Installation Restrictions and Precautions
●
Power supply module installation restrictions
Redundant configuration is not allowed for the power supply module. Does not use slot
P2.
●
CPU module installation restrictions
Redundant configuration is not allowed for the CPU module.
●
STARDOM module installation restrictions and precautions
STARDOM modules other than the power supply modules (NFPW426, NFPW441,
NFPW442 or NFPW444) and CPU module (NFCP050) cannot be installed to the base
module for DTSX3000.
Do not install other STARDOM modules.
●
Optical switch module installation precautions
When installing the optical switch module, to prevent it from contacting with the front
panel of the distributed temperature sensor, always install the sensor first. Similarly, on
removal, always remove the optical switch module first. When installing the optical
switch module, ensure that the gasket of the front panel is not loosened.
