Only qualified personnel are to operate the device. Such personnel must be thoroughly familiar with all safety
cautions and warnings in this manual and with applicable country, regional, utility, and plant safety regulations.
Hazardous voltages can exist in the power supply and at the device connection to current transformers, voltage
transformers, control, and test circuit terminals. Make sure all sources of such voltages are isolated prior to
attempting work on the device.
Hazardous voltages can exist when opening the secondary circuits of live current transformers. Make sure that
current transformer secondary circuits are shorted out before making or removing any connection to the current
transformer (CT) input terminals of the device.
For tests with secondary test equipment, ensure that no other sources of voltages or currents are connected to such
equipment and that trip and close commands to the circuit breakers or other switching apparatus are isolated,
unless this is required by the test procedure and is specified by appropriate utility/plant procedure.
When the device is used to control primary equipment, such as circuit breakers, isolators, and other switching
apparatus, all control circuits from the device to the primary equipment must be isolated while personnel are working
on or around this primary equipment to prevent any inadvertent command from this device.
Use an external disconnect to isolate the mains voltage supply.
Personal safety can be affected if the product is physically modified by the end user. Modifications to the product
outside of recommended wiring configuration, hardware, or programming boundaries is not recommended end-use
practice. Product disassembly and repairs are not permitted. All service needs to be conducted by the factory.

Product descript ion
This chapter outlines the product, order codes, and specifications.
2.1 Product description
The M60 Motor Protection System is part of the Universal Relay (UR) series of products. It is a microprocessor-based relay
for the protection and management of medium and large motors.
Overvoltage and undervoltage protection, thermal overload, fault diagnostics, and remote terminal unit (RTU) functions are
provided. The M60 provides phase, neutral, ground and negative sequence, instantaneous and time overcurrent
protection. The time overcurrent function provides multiple curve shapes or FlexCurve™ for optimum co-ordination.
The relay also features an enhanced thermal model with custom curves, current unbalance biasing, and running and
stopped exponential cooling curves. An optional resistance temperature detector (RTD) module allows for the thermal
model RTD bias function. Motor start and supervision functions include starts per hour, time between starts, restart time,
acceleration time, emergency restart, and start inhibit. Sensitive directional power, mechanical jam, and current
unbalance elements are included as standard functions. Additional functions that are not part of the standard M60
element set can be easily configured and implemented using the FlexElement™ and FlexLogic™ functionality.
Voltage, current, and power metering are built into the relay as standard features. Current parameters are available as
total waveform root mean square (RMS) magnitude, or as fundamental frequency only RMS magnitude and angle (phasor).
Diagnostic features include an event recorder capable of storing 1024 time-tagged events, oscillography capable of
storing up to 64 records with programmable trigger, content, and sampling rate, and data logger acquisition of up to 16
channels, with programmable content and sampling rate. The internal clock used for time-tagging can be synchronized
with an IRIG-B signal, using the Simple Network Time Protocol (SNTP) over the Ethernet port, or using the Precision Time
Protocol (PTP). This precise time stamping allows the sequence of events to be determined throughout the system. Events
can also be programmed (via FlexLogic equations) to trigger oscillography data capture that can be set to record the
measured parameters before and after the event for viewing on a computer. These tools significantly reduce
troubleshooting time and simplify report generation in the event of a system fault.
Several options are available for communication. An RS232 port (USB port with the graphical front panel) can be used to
connect to a computer for the programming of settings and the monitoring of actual values. The rear RS485 port allows
independent access by operating and engineering staff. It can be connected to system computers with baud rates up to
115.2 kbps. All serial ports use the Modbus RTU protocol. The IEC 60870-5-103 protocol is supported on the RS485
interface. IEC 60870-5-103, DNP, and Modbus cannot be enabled simultaneously on this interface. Also only one of the
DNP, IEC 60870-5-103, and IEC 60870-5-104 protocols can be enabled at any time on the relay. When the IEC 60870-5-103
protocol is chosen, the RS485 port has a fixed even parity and the baud rate can be either 9.6 kbps or 19.2 kbps. The
100Base-FX or 100Base-TX Ethernet interface provides fast, reliable communications in noisy environments. The Ethernet

