Interface Connections
Input Terminal (J1)
Input AC Power is applied to connector J1 using a 3W3 power connector. J1-A1 is Line (L1), J1-A2 is Line 2/
Neutral (L2/N) and J1-A3 is Earth Ground (GND) for safety. See Figure 8 (Pg 4).
A fault clearing device, such as a fuse or circuit breaker, with a maximum 15 A rating at the power supply input
is recommended. It should be sized to handle the start-up inrush of 30 A at 115 VAC and 60 A at 230 VAC.
Customer Interface Connector (J2)
Individual outputs for slots 1 through 3 can be disabled with a logic “0” at pins 1, 2 and 3 of J2. Signal Ground
is available at pin 4. Auxiliary +5 Vcc @ 100 mA is available at pin 5. The AC Power OK at pin 6 is a logic
“1” whenever AC input power is within tolerance. All outputs can be disabled by placing pin 7 at a logic “0” by
connecting to signal ground at pin 4. Pins 8 and 9 are not used. See Figure 9 (Pg 4).
Signal Ground (J2-4)
Signal Ground on J2-4 is an isolated secondary ground reference for all J2 interfacing signals. This is not the
same as Earth Ground on input power connector J1.
Enable/Disable (J2-1 to J2-3)
The Enable/Disable control pins allow outputs to be sequenced either on or off. J2-1 through J2-3 are the con-
trol pins for output cards 1 through 3, respectively. For dual or quad output cards, all outputs in that slot are
enabled or disabled with a single control. The Enable/Disable pins should be pulled low to less than 0.7 V with
respect to Signal Ground to disable the outputs. They will source 4 mA maximum. These pins should be open-
circuited or allowed to exceed 4.5 V when enabled. Do not apply more than 5 V to these inputs at any time.
