 400V) and signal lines installed in separate channels or
bunches?
Potential compensating
When installing the equipment at separate locations, check the installation of the
potential compensating line.
Cable screen
All covers of plugs are metallic?
All analog and data lines installed screened?
Line screens attached to the screening or the protected earth conductor?
Have the screens been connected by means of large-surface and low-impedance
cable clamps?
