2. Press the two chassis together. If mounting on a DIN rail, slide both chassis onto the DIN rail
first to ensure proper alignment and place clamps/brackets at both ends of assembly on DIN
rail to ensure side connectors between chassis remain fully engaged. (See
Section 2.6 ) .

2.4 General Wiring Guidelines
The RTU’s pluggable terminal blocks use compression-type terminals that accommodate wire
between 24 and 12 AWG depending on the connector or terminal block and the usage. Use 28 to
16 AWG wires on the 20 pin I/O connectors; use 20 to 12 AWG wires on the power connection.
CAUTION
All wires must be rated for a temperature of 90
o
C or higher.
CAUTION
Wires used for power must have a wire gauge between 20 and 12 AWG.
 When making a connection, insert the bare end of the wire (approx. 1/4" max) into the clamp
adjacent to the screw and secure the screw.
 To prevent shorts, ensure that no bare wire is exposed. You can also use crimp bootlace
ferrules (18 to 24 AWG for I/O; 18 to 20 AWG for power).
 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.
