1: Introduction

This HZC Series light is designed for illumination of hazardous locations. It uses the latest in solid state lighting technology for long life, low maintenance, and high efficiency.

The unique optical design focuses light downward to where it is needed, giving improved efficiency over a conventional HID luminaire.

An internal power-factor-corrected supply allows it to be used from any nominal 347V-480V,

60/50Hz AC supply without any variation in light output.

Model HZC is suitable for use in the following locations:



HAZARDOUS LOCATIONS: CLASS I DIV 1 GROUPS C, D

CLASS II DIV 1 GROUPS E, F, G

Ta - Ambient Temp: -40 TO +65°C

Temp Rating: T5 (100°C) when Ta <= 45

Temp Rating: T4 (120°C) when 45<= Ta <=65



SUITABLE FOR WET LOCATIONS

Note: Save these instructions for future reference.

2: Installation

Warning:

To avoid the risk of fire, explosion, or electric shock, this product should be installed, inspected, and maintained by a qualified electrician only, in accordance with all applicable electrical codes.

Warning:

To avoid electric shock:





Be certain electrical power is OFF before and during installation and maintenance.

Luminaire must be connected to a wiring system with an equipment-grounding conductor.

Warning:







To avoid explosion:

 Make sure the supply voltage is within the luminaries’ voltage rating.

 Ensure the marked T Rating is less than the ignition temperature of the Hazardous Atmosphere.

Do not operate in ambient temperatures above those indicated on the luminaire nameplate.

Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.

Warning:





DO NOT let power cord touch hot surfaces

DO NOT mount near gas or electric heaters

Equipment should be mounted in locations and at heights where it will not be subjected to tampering by unauthorized personnel.

The use of accessory equipment not recommend by the manufacture may cause an unsafe condition

DO NOT use this equipment for other than intended use

Warning:









The technical data indicated on the Luminaire are to be observed.

Changes to the design and modifications of the Luminaire are not permitted

Only genuine Dialight replacement parts are to be used when unforeseen maintenance is required

Must install using NEMA 4x rated components to maintain rating.

For supply connections use wire rated for at least 90°C

Models HZC are factory supplied with 10 ft ( 3m ) of cable. If longer lengths of cables are required a minimum of 18awg (1.5mm diameter) is required. It is recommended that to ensure moisture does not flow through the cable a loop in the cord should be implemented where possible during installation. If this is not practical for the install than necessary precautions should be taken to prevent moisture entering the conduit thus entering the fixture.

Recommended mounting height: 8 feet to 24 feet (2.4 m to 7.3 m)

Pendent Mount Installation Steps: RECOMMENDED FOR USE WITH 360° OPTIC.



For maximum long term reliability and light output, the light must be installed in free air. o The HZC Series fixture design incorporates an over-temperature control circuit that reduces input power should internal temperatures reach a maximum level. As a result, light output may be reduced.



The HZC series fixture is threaded for 3/4” NPT in order to be assembled to conduit. o Calculate and measure required conduit length. o Feed the power cable through the conduit and into the junction box. o Attach the fixture to the conduit (using pipe sealant). o NOTE: If there is moisture present or chance of it in the conduit system than necessary precautions should be taken by the installer to prevent the moisture from entering thru the cable or conduit and entering the fixture o Insert 1/4-20 set screw in order to secure the fixture to the conduit.



Connect power cable conductors as follows: o For single phase (347 VAC):

 Green wire connects to Safety Ground.

 Black wire connects to Neutral

 Red wire connects to Live o For two phase (480 VAC): NOTE: DO NOT CONNECT TO SINGLE PHASE 480V

 Green wire connects to Safety Ground.

 Red wire connects to LINE1

 Black wire connects to LINE 2



Restore power and verify operation.

Stanchion Mount Installation Steps: RECOMMENDED FOR USE WITH 180° OPTIC.



For best optical performance Dialight Corportation recommends mounting unit at a 45° angle with respect to the vertical mounting pole or wall. o Refer to www.dialight.com

3: Maintenance



To avoid personal injury, disconnect power to the light and allow the unit to cool down before performing maintenance.

Warning: No user serviceable parts inside of fixture. Risk of electric shock. Removal of the lens will void the warranty.

1) Perform visual, mechanical and electrical inspections on a regular basis. We recommend routine checks to be made on a yearly basis. Frequency of use and environment should determine this. It is recommended to follow an Electrical Preventive Maintenance Program as described in NFPA 70B: Recommended Practice for Electrical Equipment.

2) The lens should be cleaned periodically as needed to ensure continued photometric performance. Clean the lens with a damp, non-abrasive, lint-free cloth. If not sufficient, use mild soap or a liquid cleaner.

3) Inspect the cooling fins on the luminaire to ensure that they are free of any obstructions or contamination (i.e. excessive dust build-up). Clean with a non-abrasive cloth if needed.

4) Do not operate if the lens is cracked or damaged. All fasteners should be properly seated
