RePLACING AN exIStING moDeL HC600
wItH AN AutRoPAtH HC800
Flat Surface Mount
An optional adapter plate (part number 012718-003) is
available for converting an existing HC600 fl at surface
mount to an AutroPath HC800 fl at surface mount
without drilling new holes. See Figure 11 for dimensions.
The mounted AutroPath HC800 will have the following
offsets compared to the HC600 detector (when looking
straight at the wall/beam).
Left/right = 0”
Up/down = 1 inch lower
In/out = 0.3” closer to the wall/beam for the AutroPath
HC800.
Pole Mount
The AutroPath HC800 can be mounted to the same
pole as the Model HC600 using U-bolts. The AutroPath
HC800 will have the following offsets compared to the
HC600 detector.
Left/right = 0”
Up/down = 0” if the top U-bolt for the AutroPath HC800
is mounted 1” lower than the top U-bolt of the HC600
detector.
In/out = 0.8” closer to the pole for the AutroPath HC800.
24 VDC PoweR SuPPLy RequIRemeNtS
Calculate the total gas detection system power
consumption rate in watts from cold start-up. Select
a power supply with adequate capability for the
calculated load. Ensure that the selected power supply
provides regulated and fi ltered 24 Vdc power for the
entire system. If a back-up power system is required,
a fl oat-type battery charging system is recommended.
If an existing source of 24 Vdc power is being utilized,
verify that system requirements are met.
NoTe
If disconnection of power is required, separate
disconnect capability must be provided.
wIRING CABLe RequIRemeNtS
Always use proper cabling type and diameter for input
power as well as output signal wiring. 14 to 18 AWG
(2.5 to 1.0 mm
2
) shielded stranded copper wire is
recommended.
Always install a properly sized master power fuse or
breaker on the system power circuit.
NoTe
The use of shielded cable in conduit or shielded
armored cable is required for ATeX conformance.
In applications where the wiring is installed in
conduit, dedicated conduit is recommended.
Avoid low frequency, high voltage, and non-
signaling conductors to prevent nuisance eMI
problems.
CautIon
The use of proper conduit installation techniques,
breathers, glands, and seals is required to prevent
water ingress and/or maintain the explosion-proof
rating.
WarnInG
It is required that each conduit plug or fi tting be
wrench tightened to an appropriate installation
torque and meet the minimum thread engagement
requirements per the applicable local standards,
codes and practices in order to retain the defi ned
ingress protection rating. All unused entries must
contain appropriately rated conduit plugs or
fi ttings. PTFe sealant (or equivalent) should be
used on NPT threads.
