1. Safety instructions
This product should be Installed and connected by skilled electri-
cians and instructed personnel in accordance with IEC/EN 60079-14
and the respective national legislation on electrical equipment for ex-
plosive atmospheres.
The national safety rules and regulations for the prevention of ac-
cidents, as well as the safety instructions, like this text set in bold-
italics in these operating instructions manual, shall be observed.
The luminaries must not be operated in Zone 0, 1 or 20 hazardous
areas.
The requirements of IEC/EN 60079-31 regarding excessive dust depo-
sits and temperature must be considered by the user. The indicated
surface temperatures are not related to a layer above 5mm thickness.
Before opening, electrical power to the luminaire must be turn off du-
ring at least 10minutes.
The temperature class and explosion group stated on the luminaire
shall be observed. To ensure adherence to the temperature class or
surface temperature stated on the type label of the luminaire, the per-
missible ambient temperature shall be observed.
Light
fi tting shall be used for their intended purpose and shall be un-
damaged and in a perfect and clean conditions.
Keep tightly closed when in operation.
The technical data indicated in point 3 as well as those indicated in
light fi tting, must be observed.
Modifi cations or design changes to this luminaries that can affect the
explosion protection are not permitted.
Avoid multiple, short time switching operation.
Only original EATON Crouse-Hinds Series spare parts may be used as
replacements and for repairs.
Repairs that affect the explosion protection may only be carried out
by EATON Crouse-Hinds Division or by a qualifi ed electrician in com-
pliance with the respective national regulations.
Prior to being put into operation, the luminaries shall be checked in
accordance with the instructions as per section 6.
Before initial operation, any foreign matter shall be removed from
light fi tting, do not keep this operating instruction manual inside of
the luminaire during its operation.
If the cable glands distributed with the luminaire will be replaced in
the fi eld, the restricted breathing "nR" properties must be checked.

4. Field of application
These light fi ttings are intended for use in potentially explosive atmosphe-
res in Zone 2 in accordance with IEC/EN 60079-10-1 and in Zones 21,
22 in accordance with IEC/EN 60079-10-2. The enclosure materials used,
including any external metal parts, are high quality materials that ensure a
corrosion resistance and resistance to chemical substances according to
the requirements for use in a ”normal industrial atmosphere”. As an exam-
ple, among others, the following:
- Copper free aluminum
- Epoxy powder fi nish
- Stainless steel
In case of use in an extremely aggressive atmosphere, please consult to
the manufacturer.
5. Use/Properties
This light fi tting can be use inside or outside to illuminate areas with gas or
dust potentially explosive atmospheres. The temperature class, explosion
group and permissible ambient temperature can be found in the tables and
technical data.
The data according to sections 2 and 4 shall be taken into account during
use. Applications other than those described are not permissible without a
written declaration of consent from EATON Crouse-Hinds Division.
During operation the instructions stated in section 7 of the operating ins-
tructions shall be observed. The sole responsibility with respect to the sui-
tability and proper use of these luminaries lies with the operator.
6. Installation
The IEC/EN 60079-14, relevant national regulations and the generally
recognized rules of engineering shall be applied for the installation and
operation.
Transport and storage of the luminaries is permitted in the original packa-
ging and specifi ed positions only.
Pay attention when installing, maintaining or repairing the light fi t-
tings, do not damage the fi re-fi nish of the glass surface by abra-
sions, sanding, small strokes, etc. that can weaken their mechanical
functions.
Intensive sun radiation in areas of high ambient temperatures may
cause inadmissible temperature rise inside of the luminaries. This
may result a decrease in lifetime of the ballast or electronic compo-
nents inside of the luminaries. Therefore those luminaries should be
switched off during daytime by a photocell control.
The improper installation and operation of light fi ttings can result in
the invalidation of the guarantee.
6.1 Mounting
Fixing dimensions are shown in table1
Luminaries are suitable for ceiling, wall or stanchion mounting.
The light fi tting may only lie fl at on and be fi xed torsion-free to the
fastening points provided for direct assembly.
Special attention shall be paid to the PE connections.
Warning: Over tightening might damage the light fi tting.
6.1.1 Ceiling and wall mounting
Mark and drill desired location on mounting surface. Secure with 1/4" (or
M6) bolts or lag screws (not provided). See Figure 1
6.1.2 Stanchion mount
Securely thread onto the appropriate NPT sized conduit. Tighten set screw
located in the conduit hub (see Figure 3).
6.1.3 Sealing
The cable glands shall have a degree of protection of IP66 or higher. Use
one of the following sealing methods to maintain the restricted breathing
properties.
6.1.3.1 Stanchion cover
Alternative sealing method for stanchion mount using RBPSI rubber sea-
ling plug (see Figure 4).
- Pull wiring conductors through hole in stanchion (up to 3-#12AWG con-
ductors).
- Cut a small slit in the center recess in the middle of the rubber sealing
plug and feed the conductors through the plug.
- Push the plug and wiring assembly into the slot in the cover so that it is
fl ush with the contour of the cover.
- Use silicone sealant to seal the plug to the cover and to fi ll the recess
where the wiring comes through the plug.
6.1.3.2 Ceiling and wall mount cover
Alternate sealing method for ceiling mount and wall mount. There are more
than four entries in ceiling or wall mount cover.
- Choose the entry to assemble the cable gland.
- Apply a small amount of HTL® lubricant to the thread of entries and
tighten the cable gland to the entry. Be sure there is a gasket installed
between the gland and housing.
- Insert suitable cable through gland and tighten the cable to the gland.
- All entries shall be sealed to restrict the entry of gases and vapors.
- All unused entries must be sealed with suitable plug.
6.2 Cable entries and blanking plugs
The cable gland shall have a degree of protection of IP66 or higher.
Unused entries shall be closed with certifi ed blanking plug in order to esta-
blish the minimum protection category.
The authoritative mounting guidelines for the cable glands used must be
observed.
Over-tightening might impair the protection category.
Attention: ensure that during tightening of the cap nut, complete ca-
ble does not start turning.
6.2.1 "nR" Restricted breathing
The restricted breathing "nR" properties must be preserved when using
cables and wires of suffi cient diameter (see IEC/EN60079-14).
If the cable glands included in the scope of delivery are replaced with other
cable glands, the
"
nR
"
properties must be checked before operation.
A restricted breathing test may be carried out as per Section 10.
6.2.2 "tb" Dust
If the cable glands included in the scope of delivery are replaced with other
cable glands, the cable glands and blanking plugs must be used in com-
pliance with IEC/EN 60079-31.
6.3 Electrical connection
The electrical connection of the luminaire must only be established by qua-
lifi ed electricians.
Be certain electrical power is OFF before and during installation and main-
tenance.
Luminaire must be supplied by a wiring system with an equipment groun-
ding conductor.
- Hang ballast housing on the cover module hinge hook (see Figure 5).
- Connect supply wires to luminaire wire leads (or terminals) per the
attached wiring diagrams using methods that comply with all applica-
ble codes (see Fig. 7, 14 and 15). Tighten all electrical connections
(2.5Nm).
