Output Terminal Blocks
The BPS30-3 and BPS45-3 have two output terminal blocks, TB1A and TB1B. The BPS30-1 and
BPS45-1 only has one output terminal block, TB1B. The terminal blocks are large enough to
accommodate the recommended wire gauge sizes shown in Table 4-2. 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 BPS BEFORE REMOVING
THE FRONT PANEL.
The correct standard size Allen wrenches for connecting output wiring to TB1A and/or TB1B are
supplied with each BPS in the ship kit. Look for a brown envelope. If the correct tools cannot be found,
contact AMETEK Programmable Power 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.
