Quick Start Guide
WARNING
Failure to follow safe installation and servicing guidelines could result in
death or serious injury.
•
Ensure the level switch is installed by qualified personnel and in
accordance with applicable code of practice.
•
Use the level switch only as specified in this manual. Failure to do so may
impair the protection provided by the level switch.
Explosions could result in death or serious injury.
•
In explosion-proof/flameproof, increased-safety, and dust ignition-proof
installations, do not remove the housing cover when power is applied to
the level switch.
•
The housing cover must be fully engaged to meet flameproof/explosion-
proof requirements.
Electrical shock could cause death or serious injury.
•
Avoid contact with the leads and terminals. High voltage that may be
present on leads can cause electrical shock.
•
Ensure the power to the level switch is off, and the lines to any other
external power source are disconnected or not powered while wiring the
level switch.
•
Ensure the wiring is suitable for the electrical current and the insulation is
suitable for the voltage, temperature, and environment.
Process leaks could result in death or serious injury.
•
Ensure the level switch is handled carefully. If the process seal is
damaged, gas or dust might escape from the silo (or other vessel)
Any substitution of non-recognized parts may jeopardize safety. Repair
(e.g. substitution of components) may also jeopardize safety and is not
allowed under any circumstances.
•
Unauthorized changes to the product are strictly prohibited as they may
unintentionally and unpredictably alter performance and jeopardize
safety. Unauthorized changes that interfere with the integrity of the
welds or flanges, such as making additional perforations, compromise
product integrity and safety. Equipment ratings and certifications are no
longer valid on any products that have been damaged or modified
without the prior written permission of Emerson. Any continued use of
product that has been damaged or modified without the written
authorization is at the customer's sole risk and expense.
