SAFETY INSTRUCTIONS
Instructions for the Reliance Controls ARM
Series Automatic Transfer Switch
THE RELIANCE CONTROLS ARM SERIES AUTOMATIC
TRANSFER SWITCH (ATS) IS NOT FOR “DO-IT-YOURSELF”
INSTALLATION. It must be installed by a qualified electrician
thoroughly familiar with all applicable electrical and building
codes.
The Reliance Controls ARM Series is an automatic transfer
switch purpose-designed to provide a safe and simple method
of powering a dwelling from a permanently installed backup
AC power source. The electrical-over-mechanical transfer
switching and interlocking system prevents accidental feedback
of backup power onto utility lines.
This manual has been prepared for familiarizing servicing
dealer/installer with the design, application, installation and
servicing of the equipment.
Read the manual carefully and comply with all instructions.
This manual or a copy of this manual should remain with the
switch. Every effort has been taken to make sure that the
contents of this manual are accurate and current.
The manufacturer reserves the right to change, alter or
otherwise improve this literature and the product at any time
without prior notice and without any obligation or liability
whatsoever.
The manufacturer cannot anticipate every possible
circumstance that might involve a hazard.
The warnings in this manual, tags and decals affixed to the
unit are, therefore, not all-inclusive. If using a procedure, work
method or operating technique the manufacturer does not
specifically recommend follow all codes to ensure safety for
personnel.
Many accidents are caused by failing to follow simple and
fundamental rules, codes and precautions. Before installing,
operating or servicing this equipment, read the SAFETY RULES
carefully.
The publications that cover the safe use of ATS and installation
are the following NFPA 70, NFPA 70E, UL 1008 and UL 67. It is
important to refer to the latest version of any standard/code to
ensure correct and current information. All installations must
comply with local municipal, state and national codes.
Before Installation
WARNING
Per OSHA 3120 Publication; “lockout/tagout” refers to
specific practices and procedures to safeguard individuals
from the unexpected energization or startup of machinery
and equipment, or the release of hazardous energy during
installation, service or maintenance activities.
WARNING
Be certain that the power from the utility is turned off
and all backup sources are locked out before starting this
procedure. Failure to do so could result in serious injury
or death. Remember, automatic start generators will start
upon loss of utility mains power unless locked in the “off”
position. Consult the generator operator manual section to
locate the ATS CONTROL and ENGINE CONTROL modules to
make sure both switches are in the OFF position.
CAUTION
Consult with your Local municipal, State and National
electrical codes for proper mandatory wiring methods.
Carefully unpack the ATS. Inspect closely for any damage
that might have occurred during shipment. Check that all
packing material is completely removed from the ATS prior
to installation. Handle ATS carefully when installing. Do not
drop. Protect the ATS against impacts at all times and against
construction grit and metal chips. Never install an ATS that is
damaged.

As of January 1, 2017, enhanced UL 67 safety requirements
took effect, applying to all panelboards and loadcenters with
service equipment applications. To comply, any single service
disconnect panelboard or loadcenter must have provisions such
that, when the service disconnect is opened, no person in the
field servicing the equipment load side can make accidental
contact to live circuit parts. Barriers to protect against
unintended contact shall be constructed in such a way that
they are easily installable and removable without contacting
or damaging bare or insulated live parts. The barrier could be
installed on the ARM, panelboard or loadcenter.
We elect to use different style mounting cabinets at times.
Below gives you dimensions for mounting either style you
may receive. Style 1 may require hub covers for top openings,
use Siemens type HS hub cover or similar and hub hardware
ECHSXXX or similar.
Style 1 – use 1/4 in. hardware (not included)
Style 2 – use 1/4 in. hardware (not included)
NOTICE
Do not route wires below or above the drive plate, as this
will impede movement of the drive plate
Do not route wires in the shaded
zones.
