2.2.6 Sealing the Interconnect Cable
^
When the conduit is routed through
hazardous areas, the ends of the conduit
must be sealed to prevent hazardous
gases from escaping into non-hazardous
areas. Consult local authorities for
approved sealing methods in hazardous
areas.
If the differential pressure between the ends of the connector cable is less than
one atmosphere, use one of the following cable sealing techniques:
1. Z Y 5 cable seal similar to Bently Nevada part number 10076-AA.
2. B e n t l y Nevada low-pressure cable seal, part number 43501.
2.3 Power and Signal Connections
Bently Nevada supplies interconnect cables with terminal lugs and a 3-socket
mating connector for the 330400 and the 330425 Accelerometer. Interconnect
cables are sold separately (see 1for the cable options).
At the accelerometer end, tighten the 3-socket mating connector to the
accelerometer's MIL-C-5015 connector. At the monitor end of the cable, use the
wiring instructions for the appropriate monitoring system below.
Note: the wiring instructions assume that the interconnect cable is the
standard Bently Nevada cable part number 16925 - XX.
2.3.1 3300 MONITORING SYSTEM
Connect the cable "A" lead to the "IN" terminal on the monitor, the "B" lead to the
"PWR" terminal, and the "C" lead to the "COM" terminal. The terminal connections
for the 3300 Dual Acceleration Monitor appear in Figure 2-1. Refer to the 3300/25
Peak and 3300/26 RMS Dual Acceleration Input Monitor Maintenance Manual
(part number 80181-01 and 86801-01) for further information.
2.3.2 2201 MONITORING SYSTEM
Connect the cable "A" lead to "SIG/A" terminal on the monitor, the "B" lead to
"PWR/B", and the "C" lead to "COM". The terminal connections for the 2201
Monitoring System appear in Figure 2-2. Refer to the 2201 Monitoring System
Operation and Maintenance Manual (part number 100875-01) for further
information.
