Introduction
1. INTRODUCTION
1.1 GENERAL
The Littelfuse Startco Motor Protection System (MPS)
is a modular system with integrated protection, control,
metering, and data-logging functions. The Control Unit
(MPS-CTU) is the core module. It can operate as a stand-
alone unit or with the Operator Interface (MPS-OPI),
RTD Modules (MPS-RTD), and Differential Module
(MPS-DIF). The CTU can be programmed using the OPI
or the communications network. Programmable inputs
and outputs provide a flexible hardware platform and
custom software can be easily loaded from a PC to the
CTU’s flash memory. The MPS block diagram is shown
in Fig. 1.1.

Installation
2. INSTALLATION
2.1 GENERAL
A basic Motor Protection System (MPS) consists of an
MPS-CTU and three customer-supplied current
transformers (CT's) for measuring phase current. For
core-balance earth-fault detection, a 1-A, 5-A, EFCT-1, or
EFCT-2 CT is required. For the optional Ring Terminal
MPS-CTU, the 1-A connection is not available. The
residual phase-CT connection can also be used for earth-
fault detection. Voltage inputs do not require potential
transformers (PT’s) for system voltages up to 600 Vac.
For RTD-temperature measurement, up to three
MPS-RTD modules can be connected to the MPS-CTU.
For differential protection, an MPS-DIF module can be
connected to the MPS-CTU. The MPS-OPI provides an
operator interface for the MPS.
The MPS power-factor-corrected switch-mode power
supply is rated 65 to 265 Vac and 80 to 275 Vdc.
All modules can be mounted in any orientation.
2.2 MPS-CTU CONTROL UNIT
The Control Unit is configured for surface mounting.
Outline and mounting details for the MPS-CTU are
shown in Figs. 2.1 and 2.1.1.
2.3 MPS-OPI OPERATOR INTERFACE
Outline and mounting details for the MPS-OPI are
shown in Fig. 2.2. It is certified for use in Class I, Zone 2
and Class I, Division 2 hazardous locations.
The Operator Interface is configured for panel
mounting or it can be mounted on the MPS-CTU as
shown in Fig. 2.3. The Operator Interface can also be
mounted on the MPS-CTU ring terminal as shown in
Fig. 2.3.1 (surface mount only).
If an optional SE-IP65CVR-M is used, follow the
included installation instructions. See Figs. 2.4 and 2.5.
2.4 MPS-RTD MODULE
Outline and mounting details for the MPS-RTD are
shown in Fig. 2.6. The MPS-RTD will fit inside most
motor RTD-termination junction boxes and it is certified
for use in Class I, Zone 2 and Class I, Division 2
hazardous locations. The MPS-RTD can be surface or
DIN-rail mounted.
2.5 MPS-DIF DIFFERENTIAL MODULE
Outline and mounting details for the MPS-DIF are
shown in Fig 2.7. The MPS-DIF can be surface or DIN-
rail mounted.
2.6 EARTH-FAULT CT’S
Outline and mounting details for the EFCT-1, EFCT-2,
EFCT-26, and SE-CS30 series are shown in Figs. 2.8, 2.9,
2.10, 2.11, and 2.12.
