Pulsafeeder MPC - Manual (Page 23)

8.4.8 Control Input/Output Signal Wiring
Signal wiring is routed through the two unused conduit openings at the
side of the MPC. All input/output signals are connected to the terminal
strips at the edge of the MPC circuit board. Use caution to observe
proper wire location and signal polarity. Always cap or plug unused
openings. Wires should be routed within the enclosure in a manner that
maintains separation between low voltage and extra-low voltage
conductors. Ensure all low voltage wiring is installed as per any
applicable local and national electrical codes and regulations.
Utilize 20 or 22 AWG, 250 V, shielded cable, with a 105
o
C insulation
rating (or better) for all signal input and output wiring. Recommended
strip length is 0.39 inches or 10 mm. Refer to Figure 4 below for signal
connection locations.
U NUSED CONDUIT OPENINGS SHOULD BE PLUGGED AS REQUIRED TO AVOID
INGRESS OF MOISTURE AND CONTAMINANTS INTO THE MPC ENCLOSURE . D O
NOT REMOVE THE FACTORY PROVIDED PLUG FROM OPENINGS THAT ARE NOT
REQUIRED FOR FIELD WIRING .
I T IS RECOMMENDED THAT A WRIST STRAP BE WORN WHEN MAKING
CONNECTIONS TO ANY PRINTED CIRCUIT BOARD .
