Electrical Connections
To install the ZETA6104 so that it is LVD compliant , refer also to the supplemental instruc-
tions in Appendix C. Appendix D provides guidelines on how to install the ZETA6104 in a
manner most likely to minimize the ZETA6104Õs emissions and to maximize the
ZETA6104Õs immunity to externally generated electromagnetic interference.

Pr5V power to the P-CUT pull-up resistor. As an alternative, you can
connect AUX-P to an external supply of up to +24V (but do not use both the on-board +5V
terminal and an external 5-24V supply). If V_I/O is connected to a +5V supply (on-board or
external), AUX-P can be connected to a supply of up to +24V. If V_I/O is connected to an
ex24V supply, AUX-P must also be connected to +24V (or to GND).
Switching levels depend on the voltage applied to V_I/O:
LOW
£
1/3 of V_I/O voltage; HIGH
³
2/3 of V_I/O voltage
NOTE : AUX-P and V_I/O are also used by the HOM, NEG, POS & TRG inputs.
SINKING CURRENT : To make P-CUT (as well as HOM, NEG, POS & TRG) sink current,
connect AUX-P to GND.

Connecting

OUT-P
terminals, see page 14.)
