LCP100 Local Control Panel
Installation
The Fisher LCP100 Local Control Panel has four (4) mounting holes for on‐site mounting of the device. The LCP100
must be installed so that the wiring connections are on the bottom to prevent accumulation of moisture inside the
box.
When installing the cover tighten the screws evenly in a criss‐cross pattern to a torque of 2.8 N•m (25 lbf•in) to help
ensure the cover is properly installed.

WARNING
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous location, ingress protection,
and temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage
from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or
explosion.
LCP100 protection and wiring methods are defined in table 2‐2. Refer to the LCP100 instruction manual, available
from your Emerson Process Management sales office
or at www.FIELDVUE.com, for installation wiring diagrams.
