8 ACCESSORIES
8.1 Cable gland for terminal box
Device must be installed in accordanc with Article 505
and 506 of the National Electrical Code (ANSI/NFPA 70)
for installation in the United States, or Section 18 of the
Canadian Electrical Code for installations in Canada. Note
that the operating temperature of the cable gland must be
at least 15 K above the maximum ambient temperature.
8.2 External grounding connection for
terminal box
If solenoid coils feature a terminal box, connection terminals are
enclosed for the external grounding connection.
If the potential equalization is not to be connected by a pipeline or
by the use of a plastic fitting, the connection can be made via the
external grounding connection. Its use is therefore optional and
must be assessed by the operator.
The connection capacity of the ring cable lug is 4...6 mm
2
and the
tightening torque is 1.2 Nm. The connection is made as shown in
“Fig. 6” .
