2 SMU615 overview
2.1 Overview
SMU615 is a dedicated substation merging unit intended for measuring current
and voltage signals from the instrument transformers and merging them into the
standard digital output format that other devices can further use for various power
system protection application purposes. SMU615 itself includes no protection
functionality but it offers the physical interface into the switchgear primary
equipment, that is, circuit breaker, disconnector and earthing switch. SMU615 is
a member of ABB’s Relion® product family and is characterized by the compactness,
simplicity and withdrawable-unit design.
SMU615 has been designed to unleash the full potential of the IEC 61850 standard
for communication and interoperability in the digital substations. SMU615 supports
process bus according to IEC 61850-9-2 LE with IEEE 1588 v2 time synchronization
and both conventional CT/VT inputs and sensor inputs.

Rated values of the current and voltage inputs are basic setting parameters of the
merging unit. The binary input thresholds are selectable within the range 16…176 V
DC by adjusting the binary input setting parameters.
The connection diagrams of different hardware modules are presented in this
manual.

2.4.1 LEDs
The LHMI includes a dedicated Ready LED indicator and 11 matrix programmable
LEDs on front of the LHMI.
The LEDs can be configured with PCM600 and the operation mode can be selected
via WHMI or PCM600.

2.5 Web HMI
The WHMI allows secure access to the merging unit via a Web browser. When the
Secure Communication parameter in the merging unit is activated, the Web server
is forced to take a secured (HTTPS) connection to WHMI using TLS encryption. The
WHMI is verified with Internet Explorer 8.0, 9.0, 10.0 and 11.0.
WHMI offers several functions.
• Programmable LEDs and event lists
• System supervision
• Parameter settings
• Measurement display
• Disturbance records
• Phasor diagram
• Importing/Exporting parameters
• Report summary

• Locally by connecting the laptop to the merging unit via the front communication
port.
• Remotely over LAN/WAN.
WHMI is enabled by default on the rear port and always enabled (cannot be
disabled) on the front port.
If the WHMI is accessed locally via the front communication port, the following
features are available.
• Setting the merging unit to test mode and testing of outputs
• Trip circuit lockout reset
• Restoring factory settings
2.6 Authorization
Four user categories have been predefined for the WHMI, each with different rights
and default passwords.
The default passwords in the merging unit delivered from the factory can be
changed with Administrator user rights.

2.6.1 Audit trail
The merging unit offers a large set of event-logging functions. Critical system and
merging unit security-related events are logged to a separate nonvolatile audit trail
for the administrator.
Audit trail is a chronological record of system activities that allows the
reconstruction and examination of the sequence of system and security-related
