FIRMWARE VERSION
The following table provides the most recent firmware and software versions. For best
results, the Configurator version used should match with the firmware version. A complete
list of firmware and software versions is provided on the 70 Series Utilities CD.
NOTE: Host firmware versions 3.0x require 70 Series IEDs with 64 MB SDRAM. Do not
attempt to upgrade older 70 Series IEDs with insufficient memory to v3.0x.

SAFETY SECTION
This Safety Section should be read before commencing any work on the equipment.
Health and safety
The information in the Safety Section of the product documentation is intended to ensure
that products are properly installed and handled in order to maintain them in a safe
condition. It is assumed that everyone who will be associated with the equipment will be
familiar with the contents of the Safety Section.
Explanation of symbols and labels
The meaning of symbols and labels that may be used on the equipment or in the product
documentation is given below.
Installing, Commissioning and Servicing
Equipment connections
Personnel undertaking installation, commissioning or servicing work on this equipment
should be aware of the correct working procedures to ensure safety. The product
documentation should be consulted before installing, commissioning or servicing the
equipment.
Terminals exposed during installation, commissioning and maintenance may present a
hazardous voltage unless the equipment is electrically isolated.
If there is unlocked access to the equipment, care should be taken by all personnel to
avoid electric shock or energy hazards.
ML0021 August 15, 2018 xiv Copyright 2018 Bitronics, LLC
Voltage and current connections should be made using insulated crimp terminations to
ensure that terminal block insulation requirements are maintained for safety. To ensure
that wires are correctly terminated, the correct crimp terminal and tool for the wire size
should be used.
Before energizing the equipment, it must be grounded (earthed) using the protective
ground (earth) terminal, or the appropriate termination of the supply plug in the case of
plug connected equipment. Omitting or disconnecting the equipment ground (earth) may
cause a safety hazard.
The recommended minimum ground (earth) wire size is 2.5 mm2 (#12 AWG), unless
otherwise stated in the technical data section of the product documentation.
Before energizing the equipment, the following should be checked:
1. Voltage rating and polarity
2. CT circuit rating and integrity of connections
3. Protective fuse rating
4. Integrity of ground (earth) connection (where applicable)
5. Equipment operating conditions
The equipment should be operated within the specified electrical and environmental limits.
Current transformer circuits
Do not open the secondary circuit of a live CT since the high voltage produced may be
lethal to personnel and could damage insulation.
Insulation and dielectric strength testing
Insulation testing may leave capacitors charged up to a hazardous voltage. At the end of
each part of the test, the voltage should be gradually reduced to zero, to discharge
capacitors, before the test leads are disconnected.
Removal and insertion of modules
All M87x active circuitry is located on removable modules. Unless a Module is specifically
intended for Hot Swap (see documentation), it must not be inserted into or withdrawn from
equipment while it is energized, since this may result in damage. Hot Swap modules may
be installed and removed under power. Refer to the appropriate section or manual to
determine if the particular module is Hot Swap compatible. For all other modules,
remove all power from the unit before installing or removing any module.
All Hazardous Voltages MUST be removed from the M87x before removing or
ML0021 August 15, 2018 xv Copyright 2018 Bitronics, LLC
installing the Power Supply Module (Vxx) or the Signal Input Module (S1x).
All connections to a module must be removed before removing the module. Do not
attempt to install a module with signals connected.
Fiber optic communication
Where fiber optic communication devices are fitted, these should not be viewed directly.
Optical power meters should be used to determine the operation or signal level of the
device.
WARNING: EMISSIONS – CLASS A DEVICE (EN55011)
This is a Class A industrial device. Operation of this device in a residential area may
cause harmful interference, which may require the user to take adequate measures.
DECOMMISSIONING AND DISPOSAL
1. Decommissioning
The auxiliary supply circuit in the equipment may include capacitors across the
supply or to ground (earth). To avoid electric shock or energy hazards, after
completely isolating the supplies to the relay (both poles of any dc supply), the
capacitors should be safely discharged via the external terminals before
decommissioning.
2. Disposal
It is recommended that incineration and disposal to watercourses is avoided. The
product should be disposed of in a safe manner. Any products containing batteries
should have them removed before disposal, taking precautions to avoid short
circuits. Particular regulations within the country of operation may apply to the
disposal of lithium batteries.

1.0 DESCRIPTION
1.1 Introduction
The M87x family of monitoring and recording IEDs with SubCycleTM technology is a major
breakthrough in power measurement technology. The M87x IEDs were designed to
expand the limits of range, speed, and accuracy of measurement, speed of
communications, and modularity. It combines a modular-by-board chassis featuring a
CompactPCITM card cage, with a dual processor measurement system featuring a 32-bit
floating point Digital Signal Processor (DSP) and a 486-based host processor.
1.2 Features
Extensive measurement set including two sets of voltages and currents with
corresponding power and energy on some models
Simultaneous support of multiple protocols over multiple physical links
Two completely independent Disturbance Recorders
Two separate Waveform Recorders
Trend Recorder
Sequence of Event log
Voltage Fluctuation Table to use for sag and swell reporting
Two options for analog inputs, 8 voltages with 4 currents and 2 auxiliary voltages or 8
voltages with 6 currents
128 samples per cycle, 16-bit sampling.
32-bit floating point DSP, capable of 180 MFLOPS (Million Floating Point Operations
Per Second). A 128-point complex Fast Fourier Transform (FFT) is performed in less
than 50 microseconds.
486-class Host processor.
Watchdog timer maximizes system reliability.
4 Configurable serial ports - Three RS232/RS485 ports/one DB9M Service RS232 port
Fully compatible CompactPCITM backplane and system bus.
Rugged all-aluminum housing.
Choice of standard chassis (C07A5) with 3 option cPCI expansion bays, intermediate
chassis (C10A7) with 5 option bays or extended model (C12A8) with 6 option bays.
Option modules include digital I/O (P30A, P31 and P33), Ethernet (E1/E3, P10, P11,
P12), and transducer input (P40)
Split-core CT options (3 or 4 for M871, 6 for M872)
Optional detached display, D650 (replaced obsolete display M870D)
