Output Terminal Blocks
The MX30-3, MX30-3Pi, MX45-3 and MX45-3Pi have two output terminal blocks, TB1A and
TB1B. The MX45-1 only has one output terminal block, TB1B. The terminal blocks are large
enough to accommodate the recommended wire gauge sizes shown in Table 3-2. The terminal
blocks are located in the lower right corner on the front of the unit. The front panel needs to be
removed to access these terminal blocks.
The correct standard size Allen wrenches for connecting output wiring to TB1A and/or TB1B are
supplied with each MX in the ship kit. Look for a brown envelope. If the correct tools cannot be
found, contact California Instruments customer service at
Terminal block TB1B always provides the output neutral connection, regardless of the phase
mode (1 or 3 phase output mode).
In single-phase mode, phase A output is provided through terminal 1 of TB1B.
In three-phase mode, phase A, B and C outputs are provided trough terminals 1, 2 and 3 of
TB1A respectively.
