2SPECIFICATIONS (Cont’d)11. CERTIFICATIONS AND COMPLIANCES:ELECTROMAGNETIC COMPATIBILITY:Notes:1. Self-recoverable loss of performance during EMI disturbance at 10 V/m:Process signal may deviate during EMI disturbances.For operation without loss of performance:Unit is mounted in a grounded metal enclosure (Buckeye SM7013-0 orequivalent)I/O and power cables are routed in metal conduit connected to earthground.2. Self-recoverable loss of performance during EMI disturbance at 10 V/rms:Process signal may deviate during EMI disturbances.For operation without loss of performance:Install power line filter, RLC#LFIL0000 or equivalentRefer to the EMC Installation Guidelines section of this bulletin foradditional information.12. WEIGHT: 1.2 lbs. (0.54 Kg)FACTORY CALIBRATIONWhen the unit is shipped from the factory, it is calibrated to read 1,999 with5 amps AC current input.SCALINGThe numerical current value displayed by the Apollo can be scaled down toalmost any numerical value. The coarse scale adjust pot. can be set to divide thenumerical current reading by any division factor between ÷1 and ÷10. The frontpanel fine scale adjust pot. can be used as a fine trim scaling adjustment.DECIMAL POINT SELECTIONThe Apollo 5 amp Current Meter has 3 DIP switches located on the side ofthe unit for the selection of 1 of 3 decimal points for display.EMC INSTALLATION GUIDELINESAlthough this unit is designed with a high degree of immunity toElectroMagnetic Interference (EMI), proper installation and wiring methodsmust be followed to ensure compatibility in each application. The type of theelectrical noise, source or coupling method into the unit may be different forvarious installations. Cable length, routing and shield termination are veryimportant and can mean the difference between a successful or a troublesomeinstallation. Listed below are some EMC guidelines for successful installationin an industrial environment.1. The unit should be mounted in a metal enclosure, that is properly connectedto 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. Theconnection point for the shield depends somewhat upon the application.Listed below are the recommended methods of connecting the shield, in orderof their effectiveness.a. Connect the shield only at the panel where the unit is mounted to earthground (protective earth).b. Connect the shield to earth ground at both ends of the cable, usually whenthe noise source frequency is above 1 MHz.c. Connect the shield to common of the unit and leave the other end of theshield unconnected and insulated from earth ground.3. Never run Signal or Control cables in the same conduit or raceway with ACpower lines, conductors feeding motors, solenoids, SCR controls, andheaters, etc. The cables should be run in metal conduit that is properlygrounded. This is especially useful in applications where cable runs are longand portable two-way radios are used in close proximity or if the installationis near a commercial radio transmitter.4. Signal or Control cables within an enclosure should be routed as far away aspossible from contactors, control relays, transformers, and other noisycomponents.5. In extremely high EMI environments, the use of external EMI suppressiondevices, such as ferrite suppression cores, is effective. Install them on Signaland Control cables as close to the unit as possible. Loop the cable through thecore several times or use multiple cores on each cable for additionalprotection. Install line filters on the power input cable to the unit to suppresspower line interference. Install them near the power entry point of theenclosure. The following EMI suppression devices (or equivalent) arerecommended:Ferrite Suppression Cores for signal and control cables:Fair-Rite # 0443167251 (RLC #FCOR0000)TDK # ZCAT3035-1330ASteward #28B2029-0A0Line Filters for input power cables:Schaffner # FN610-1/07 (RLC #LFIL0000)Schaffner # FN670-1.8/07Corcom #1VB3Corcom #1VR3Note: 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.WIRING CONNECTIONSAs depicted in the drawing showing the rear view of the Apollo 5 amp currentmeter, there is a terminal block where all wiring connections are made.All conductors should meet voltage and current ratings for each terminal.Also cabling should conform to appropriate standards of good installation, localcodes and regulations. It is recommended that power supplied to the unit beprotected by a fuse or circuit breaker.Remove the block for easier access to the terminal screws. To remove theblock, pull from the back of the block until it slides clear of the terminal blockshroud.CAUTION: Disconnect power to all unit terminals before removingterminal blocks. This includes deenergizing the current transformerprimary circuit.POWER WIRINGPrimary AC power is connected to Terminal 1 and 2 (marked A.C. power,located on the left-hand side of the terminal block). For best results, the ACpower should be relatively “clean” and within the specified ±10% variationlimit. Drawing power from heavily loaded circuits that also power loads thatcycle on and off, should be avoided.power mains class Aenclosure class AEN 55011RF interferenceEmissions to EN 50081-2level 3; 10 V/mENV 50204simulation of cordless telephone150 KHz - 80 MHzlevel 3; 10 V/rms 2EN 61000-4-6RF conducted interferencelevel 3; 2 Kv powerlevel 4; 2 Kv I/OEN 61000-4-4fast transients (burst)80 MHz - 1 GHzlevel 3; 10 V/m 1EN 61000-4-3electromagnetic RF fieldslevel 3; 8 Kv airlevel 2; 4 Kv contactEN 61000-4-2electrostatic dischargelevel 4; 30 A/mEN 61000-4-8power frequency magnetic fields200 Hz, 50% duty cycleImmunity to EN 50082-2900 MHz ± 5 MHz
