Table 3.2 Terminal Block Electrical Specifications
To make the terminal-block connections:
1. Loosen the screws from the cable-entry/conduit box cover and pull the cables through the knockout leaving
some slack for connection.
NOTE: We recommend using the knockouts to install input and output wiring in separate conduit. You must use a
suitable cable gland or risk electric shock.
2. Referring to the appropriate terminal-block connection instructions, connect the cables to the corresponding
input/output terminals and use a torque wrench to turn the screw clockwise until tightened as specified in Table
3.2 above. Refer Connecting to Terminal Blocks on 5 kVA, 8 kVA, and 10 kVA models below.
3. Re-install the cable-entry/conduit-box cover and tighten the screws.

These models offer a single type of I/O connection, 1-in 1-out common source. Figure 3.4 below, shows the terminal block.
Refer to the details in Terminal Block Connections on the previous page, when making the connections.
