EMC INSTALLATION GUIDELINES
Although this meter is designed with a high degree of immunity to Electro-
Magnetic Interference (EMI), proper installation and wiring methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, source or coupling method into the meter may be different for various
installations. The meter becomes more immune to EMI with fewer I/O
connections. Cable length, routing, and shield termination are very important
and can mean the difference between a successful or troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. The meter should be properly connected to protective earth.
2. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in order
of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.

INSTALLATION
The meter meets NEMA 4X/IP65 requirements when properly installed.
INSTALLATION ENVIRONMENT
The unit should be installed in a location that does not exceed the operating
temperature. Placing the unit near devices that generate excessive heat should
be avoided. The unit should only be cleaned with a soft cloth and neutral soap
product. Do NOT use solvents.
Continuous exposure to direct sunlight may accelerate the aging process of
the front overlay. Do not use tools of any kind (screwdrivers, pens, pencils, etc.)
to operate the keypad of the unit.
MOUNTING INSTRUCTIONS
This display is designed to be
wall mounted or suspended
from a ceiling truss or other
suitable structure capable of
supporting the LDSS.
Caution should be exercised
when hanging the display to
provide for the safety of
personnel. If hanging the
LDSS, run the suspension
cables (or chains) through the
mounting bracket holes. For wall
mounting use #10-32 size bolts.
