WIRING OVERVIEW

Electrical connections are made via screw-clamp terminals located on the back of the display. 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 power supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.

When wiring the display, compare the numbers embossed on the back of the display case against those shown in the wiring drawings for

proper wire position.

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).

1. Strip the wire, leaving approximately 0.3 inches (7.5 mm) bare lead exposed (stranded wires should be tinned with solder).

2. Insert the lead under the screw-clamp terminal.

3. Tighten the screw-clamp until the wire is secure.

4. Pull the wire to verify tightness.

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 provide 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 few 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.

•

Mount the meter in a metal enclosure, which is properly connected to protective earth.

•

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.

•

Connect the shield only at the panel where the unit is mounted to earth ground (protective earth).

•

Never run signal or control cables in the same conduit or raceway with AC power lines, heaters, or conductors feeding motors, solenoids

or SCR controls. Run the cables in a 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.

•

Route the signal or control cables within an enclosure as far away as possible from contactors, control relays, transformers and other

noisy components.

•

Keep cable runs as short as possible. Long cable runs are more susceptible to EMI pickup than short cable runs.
