1.0 InstallIng the Meter

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.

2.0 settIng the JuMpers

INPUT RANGE JUMPER

This jumper is used to select the proper input range. The input range selected
in programming must match the jumper setting. Select a range that is high
enough to accommodate the maximum signal input to avoid overloads. To
access the jumper, remove the side cover of the meter.

Warning: Exposed line voltage exists on the circuit boards.
Remove all power to the meter and load circuits before accessing
inside of the meter.

MOUNTING INSTRUCTIONS

This display is designed to
be wall mounted or
suspended from a ceiling
truss or other suitable
structure capable of
supporting the LDP63200.
Cau tion should be
exercised when hanging
the display to provide for
the safety of personnel. If
hanging the display, run the
suspension cables (or chains)
through the mounting bracket
holes. For wall mounting use
#10-32 size bolts.

3.0 WIrIng the Meter

EMC INSTALLATION GUIDELINES

Although this meter is designed with a high degree of immunity to Electro­Magnetic 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.

c. Connect the shield to common of the meter and leave the other end of the

shield unconnected and insulated from earth ground.

3. Never run Signal or Control cables in the same conduit or raceway with AC

power lines, conductors feeding motors, solenoids, SCR controls, and

heaters, etc. The cables should be ran in metal conduit that is properly

grounded. This is especially useful in applications where cable runs are long

and portable two-way radios are used in close proximity or if the installation

is near a commercial radio transmitter.

4. Signal or Control cables within an enclosure should be routed as far as

possible from contactors, control relays, transformers, and other noisy

components.

5. In extremely high EMI environments, the use of external EMI suppression

devices, such as ferrite suppression cores, is effective. Install them on Signal

and Control cables as close to the unit as possible. Loop the cable through the

core several times or use multiple cores on each cable for additional protection.

Install line filters on the power input cable to the unit to suppress power line

interference. Install them near the power entry point of the enclosure. The

following EMI suppression devices (or equivalent) are recommended:

Ferrite Suppression Cores for signal and control cables:

Fair-Rite # 0443167251
TDK # ZCAT3035-1330A
Steward # 28B2029-0A0

Line Filters for input power cables:

Schaffner # FN2010-1/07
Schaffner # FN670-1.8/07
Corcom # 1 VR3

Note: Reference manufacturer's instructions when installing a line filter.

6. Long cable runs are more susceptible to EMI pickup than short cable runs.

Therefore, keep cable runs as short as possible.

7. Switching of inductive loads produces high EMI. Use of snubbers across

inductive loads suppresses EMI.

WIRING OVERVIEW

Electrical connections are made via pluggable terminal blocks located inside
the meter. All conductors should conform to the meter's voltage and current
ratings. All cabling should conform to appropriate standards of good installation,
local codes and regulations. It is recommended that the power supplied to the
meter (DC or AC) be protected by a fuse or circuit breaker. When wiring the
meter, compare the numbers on the label on the back of the meter case against
those shown in wiring drawings for proper wire position. Strip the wire, leaving
approximately 0.4" (10 mm) bare lead exposed (stranded wires should be tinned
with solder.) Insert the lead under the correct screw clamp terminal and tighten
until the wire is secure. (Pull wire to verify tightness.) Each terminal can accept
up to one #14 AWG (2.55 mm) wire, two #18 AWG (1.02 mm), or four #20
AWG (0.61 mm). Use copper conductors only, with insulation rated at 90°C.

WIRING CONNECTIONS

Internal removable terminal
blocks are used for power and
signal wiring. Access to
terminal blocks is through
conduit fittings. Remove end
plates with ¼" nut driver. For
4" versions, all wiring is on
right side of unit. For 2"
versions, power and relay
wiring is on the right side and
the input, serial, DC out and
user input is on the left side.

Connect drain wire from
shielded cable(s) to screw on
side plate for proper grounding.
