Safety Messages to Installers

WARNING
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 Electric Code/Canadian Electric Code and will follow the NEC/CEC Guidelines as well as local codes. The selection of 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.
• 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.
• After installation, ensure that all screws are properly tightened.
• 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.

Overview of the Fixture Mounts

The optional fixture mounts are designed to replace the original pendant mount on the explosion-proof light housing. Wiring must comply with Article 500 of the National Electrical Code and the local authority having jurisdiction. For Marine applications, all wiring, including supply wire, must be stranded wire and meet USCG (CFR46) Sections (110-113.)

Installing the CMXC-SB Ceiling Mount

To install the ceiling mount on the support surface:

1. See Figure 1. Secure the ceiling mount to the support surface using the four external mounting slots.
2. Remove the terminal block from the ceiling mount by removing the two screws securing it to the fixture.
3. For instructions on wiring the beacon, see page 8 for the DC beacon or page 9 for the AC beacon. Figure 1 Model CMXC-SB ceiling mount

THE CMXC-SB IS NOT SUITABLE FOR USE WITH THROUGH-BRANCH CIRCUIT CONDUCTORS .

Installing the PMXC-SB Pendant Mount

To install the pendant mount on a 3/4-inch pipe:

1. Ensure that the mating threads are clean.
2. Thread the pendant mount onto the 3/4-inch pipe and secure it with the setscrew.
3. Remove the terminal block from the ceiling mount by removing the two screws securing it to the fixture.
4. For instructions on wiring the beacon, see page 8 for the DC beacon or page 9 for the AC beacon. Figure 2 Model PMXC-SB pendant mount

Wiring the DC Beacon to the CMXC-SB and PMXC-SB

The CMXC-SB is not suitable for use with through-branch circuit conductors.

Warning
SHOCK HAZARD—To avoid electrical shock hazards, do not connect the light to the supply circuit when power is applied.

NOTICE
REVERSE POLARITY/MISWIRING—DC strobe units are polarity- and voltage-sensitive and may be damaged by an incorrect electrical hookup. When connecting the 24 Vdc strobe unit to the voltage supply lines, polarity must be observed. In addition, damage will result if the voltage rating of the particular model is exceeded.

See the figures on pages 6 and 7. To wire the DC beacon to the fixture terminal block:

1. Connect the positive (+) power source wire to the terminal block screw marked L+.
2. Connect the negative (–) power source wire to the terminal block screw marked N–.
3. If required by local building codes, connect the earth-ground wire to the green screw in the fixture mount.
4. Place the terminal block in the fixture mount and secure it with the mounting screws.
5. Plug unused conduit entries with the provided close-up plugs.
6. To prevent galling and ease future maintenance, ensure that the fixture mount threads are clean and lubricated.
7. Thread the fixture clockwise into the fixture mount and hand tighten it securely.

Wiring the AC Beacon to the CMXC-SB and PMXC-SB

The CMXC-SB is not suitable for use with through-branch circuit conductors.

WARNING

• SHOCK HAZARD—To avoid electrical shock hazards, do not connect the light to the supply circuit when power is applied.
• To reduce shock hazards during maintenance POLARITY MUST BE OBSERVED when connecting AC units to the power source.

See the figures on pages 6 and 7. To wire the AC beacon to the fixture terminal block:

1. Connect the phase (hot) power source wire to the terminal block screw marked L+.
2. Connect the common (neutral) power source wire to the terminal block screw marked N–.
3. If required by local building codes, connect the earth-ground wire to the green screw in the fixture mount.
4. Place the terminal block in the fixture mount and secure it with the mounting screws.
5. Plug unused conduit entries with the provided close-up plugs.
6. To prevent galling and ease future maintenance, ensure that the threads on the fixture mount are clean and lubricated.
7. Thread the fixture clockwise into the fixture mount and hand tighten it securely.

Installing the WMXC-Series Wall Mount

To install the wall mount fixture on the support surface:

1. See Figure 3. Secure the wall mount to the support surface using the two external mounting holes.
2. Use wire nuts to connect power and ground as described in the next sections. Figure 3 Model WMXC-SB wall mount

Wiring the Non-supervised DC Beacon to the WMXC-SB

WARNING
SHOCK HAZARD—To avoid electrical shock hazards, do not connect the light to the supply circuit when power is applied.

NOTICE
REVERSE POLARITY/MISWIRING—DC strobe units are polarity- and voltage-sensitive and may be damaged by an incorrect electrical hookup. When connecting the 24 Vdc strobe unit to the voltage supply lines, polarity must be observed. In addition, damage will result if the voltage rating of the particular model is exceeded.

To wire the non-supervised DC beacon to the fixture terminal block:

1. Connect the positive (+) power source to the black wire.
2. Connect the negative (–) power source to the white wire.
3. If required by local building codes, connect the green/yellow wire to earth ground.
4. To prevent galling and ease future maintenance, ensure that the fixture mount threads are clean and lubricated.
5. Thread the fixture clockwise into the fixture mount and hand tighten it securely.

Wiring the Supervised DC Beacon to the WMXC-4 and WMXC-4R

WARNING
SHOCK HAZARD—To avoid electrical shock hazards, do not connect the light to the supply circuit when power is applied.

NOTICE
REVERSE POLARITY/MISWIRING—DC strobe units are polarity- and voltage-sensitive and may be damaged by an incorrect electrical hookup. When connecting the 24 Vdc strobe unit to the voltage supply lines, polarity must be observed. In addition, damage will result if the voltage rating of the particular model is exceeded.

The Models WMXC-4 and WMCX-4R wall mounts have five leads: two red, two black, and one green/yellow.
