• Before entering a hazardous area, close both the battery
door and USB/SD card door, and secure both with lock
screws.
• The battery access cover is not to be removed while in a
hazardous area.
• The USB/SD access door is not to be removed while in a
hazardous area.
• Replace batteries only in a non-hazardous area.
• Use only Duracell Model MN1500 AA alkaline primary cell
batteries.
• The USB connection-data transmission and power input- are
restricted to be used in a non-hazardous area only.
• The non-hazardous area USB apparatus –computer port,
wall supply, etc., connected to the USB port of the HHC,
must be assessed and conform to section 6.2.5 of EN60079-
11. This precaution is to protect the integrity of the safety
components within the HHC, which insures its intrinsic safety
rating while in the hazardous location.
• When using non- assessed USB equipment, accessory
part number 101C225-01, USB protection device, is to be
inserted between the HHC USB port and the non-assessed
apparatus.
• Do not power the calibrator by USB cable in a hazardous
area; this action will invalidate the calibrator’s intrinsic safety.
• Intrinsically safe installation diagrams, entity parameters and
warnings are included in drawing 825A028 included in the
supplemental I.S. manual.
