General Information
GAI-Tronics Model 400-003 (120 V ac) and 400-004 (230 V ac) IEC/ATEX Zone 1 RigCom Stations are
designed for common-talk, or master/slave communication system operation in IEC/ATEX Zone 1
hazardous locations.
The unit provides push-to-call, release-to-listen operation, and has a local on/off volume-control switch to
activate and control the volume level for each station independently.
Models 400-003 and 400-004 have three M20 threaded entry holes for system, power, loudspeaker and
optional remote microphone and footswitch connection.
The Models 400-003 and 400-004 are designed to operate with other 400 Series RigCom stations, and
GAI-Tronics EZ Page Series of non-hazardous area rated equipment.

followed before operating the unit. Retain instructions for future reference.
2. Comply with all warnings on the unit and in the operating instructions.
3. Attachments not recommended by the product manufacturer shall not be used as they may cause
hazards.
4. Do not attempt to service this unit yourself. Opening or removing covers may expose you to
dangerous voltage or other hazards. Refer all servicing to qualified service personnel.
5. Electrical and mechanical installation and connection should be in compliance with all regulations.
This permanently connected apparatus must have an ALL-POLE MAINS switch with a contact
separation of at least 3 mm in each pole incorporated in the electrical installation of the building.
Installation
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.
CAUTION 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.
Securely fasten the enclosure to the mounting location, using (customer-supplied) 11mm (7/16-inch)
diameter steel mounting bolts and washers, or washer head bolts.

WARNING
Insure proper grounding to protective earthing.
Do not disconnect equipment while energized.
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.
Make certain no cover bolts are omitted. Use only those bolts supplied with the enclosure.
Recommended torque setting of cover bolts: 23 N-m (17 ft-lbs).
Mounting
NOTE:The mounting surface must be able to support the weight of the aluminum enclosure. The unit
weight is 10.5 kg (23.0 lbs).
The enclosure must be securely fastened with 11mm (7/16-inch) diameter steel mounting bolts located on
all four mounting feet. Stainless steel hardware is recommended for applications in corrosive
environments. Refer to Figure 2 for mounting dimensions.

Wiring
Station Wiring
While supporting the front cover, remove the 12 cover bolts on the enclosure flange. Pull the front cover
far enough away to expose the internal connections and disconnect any wiring between the front cover
and rear enclosure. Place the front cover aside.
Attach the cable glands to the holes on the bottom of the enclosure.
Cable glands must be certified to current ATEX and IECEx standards for type ‘d’ Flameproof protection
as well as ambient protection.
In rigid conduit systems, a sealing fitting must be installed in accordance with local codes.
Feed the low-voltage wiring in the left side hole and the power wiring through the right side hole. Refer
to Figure 2.
Attach the wires to the terminal blocks located on the PCBA within the enclosure. See Figure 4 and
charts for connection points and descriptions. Use one conductor (0.50 mm2to 4 mm2) per screw
terminal. Apply torque to 0.6 N-m.
If using the 10438-101 Auxiliary Microphone Assembly, connect the assembly to the station at terminal
block TB4-1 (+) and TB4-2 (−), shield to TB4-5, if used. The maximum distance from the station is 50
feet using 1 mm2wire.
If using an auxiliary footswitch assembly (customer-supplied), connect the assembly to the station at
terminal block TB4-8 (+) and TB4-9 (−), shield to TB4-5, if used. The maximum distance from the
station is 50 feet using 1 mm2wire.
In this operation, the auxiliary microphone replaces the speaker as the microphone, and the auxiliary
footswitch provides parallel functionality to the push-to-call switch.

System Line Balance
Each system requires termination of the audio pair wires with the 1 k/1-watt resistor (included with each
unit). The line balance resistor assembly is easily installed into the customer-supplied junction box.
NOTE:Only one line balance resistor assembly is needed per system.
For cable runs that are approximately 1219m (4,000 feet) or longer, it is recommended that the resistor
assembly be installed in a junction box (customer-supplied) that is close to the center of the system.
Refer to Figure 5 and Figure 6. The junction box must be suitable for the applicable hazardous location in
which it is located.

System Wiring
The maximum line length for the complete system, while still maintaining maximum output signal, is
4.5 km/15,000 feet for a system with less than ten stations using 1 mm2wiring, with stations spaced
equidistantly, and one station in the call mode at a time. For each station in call mode, the signal level
reduces by half. For systems with more than ten stations refer to Figure 7 for the maximum line distance.
