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 (RLC #FCOR0000)
TDK # ZCAT3035-1330A
Steward #28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC #LFIL0000)
Schaffner # FN670-1.8/07
Corcom #1VR3
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.
Snubbers:
RLC #SNUB0000
WIRING CONNECTIONS
After the unit has been mechanically mounted, it is ready to be wired. All
conductors should meet voltage and current ratings for each terminal. Also
cabling should conform to appropriate standards of good installation, local
codes and regulations. It is recommended that power supplied to the unit (AC
or DC) be protected by a fuse or circuit breaker.
All wiring connections are made on a fixed terminal block. When wiring the
unit, use the numbers on the label to identify the position number with the
proper function. Strip the wire, leaving approximately 1/4" (6 mm) bare wire
exposed (stranded wires should be tinned with solder). Insert the wire into the
terminal and tighten the screw until the wire is clamped tightly. Each terminal
can accept up to two, 18-gage wires. Wire each terminal block in this manner.
