Test Cable Assembly P1B
WARNING
High voltage is present when the system is in operation. Use extreme care not to
contact wires during operation as serious injury or death to personnel could result.
The MTRCS contains high voltage sources and exposed rotating parts. Make sure
that power cables are disconnected from the MTRCS and that the refrigeration unit is
shut down before performing maintenance on the unit. Failure to comply with this
warning can result in serious injury or death to personnel.
1. Make sure external electrical power unit is turned OFF.
2. Disconnect P1B (Figure 6) from P1A (Figure 4), if connected.
3. Use a multimeter set to AC voltage scale to verify no voltage is present on external electrical power supply
output terminals.
4. Tag and disconnect wiring to external electrical power supply.
5. Use a multimeter set to ohms scale to make Cable Assembly P1B (Figure 6) continuity checks as shown in
Table 3.
