INSTALLATION AND SERVICE INSTRUCTIONS FOR MODEL 191X INCANDESCENT

LIGHT FOR USE IN HARSH ENVIRONMENTS/HAZARDOUS LOCATIONS

SAFETY MESSAGE TO INSTALLERS, USERS AND MAINTENANCE PERSONNEL

It is important to follow all instructions shipped with this product. This device is to be installed by a
trained electrician who is thoroughly familiar with the National Electrical Code or Canadian Electrical
Code and will follow the NEC or CEC Guidelines as well as local codes.

The selection of the mounting location for the device, its controls and the routing of the wiring is to
be accomplished under the direction of the facilities engineer and the safety engineer. In addition,
listed below are some other important safety instructions and precautions you should follow:

• Read and understand all instructions before installing or operating this equipment.

• Do not connect this light to the system when power is on.

• After installation, ensure that the set screw is properly tightened and that threaded joints are
fully engaged.

• After installation, test the light system to ensure that it is operating properly.

• After testing is complete, provide a copy of this instruction sheet to all operating personnel.

• Establish a procedure to routinely check the light installation for integrity and proper operation.

Failure to follow all safety precautions and instructions may result in property damage,
serious injury, or death to you or others.

I. GENERAL.

The Model 191X is an incandescent lighting fixture. It is UL listed for operation in harsh
environments and hazardous locations, and has been investigated by UL as meeting Type 4X
and IP66 enclosure requirements. The unit is rated for operation on AC or DC voltages from
24 to 250-volts.

The unit will accommodate up to a 100-watt lamp (bulb shape A-19). Actual lamp wattage used
must be determined by the hazardous location temperature requirement for the specific installation.

II. INSTALLATION.

A.Unpacking.

WARNING

Damaged globes can lead to explosions which could result in serious injury or death.

After unpacking the Model 191X, examine it for damage that may have occurred in transit. If the
equipment has been damaged, do not attempt to install or operate it, file a claim immediately with
the carrier stating the extent of the damage. Carefully check all envelopes, shipping labels and tags
before removing or destroying them.

B.Mounting.

The Model 191X has provisions for mounting to

3

/4" pipe and may be mounted in any position.

Before mounting, ensure that mating threads are clean. Thread the fixture onto the

3

/4" pipe and

secure with the set screw.

C.Lamp Selection.

CAUTION

To reduce the risk of fire or explosion, do not install in a hazardous location if the operating

temperature exceeds the hazardous atmosphere’s ignition temperature.

Before proceeding, consult product nameplate as a guide for determining the proper lamp
wattage and supply wire insulation rating for the specific installation.

D.Electrical Connections.

WARNING

To avoid electrical shock hazards, do not connect wires when power is applied.

1. To remove the globe assembly, grasp the metal ring attached to the globe and turn
it counterclockwise.

WARNING

To maintain effectiveness of explosion-proof enclosure, do not damage globe or threads while

disassembling or reassembling unit. Lubricated threaded joints exposed for long periods of time may

attract small particles of dirt or other foreign materials. Body and cover joints should be

reassembled immediately,with all threads fully engaged.

2. Remove the two screws which secure the insulator and lamp socket to the housing.

3. Pull the supply wires into the housing. Connect the supply wires to the terminals on the
lamp socket. If required, the green screw in the housing is provided for connection to an
earth ground.

4. Secure the insulator and lamp socket to the housing.

5. Install the appropriate lamp in the socket.

6. Replace the globe assembly. Ensure that the globe assembly is seated securely against
the gasket.

7. Test the light for proper operation.

III. MAINTENANCE.

WARNING

To prevent ignition of hazardous atmospheres, disconnect the fixture from the supply circuit

before opening. Keep tightly closed when in operation.

SAFETY MESSAGE TO MAINTENANCE PERSONNEL

Listed below are some important safety instructions and precautions you should follow:

• Read and understand all instructions before operating this system.

• Any maintenance to the light system must be done with the power turned off.

• Any maintenance to the light system must be performed by a trained electrician in accordance with NEC
or CEC Guidelines and local codes.

• Never alter the unit in any manner. Safety in hazardous locations may be endangered if additional
openings or other alterations are made in units specifically designed for use in these locations.

• The nameplate, which may contain cautionary or other information of importance to maintenance
personnel, should not be obscured if exterior of housings used in hazardous locations are painted.

• Broken globes can lead to explosions which could result in serious injury or death. If the globe is
damaged in any way, the complete globe assembly MUST be replaced.

• The only electrical component to be replaced by the customer is the lamp.

A.Lamp Replacement.

WARNING

To avoid electrical shock hazards, do not replace the lamp when power is applied.

1. To remove the globe assembly, grasp the metal ring attached to the globe and turn it
counterclockwise. If the globe assembly will not unscrew, place a screwdriver blade against
one of the four bosses on the metal ring attached to the globe. Gently tap the screwdriver
handle to loosen the globe assembly from the base casting.

WARNING

To maintain effectiveness of explosion-proof enclosure, do not damage globe or threads while

disassembling or reassembling unit. Lubricated threaded joints exposed for long periods of time may

attract small particles of dirt or other foreign materials. Body and cover joints should be

reassembled immediately,with all threads fully engaged.

2. Replace the defective lamp with an exact replacement.

3. Replace the globe assembly. Ensure that the globe assembly is seated securely against
the gasket.

4. Test the light for proper operation.

B.Cleaning Enclosure.

NOTE

Maintenance procedures sometimes require fixtures to be hosed down for good housekeeping.

The fixture should be cleaned periodically to maintain maximum light output. Only mild,
non-abrasive cleaning agents should be used. The glass globe should be regularly inspected for
scratches and chips, and, if damaged, must be replaced.

C.Lubrication.

Threaded Globe Assembly joint should be well lubricated with petroleum or a soap-thickened
mineral oil. If corrosive products have accumulated on the joint and cannot readily be removed
with solvents, the parts should be discarded and replaced.

WARNING

Never use an abrasive material or file to remove corrosive products from threaded surfaces.

In extremely corrosive locations, equipment should be periodically inspected to guard against

unusual deterioration and pitting, since this may weaken the enclosure structurally.

D.Service.

The Federal factory will service your equipment or provide technical assistance with any
problems that cannot be handled locally.

Any units returned to Federal Signal for service, inspection, or repair must be accompanied by
a Return Material Authorization. This R.M.A. can be obtained from the local Distributor or
Manufacturer’s Representative.

At this time a brief explanation of the service requested, or the nature of the malfunction,
should be provided.
