General Information
Product Overview
The GAI-Tronics SP2 station is a
modular industrial multicast VoIP (Voice
over Internet Protocol) communication
system. The Fiber Hazardous Area SP2
configuration is an indoor, multi-party,
handset/speaker amplifier station using ac
power with RTU control. They are
constructed of cold rolled steel with a
gray or safety orange powder-coat finish.
A number of options are available to add
to or modify station capabilities (see the
Features and Options sections below).
SP2 stations connect to an Ethernet
network so the loss of a single station
will not adversely affect the system as a
whole. The stations require a 100 Mbps
link to a switch or router using fiber optic
cable. To ensure the quality of SP2
audio, it is recommended that SP2
network traffic be isolated from other
devices and that network switches and routers be properly configured for IGMP (Internet Group
Management Protocol) snooping and multicast filtering. Maximum cable runs between Fiber SP2
stations and network switches are determined by the type of fiber optic cable used in the installation.

Installation
Important Safety Instructions
Read, follow, and retain instructions—All safety and operating instructions should be read and
followed before operating the unit. Retain instructions for future reference.
Heed warnings—Adhere to all warnings on the unit and in the operating instructions.
Attachments—Attachments not recommended by the product manufacturer should not be used, as
they may cause hazards.
Servicing—Do not attempt to service this unit by yourself. Opening or removing covers may expose
you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
Specific Conditions of Use: Flameproof joints are not to be repaired in the field. If the flame path is
damaged, the enclosure is to be removed from service and replaced with a new properly working
enclosure. The screws used for the body to cover must have a yield stress equal to or greater than
1100 MPa.
ATTENTION
—Install equipment without modification and according to all applicable local,
national and international electrical codes. North America - Consult the
National Electrical Code (NFPA 70), Canadian Standards Association (CSA
22.1), and local codes for specific requirements regarding your installation.
Class 2 circuit wiring must be performed in accordance with NEC 725.55.
These enclosures must be installed by trained, qualified and competent personnel. Installation must
comply with state and national regulations, as well as safety practices for this type of equipment.
WARNING
—Do not install this equipment in hazardous areas other than those indicated
on the approval listing in the “Specifications” section of this manual. Such
installation may cause a safety hazard and consequent injury or property
damage.
The mounting location must be flat and provide proper clearance, rigidity and strength to support the
enclosure and all contained devices. The enclosures are equipped with factory-installed hinges. The
enclosures should be mounted with hinges on the left.
WARNING
—Do not mount the enclosure with hinges on the top or bottom side.
Securely fasten the enclosure to the mounting location, using 3/8-inch (10mm) diameter steel mounting
bolts and washers, or washer head bolts.
WARNING
—Do not disconnect equipment while energized.
Ensure proper grounding to protective earthing.
Inspect and clean the machined flange flame joint surfaces of both the cover and box. Surfaces must be
smooth, free of nicks, scratches, dirt, or any foreign particle build-up that would prevent a proper seal.
Surfaces must seat fully against each other to provide a proper explosion-proof joint. Clean surfaces by
wiping with a clean lint-free cloth.
Apply a light coat of Killark “LUBG” lubricant to flange surfaces and close the cover. Install and tighten
all cover bolts to 30 ft.-lbs. Make certain no cover bolts are omitted. Use only those bolts supplied with
the enclosure.

Mounting the Enclosure
NOTE:The mounting surface must be able to support the weight of the aluminum enclosure. See the
Specifications section for the weights and dimensions of the unit.
Figure 2. Enclosure Mounting Details
The enclosure must be securely fastened with 3/8-inch (10mm) diameter steel mounting bolts located on
all four mounting feet. Stainless steel hardware is recommended in outdoor applications.
NOTE:Refer to the Killark Installation, Operation, and Maintenance Data Sheet enclosed with the unit
for additional information.
The suggested mounting height for all station enclosures is 48 inches (1219 mm) to the bottom of the
enclosure.

Cable Entries
Refer to Figure 3 for standard NPT conduit entries and Figure 4 for standard metric cable gland entries.
Ensure all unused openings are sealed with proper fittings per local standards. All metric cable entry
devices and blanking elements shall be certified in type of explosion protection flameproof enclosure “d”
with an IP66 rating, suitable for conditions of use, and must be correctly installed. Use field wiring
suitable for the ambient temperature. Any conduit NPT plugs (blanking elements) will need to be
explosion-proof with a Type 4X rating.

Field Wiring and Configuration
The SP2 Fiber Hazardous Area Station provides terminal blocks on the Termination PCBA located in the
rear of the enclosure for field wiring the power, speaker, and RTU connections. The Main PCBA,
mounted to the back of the front panel, provides the 600-ohm audio connection. The fiber termination
board is mounted on top of the Main PCBA and provides fiber optic termination for the Ethernet SFP
Transceiver.
NOTE:Consult the National Electrical Code (NFPA 70), Canadian Standards Association (CSA 22.1),
and local codes for the specific requirements regarding your installation. Install all equipment
without modification and according to the local and national codes. Class 2 circuit wiring must
be performed in accordance with NEC 725.55.
Station Ground
The station enclosure must be connected to earth ground.
1. Install a #6 ring lug on the ground conductor.
2. Secure it to the ground terminal located in the lower right corner at the back of the rear enclosure (see
Figure 5).
