Wiring
WARNINGS:
• Open SITRANS LVS100/200 only when supply voltage is switched off.
• All field wiring must have insulation suitable for at least 250 V AC.
• A disconnect switch must be in close proximity to the equipment and
within easy reach of the operator.
• Use appropriate conduit or cable glands in hazardous locations.
Unused cable conduit fittings must be locked with a closing element or
plug.
• Observe all pertinent rules and regulations in the country of
installation.
Notes:
European requirements
• When mounting SITRANS LVS100/200 in hazardous areas, make sure the customer
supplied cable glands and/or plugs are certified ATEX 100a flameproof. The
certified temperature range must be at least -40 to +70 °C (-40 to +158 °F). The
minimum ingress protection requirement of IP6x according to European Standard
EN 60529 must be satisfied. Observe special conditions for safe use of the cable
gland described in the gland's approval documentation.
• The requirements of European Standard EN 50281-1-2 regarding dust deposits and
temperature must be followed.

Connection recommendations

• Use a fuse for the signal output (max. 10 A).
• Provide protection for relay contacts to protect the device against spikes if inductive
loads are connected.
Precautions
• Before opening the lid, ensure there are no dust deposits around
SITRANS LVS100/200, and that the atmosphere around the instrument is settled.
• Make sure the main voltage does not exceed the maximum voltage listed on the
product label.
• Ensure that no more than 8 mm of each wire is stripped (to avoid danger of contact
with live parts).
• Ensure the boots for protecting cable terminations are no longer than 8 mm (to avoid
danger of contact with live parts).
