The use of TO MAKE ELECTRICAL CONNECTIONS washers below the screw head is recommended. Mounting 1. Remove (unlatch) the connector from the AWM5000. torque is 1,1 N m (9.75 in lb) max. for steel screws, or 2. Hand-crimp the interface wire to the appropriate pin on 0,75 N m (6.75 in lb) max. for brass screws. connector. Suggested tool: AMP Hand-Crimp Tool, part number 58074-1 and terminating head 58336-1. NOTICE 3. Insert the terminal contacts into the connector housing after • When making flow connections to a mounted sensor, the the carrier strip (lead-frame) is removed. AWM5000 must be supported at the flow adapter. 4. Reconnect (latch) connector to the AWM5000 device. • If end adapters are twisted with respect to the flow tube during installation, the seal between O-ring and flow tube CLEANING will be broken, causing a small temporary leak. The leak CAUTION can be as high as 1 psi, or may remain within PRODUCT DAMAGE specification. It will self-heal as the O-ring conforms. • Do not use ultrasonics. About 85% of the leak will be gone within approximately • Do not use III Tri-chloroethane, methylene chloride, methyl 24 hours, with complete recovery within approximately pyrrolidone or any oxidizing type acid such as formic acid. 48 hours. • Cover the ends of the tube during cleaning because certain • Do not expose ports to forces greater than 1 kg [2 lb] in a solvents may attack the epoxy which seals the chip tube to direction perpendicular to the port centerline. the ceramic substrate. • Torque on ports should not exceed 4,52 N m [40 in lb]. Failure to comply with these instructions may result in product damage.
