•
SNAP-PAC-S1 controllers with serial numbers lower than 500000 have an 8–24 VDC input rating.
Using
an input voltage above this range will cause damage that is not covered by the warranty.
The SNAP-PAC-S1 serial number appears on the sticker on the side of the unit. The input voltage rating is
shown on the top cover of the controller.
INSTALLING HARDWARE
NOTE: If you are using redundant controllers, see steps in the
SNAP PAC System Redundancy User’s Guide
1.
Install Opto 22 I/O units according to instructions in the brain’s user’s guide.

2.
Choose a convenient mounting location for the SNAP PAC S-series controller and either panel-mount or
DIN-rail mount it according to the diagrams on
.
3.
Confirm that the power supply to be used with the controller is turned off or unplugged, and discharge
any residual charge that may remain in the power supply.
4.
With the power supply off or unplugged, connect the power supply to the controller.
CAUTION: Reversing wire polarity may cause damage to your controller. This damage is not covered by Opto 22’s
warranty. If you are not certain about the polarity of the wires on your power supply, check with a meter.
a.
With the power supply off or unplugged, connect the
+
(positive) lead from the power supply
(normally red) to the
+
(positive) terminal on the face of the controller.
b.
Connect the COM wire from the power supply (normally black) to the
–
(negative) terminal on the
face of the controller.
c.
Connect a lead from a known chassis ground to the
(ground) terminal on the face of the
controller.
IMPORTANT:
Do not turn on power to the controller.
5.
Using Category 5 or superior solid unshielded twisted-pair cable, connect the SNAP PAC S-series
controller using Ethernet port ENET 1 in one of the following ways:
–
(Recommended for initial configuration) Connect to a PC directly, using an Ethernet crossover cable.
NOTE: If you use a crossover cable, make sure to assign a fixed IP address to the network card (NIC) on your
computer. Otherwise, if your network card is configured to get its IP address via DHCP, when you unplug the
computer from the network, the computer will no longer have an IP address. When you are finished using the
crossover cable, you can change the setting back to DHCP.
NOTE: Wired+Wireless models must be initially configured using a wired interface. After you’ve assigned IP
addresses and configured wireless communication parameters, you can communicate with the PAC on the
wireless LAN.
–
Connect to a standard 10BASE-T or 100BASE-TX Ethernet network that has a PC on the same subnet
as the controller and does NOT have a Dynamic Host Configuration Protocol (DHCP) server.
