Designed to interface directly with the 3500/15 power supply system, the Bently Nevada 133300-01 provides regulated low-voltage DC input capabilities to the 3500 machinery protection rack. This rear-mount module accepts 20 to 30 VDC and conditions the incoming primary power before routing it to the internal backplane. Engineered for high-reliability environments, it is crucial for maintaining continuous machinery monitoring and protecting critical rotating assets from unexpected power interruptions.

The 133300-01 is specifically paired with the low-voltage DC variant of the 3500/15 power supply. It is physically and electrically incompatible with the high-voltage AC/DC modules (such as 129767-01 or 120739-01). Always verify the voltage rating of your front-facing 3500/15 module before hot-swapping or replacing rear input elements.
In dual-redundant setups, ensure both low-voltage DC sources originate from independent breakers or power feeds. If both inputs are tied to the same feeder circuit, the system redundancy is effectively bypassed. Avoid routing raw, unfiltered field DC directly to these terminals; use external line conditioning if long cable runs are subject to inductive switching noise.
Use a minimum wire gauge of 14 AWG (2.1 mm2) to prevent excessive voltage drop over runs exceeding 10 meters. Ensure terminal block screws are torqued exactly to 0.56 Nm (5 in-lb) to maintain secure connections under continuous high-frequency machinery vibration.
De-energize all primary DC power feeds before installing, removing, or wiring the rear input module. Servicing connections while energized can cause dangerous electrical arcing, localized contact damage, or critical backplane component degradation.
Ensure the main 3500 rack power switch is in the OFF position and the source DC breaker is locked out.
Align the 133300-01 module card edges with the card guides in the designated rear half-height slot.
Slide the module firmly forward until its connector mates completely with the backplane connectors.
Secure the captive faceplate mounting screws and attach the terminal cover after finalizing field wiring.