port supports IEC 61850, Modbus/TCP, TFTP, and PTP (according to IEEE Std. 1588-2008 or IEC 61588), and it allows access
to the relay via any standard web browser (M60 web pages). The IEC 60870-5-104 protocol is supported on the Ethernet
port. The Ethernet port also supports the Parallel Redundancy Protocol (PRP) of IEC 62439-3 (clause 4, 2012) when
purchased as an option.
Secure Routable GOOSE (R-GOOSE) is supported with software options.
The EnerVista UR Setup software suite contains an automatic configurator for motor starting settings. The configurator
automatically populates settings and operands for input relays, output relays, trip bus, AC inputs, and signal sources based
on user requirements and the relay features.
Settings and actual values can be accessed from the front panel or EnerVista software.
The M60 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are
upgradable.

• CyberSentry security — Advanced security available using a software option. When purchased, the option is
automatically enabled, and the default Password security and EnerVista security are disabled.
2.2.0.1 EnerVista security
The EnerVista security management system is a role-based access control (RBAC) system that allows an administrator to
manage the privileges of multiple users. This allows for access control of UR devices by multiple personnel within a
substation and conforms to the principles of RBAC as defined in ANSI INCITS 359-2004. The EnerVista security
management system is disabled by default to allow the administrator direct access to the EnerVista software after
installation. It is recommended that security be enabled before placing the device in service.
Basic password or enhanced CyberSentry security applies, depending on purchase.
2.2.0.2 Password security
Password security is a basic security feature present by default.
Two levels of password security are provided: command and setting. Use of a password for each level controls whether
users can enter commands and/or change settings.
The M60 supports password entry from a local or remote connection. Local access is defined as any access to settings or
commands via the front panel interface. This includes both keypad entry and the through the front panel RS232 port.
Remote access is defined as any access to settings or commands via any rear communications port. This includes both
Ethernet and RS485 connections. Any changes to the local or remote passwords enables this functionality.
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the M60, the remote password must be used. If the
connection is to the RS232 port of the front panel, the local password applies.
Password access events are logged in the Event Recorder.
2.2.0.3 CyberSentry security
CyberSentry embedded security is available using software options that provide advanced security services. When an
option is purchased, the basic password security is disabled automatically.
CyberSentry provides security through the following features:
• An Authentication, Authorization, Accounting (AAA) Remote Authentication Dial-In User Service (RADIUS) client that is
centrally managed, enables user attribution, provides accounting of all user activities, and uses secure standards-
based strong cryptography for authentication and credential protection
• A Role-Based Access Control (RBAC) system that provides a permission model that allows access to UR device
operations and configurations based on specific roles and individual user accounts configured on the AAA server (that
is, Administrator, Supervisor, Engineer, Operator, Observer roles)
• Security event reporting through the Syslog protocol for supporting Security Information Event Management (SIEM)
systems for centralized cybersecurity monitoring
• Strong encryption of all access and configuration network messages between the EnerVista software and UR devices
using the Secure Shell (SSH) protocol, the Advanced Encryption Standard (AES), and 128-bit keys in Galois Counter
Mode (GCM) as specified in the U.S. National Security Agency Suite B extension for SSH and approved by the National
Institute of Standards and Technology (NIST) FIPS-140-2 standards for cryptographic systems
CyberSentry user roles
CyberSentry user roles (Administrator, Engineer, Operator, Supervisor, Observer) limit the levels of access to various UR
device functions. This means that the EnerVista software allows for access to functionality based on the user’s logged in
role.
Example: Administrative functions can be segmented away from common operator functions, or engineering type access,
all of which are defined by separate roles (see figure) so that access of UR devices by multiple personnel within a
substation is allowed.
One role of one type is allowed to be logged in at a time. For example, one Operator can be logged in but not a second
Operator at the same time. This prevents subsets of settings from being changed at the same time.
