terminal blocks to their connectors to apply power to the unit.
2.3.3 General Wiring Guidelines
ControlWave PSSMs use compression-type terminals that
accommodate up to #14 AWG wire.
When making a connection, insert the bare end of the wire (approx
¼” max) into the clamp adjacent to the screw and secure the wire.
To prevent shorts, ensure that no bare wire is exposed. If using
standard wire, tin the bare end with solder to prevent flattening and
improve conductivity.
Allow some slack in the wire while making terminal connections.
Slack makes the wires more manageable and helps minimize
mechanical strain on the terminal blocks.
2.3.4 Wiring a Bulk DC Power Supply to the PSSM
Caution
At this time you can also connect power and watchdog wiring.
However; for safety reasons and to prevent accidental damage to the
your bulk DC power supply, do not connect the pluggable terminal
block connectors TB1 and TB2 to the PSSM until after you install, wire,
and configure the CPU module.
Follow the instructions in Section 2.3.3 General Wiring Guidelines when
wiring connections.
Operating
Range
The ControlWave operates from +22.2 Vdc to +30.0 Vdc (with a
n24Vdc input source).
One or Two
Power
Supplies
You can connect one or two bulk DC power supplies (nom24
Vdc) to the PSSM.
The bulk DC supply you connect to terminal
TB2-1
(+VIN) powers the
CPU, communications, and I/O logic circuits. The PSSM converts,
regulates, and filters the power to
+5Vdc, +3.3Vdc, +12Vdc (optional)
and -12Vdc (optional).
+3.3 Vdc. For safety, this circuit has a 3A fuse.
The bulk DC supply (+20.0 to +30Vdc) you connect to terminal
TB2-2
(+VINF) powers the I/O field devices connected to the I/O modules. For
safety, this circuit has a 10A fuse.
Notes:
When you require two bulk power supplies, the first supply (VIN)
must be rated to handle 2 amps.
The fuses for the PSSM
cannot
be replaced in the field.
