User Manual – Rev AV AMETEK Programmable Power
MX Series 48
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.
CAUTION: REMOVE ALL INPUT POWER TO THE MX BEFORE REMOVING
THE FRONT PANEL.
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 AMETEK Programmable Power customer service at
service@programmablepower.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.
