The Terminals of the NT-Series
Section 1-4
1.4
Mounting the Terminals
The terminals with mounting bolts or lateral mounting slits are mounted from the
rear side. The rear panel mounting is suitable for easy and sealed installation plac-
es where the rear side of the unit is accessible.
The terminal NT15S-SF121B-E is mounted from the front side. This type of in-
stallation is suitable for easy and sealed installation where the rear side of the unit is
not accessible.
The terminals are particularly suitable for mounting in control cabinets with a
mounting plate thickness of approximately 1 to 10 mm.
The front panels permit sealed installation of the units in accordance with the IP65
degree of protection.
The terminals
-
NT4S-SF123B-E
-
NT18S-SF121B-E
-
NT15S-SF121B-E
have a circumferential groove milled into the rear side of the front plate, containing
a rubber sealing.
The terminals
-
NT4S-SF121B-E
-
NT4S-SF122B-E
are equipped with a foam sealing on the rear side of the front plate.
All parts for mounting the units are supplied with the spare parts set.
Special care needs to be taken during installation to maintain this high degree of
protection. The appliance is inserted from the front through the mounting panel
cutout and fastened with the fasteners of the spare parts set. The sealing must be
positioned evenly and the fastening elements tightened uniformly.
When installing the terminal, keep a minimum space of 30 mm around the terminal
for adequate air circulation.
The tightness between the front panel and the mounting surface depends on
the care during installation.
Mounting and connection of the operating terminal to the power supply must be
carried out by authorized and qualified personnel with EMC training.
Operating terminals must be grounded according to regulations.
The application-specific safety- and accident prevention regulations must be ob-
served during the mounting and connection to the power supply, e.g.:
-
EN 60204, Electrical Equipment of Machines
-
EN 292, Safety of Machinery, General Principles for Design
-
DIN 57 100 Part 410, Protection against Electric Shock
Hazardous voltages can exist inside electrical installations that can pose a danger
to humans. Coming in contact with live parts may result in electric shock!
