GraceSense HSM User manual
QUICK START GUIDE
Installation of the GraceSense™ Hot Spot Monitor (HSM) has been engineered to be simple and
straightforward. This document will describe in detail the 3 steps needed for installation.
No specialized knowledge of fiber optics is necessary. A basic understanding of electrical equipment
topology and mounting methods is required.
REQUIRED FOR INSTALLATION
Tools for Fiber Mounting:
• Adjustable Wrench
• 1.5 mm Allen Key
• Guillotine Cutter
Components for Hardware
Installation:
• 35 mm DIN rail (6”-8”) and
mounting hardware
• CAT5 Ethernet cable
(if connecting to SCADA
or computer.)
Power Supply Requirements:
• Voltage: 12-24 VDC
(0.12A@24VDC)
• Power: 3 Watts (Max)
1. MOUNTING AND FIBER INSTALLATION
A. Secure the mounting xture to Busbar and Connect Fiber
B. Route the ber to Low-Voltage Compartment
NAVIGATION MAP
The HSM is equipped with a simple LCD display and a set of buttons which allow for navigation as well as
basic data display and configuration as shown below.

I. Insert the screw with the washer through
the ring-type connector and busbar.
II. Insert the washers and secure it with a
nut. Ensure the hole for fiber insertion is
pointed in the direction of the fiber routing.
III. Insert fiber into the holding fixture and
secure it with a 1.5mm hex screwdriver.
DO NOT bend fiber tighter than
12mm (1/2”) radius
DO NOT fasten or attach ANY
mounting hardware (tie-wraps,
etc.) to at least a 30cm (12”)
length of fiber
between the
portion of the
probe at high
voltage and
its first non-
energized point
of contact.
Avoid running fibers on sharp
edges or in the direction of the
fold of the boot to minimize
bending and damage to the fiber.
Keep away from sources of
excessive heat whenever possible.
Fiber probe shall not be attached
to surfaces with temperatures
exceeding 120°C or 248°F
unless used along with the high
temperature probe (sold separately).

Quick Start Guide
A. Connect to the Device
I. Connect a CAT5 Ethernet Cable directly between the
Ethernet ports on the router and HSM to be
configured.
II. Ensure the power is connected to the device and
a link is established, indicated by the LEDs.
III. Type in the IP address in the browser
(default: 192.168.1.50). A field has been provided on
the back sticker in case it has been changed
IV. From the home page you can navigate throughout
the rest of the site by using the navigation bar
on the left.
V. For additional information on how to navigate the
web utility, refer to: gracesense.com, product
support section - where you can find helpful
video tutorials.
Note: that if connecting via Ethernet to a computer
directly, the Internet Protocol Version 4 IP address
must be set in the network setting on the computer.
To do this, open Network and Sharing Center on the computer. Open the Ethernet Connection (or Local Area Connection) labeled
“Unidentified network”, then open Properties. From the List, select Internet Protocol Version 4 and then click Properties, where the IP
address can be set.
The first 3 numbers (separated by periods) of the Internet Protocol Version 4 IP address should match that of the HSM being used, while
the last number remains different. For example, if the HSM IP address is the default 192.168.1.50, the Internet Protocol Version 4 IP
address can be set to 192.168.1.3.
B. Factory Reset
To perform a factory reset:
I. Insert an object, such as the end of a probe, into the hole labeled “RST”
in the top left corner of the device and depress the concealed button
while applying power to the device. Keep the button depressed until both
the “SYS” and “COM” LEDs stay green (about 5 seconds).
II. Release the button and the device will restart with its default values.
