Liebert rpc manual

Adhere to all cautions and warnings on the unit and in this manual. Upon installation, follow all operating and user instructions. Each module has a small hole between the display and sensor RJ45 connectors to reset the card. For optimal flexibility, ensure that the modules match the power requirements of the application.

For a Liebert MPX rack PDU with more than one circuit, the outlets are named with numbers and are grouped by branch with a number referring to the proper circuit breaker.

Page Indicators Refer all faults to your local dealer, Vertiv representative or Vertiv Distributed Processing Applications Engineering. Page Operating Rack Pdu Cards After the unit is installed and assembled, verify the rack equipment is turned off. Connect the rack equipment to the receptacles. Page 42 This page intentionally left blank. The horizontal-mount units have up to nine receptacles. A Liebert MPH with single-phase input has a capacity up to 7. Three-phase input systems have a capacity up to For further details, refer to 6.

The monitoring unit can be handheld, mounted in or on the rack or mounted on a nearby wall. Refer to Table 2 for the dimensions. The unit can be installed on the face or the side of frame members. Installation requires attaching two brackets to the Liebert MPH, inserting four spring nuts into the rack and using the brackets to attach the Liebert MPH to the rack.

Refer to Figures 2, 3 and 4. The bracket is intended for attaching the Liebert MPH to the face of a frame member. Use four of the screws to attach a bracket to each end of the Liebert MPH. The supplied brackets have four holes that match holes on each end of the Liebert MPH. Tighten the screws firmly. Insert two spring nuts into the appropriate T-slot on the frame member.

Position the spring nuts to accommodate screws inserted through slots in the brackets. To move the spring nuts, press down on each with a small, pointed object and slide each into position. Hold the Liebert MPH in place and attach the top of the unit to the rack with tool-less fasteners.

The cord can be repositioned if it will need to enter from the front. To reposition the cord: 1. Remove the four screws retaining the input power plate. Reposition so that power cord enters from front. Reinstall the screws and tighten them. This will depend, in part, on whether the Liebert MPH would be best placed in the front of the rack or in the rear for routing power and communication wires. Bracket location also determines whether the Liebert MPH display is viewed from the front or rear of the rack.

When mounting the Liebert MPH, position the unit for ease of access and clearance. To attach the brackets: 1. Hold one mounting bracket against the side of the Liebert MPH, making sure that the end of the bracket with the round holes is against the unit. Attach the bracket to the unit with four Phillips head screws, tightening them firmly.

Figure 6 Liebert MPH ready for installation in a rack—horizontal-mount Front mounting holes Slots will attach to rack-mount rail 3. They use four captive nuts snapped into the rail holes and four screws to attach the Liebert MPH brackets to the rail.

As with all Liebert rack-mount equipment, obtain the appropriate size rack-mounting hardware kit for captive nuts and screws. A 2-meter cable and general mounting provisions are provided.

Figure 8 4. Determine the mounting location in the rack. Insert the Liebert MPH screw into the spacer sleeve. Insert the Liebert MPH screw into the spring nut and tighten securely with the screwdriver.

Liebert SN sensors are designed for installation in a Knurr Miracel without tools, but each may be placed in any area to monitor temperature and humidity levels. Only one mounting method is addressed in this manual: attaching a single sensor with a bracket to a Knurr Miracel frame member. Assemble the Liebert SN and sensor bracket: a. Insert the sensor bracket base into one end of the sensor support as shown in Figure Snap the sensor into the other end of the sensor support.

Choose where in the rack to install the sensor assembly. Emerson recommends placing the sensor in the area that is likely to be warmest.
