2.6.2 Output Terminal Blocks
The MX45-3Pi and MX45-3 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 2-2. 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.
CAUTION: REMOVE ALL INPUT POWER TO THE MX45 BEFORE
REMOVING THE FRONT PANEL.
The correct standard size Allen wrenches for connecting output wiring to TB1A and/or TB1B are
supplied with each MX45 in the ship kit. Look for a brown envelope. If the correct tools cannot
be found, contact California Instruments customer service at support@calinst.com .
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.
