6.5 Electrical connection

WARNING
Ground the case via the process connection against electrostatic charging.
■
Include the case in the equipotential bonding of the application.
For transmitters with flying leads, the screen is connected to the case. The
■
simultaneous connection of case and cable screen to ground is only permit-
ted if ground loop problems between the screen connection (e.g. at the power
supply) and case can be excluded (see EN 60079-14).
Attempting to remove the cable connection will damage the transmitter and
■
void the factory warranty and approval.
The electrical connection to the transmitter should be used as originally
■
supplied. It must not be bypassed or modified (with the exception of the cable
length). Improper assembly or alteration of the electrical connection will invali-
date the explosion protection class for which the transmitter is certified.
Cover flying leads with fine wires by an end splice (cable preparation).
■
For use with electrical conduit the metal protection cap of the electrical connec-
■
tion may be removed. If installed without electrical conduit the protection cap
must not be removed.
Clamp the free cable tail to a suitable certified clamp box or outside the hazar-
■
dous area.
Max. supply voltage: DC 30 V; Max. power dissipation: 1 W
