Physical Instructions for Installing an Encapsulated Hockey-Puck (HPP)
Instrument and LH2 Field-Mount Enclosure Apparatus
The Physical Instructions Supplement provides references and additional information for safely installing
and commissioning a Moore Industries’ Hockey-Puck instrument and LH2 Field-Mount Enclosure
Apparatus.
Instrument Labeling and Identication—The fully assembled apparatus consists of a Moore Industries’
Hockey-Puck unit securely mounted in an LH2 enclosure. Such an apparatus is intended for use in both
indoor and outdoor Hazardous (Classied) Locations where a degree of protection from windblown dust
and rain, splashing and hose-directed water, and protection from the formation of ice on the enclosure
is required. A series of selected Moore Industries’ 2-Wire hockey-puck style units mounted in the LH2
enclosure (consult factory for a list of the certied instruments) are certied as an Explosion-Proof and Dust
Ignition-Proof appartus in accordance with Factory Mutual Research ‘3600’ standard (NEC-based) and
as Flame-Proof in accordance with the CENELEC/ATEX Directive 94/9/EC (IEC-based). For applications
intended in North America and other related areas, the approval classications are stated on the externally
mounted metal ID Tag to be FM approved as Explosion-Proof for Class I, Division 1, Groups A, B, C and
D; Dust Ignition-Proof for Class II/III, Division 1, Groups E, F and G; T6 @ 60°C Maximum Operating
Ambient Temperature. In regards to protection from Environmental hazards/eects, the apparatus carries
a NEMA Type 4X rating with an Ingress Protection Code of IP66 as per IEC-529. For applications intended
in Europe and other related areas, the ID Tag clearly states that the apparatus is certied by ISSeP to be
Flame-Proof and marked as such:
II 2GD EEx d IIC; T6 @ Tamb. (-20°C ≤ Tamb. ≤+60°C). The temperature marking for dust
atmospheres is up to + 80°C. The maximum power param-eters are: Vmax = 42 VDC, Imax = 110 mA
and Pmax = 2W. Also, the tag clearly shows the CE marking denoting full compliance with the relevant
European Community directives applicable to the Process Instrumentation Industry. For 2-wire transmitters
certied and intended to be operated as either Intrinsically Safe, Non-Incendive (Class I, Div. 2) or Type
N; the power parameters are clearly stated on both the Instrument ID Label and the Apparatus ID Tag.
Also, the power parameters and cabling requirements are stated in the ‘Intrinsically Safe Barrier and Field
Installation Diagram’ that is included in the relevant User’s Manuals. This apparatus is designed in such
a way that it: a) does not give rise to physical injury or other harm due to contact, b) does not produce
excessive surface temperature, infra-red, electromagnetic, ionizing radiation and, c) have no non-electrical
dangers.
CAUTION: Read, understand and adhere to the manufacturer’s installation and operating procedures.
Substitution of components may impair the instrument’s Intrinsic Safety and/or Non-Incendivity. Keep cover
tightly closed. Do not open unit when energized. Do not open unit when either an explosive gas or dust
atmosphere is present. Cable entry temperature may exceed 70°C. Cabling to be suitable. Do not allow
layers of dust to accumulate on the surfaces of the equipment. Disconnect power before servicing.
Suitability for the Installation—To determine if a unit’s area classication approvals are appropriate for a
particular installation, rst inspect the classication labeling on the instrument and/or instrument enclosure
and the “Control Drawing for Installation” found in the User’s Manual (where applicable). Second, consult
the installation criteria for the approval or electrical standard agencies governing your location to determine
if the unit’s approvals are suitable for the installation. If the instrument’s labeling matches the agency
criteria and/or electrical codes for the area, the unit is suitable for the installation. To determine if the unit’s
electrical and environmental specications are appropriate for the installation, consult the “Specications”
table in the User’s Manual for that instrument. If the instrument’s electrical and environmental
characteristics are within the expected ambient operating conditions for the installation, the instrument is
suitable for the installation.
CAUTION: If for any reason you are uncertain as to whether the instrument’s specications or area
classications meet the operational or safety requirements for the installation,consult Moore Industries prior
to installation.
