Electrical installation

Electrical installation drawing
See Electrical Installation Drawing D7000001-928 for further information.
4.3.2
Cable entries
The Rosemount 2460 housing has nine M20 x 1.5 and two M25 x 1.5 entries.
Connections must be made in accordance with local or plant electrical
codes.
Make sure that unused cable entries are properly sealed to prevent moisture
or other contamination from entering the terminal board compartment of
the electronics housing.
NOTICE
Thread sealing (PTFE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seal and to meet the required degree of
ingress protection as well as to enable future removal of the plug/gland.
Use the enclosed metal plugs to seal unused cable entries in order to achieve
required level of ingress protection. The plastic plugs mounted at delivery
are not sufficient as seal.
4.3.3
Power supply
The Rosemount 2460 System Hub accepts supply voltage 100 - 250 Vac
(50/60 Hz) and 24 - 48 Vdc.
Note
The Rosemount 2460 is polarity insensitive for DC voltage input.
4.3.4
Cable selection for power supply
Appropriate cross sectional area of wires must be used in order to prevent a
high voltage drop to the connected device. Recommended cable size is 0.75
2
mm
to 2.1 mm
drop.
4.3.5
Grounding
The housing should always be grounded in accordance with national and
local electrical codes. Failure to do so may impair the protection provided by
the equipment. The most effective grounding method is direct connection
to earth ground with minimal impedance.
There is a grounding screw on the housing which is identified by ground
symbol
18
2
(18 AWG to 14 AWG) in order to minimize the voltage
.
