MiCOM P632
Installation

The dimensions and mounting dimensions for surface-mounted cases are given in Chapter “Dimensional Drawings”. When the P632 is surface-mounted on a panel, the wiring to the P632 is normally run along the front side of the mounting plane. If the wiring is to be at the back, an opening can be provided above or below the surface-mounted case. Fig. 5-2 shows such an opening.

Fig. 5-2: Opening (cutout) for running the connecting leads to an 40 TE surface-mounted case.

The opening width for the 40 TE surface-mounted case: 213 mm (shown in this figure), for the 84 TE surface-mounted case: 435 mm. The other dimensions are the same for all cases.

Flush-mounted cases are designed for control panels. The dimensions and mounting dimensions are given in Chapter “Design”. When the P632 is mounted on a cabinet door, special sealing measures are necessary to provide the degree of protection required for the cabinet (IP 51).

Hint

Instructions for selecting the flush-mount method:

The P632 has increased mechanical robustness if either the surface-mounted case or – for the flush-mounted case – flush-mount method 2 (with angle brackets and frame) is used. In this case, test severity class 2 of the vibration test, test severity class of the shock resistance test on operability as well as test severity class 1 of the shock resistance test on permanent shock are applied additionally.

Hint

Dimensions of the panel cutouts:

Dimensional drawings of the panel cutouts for all cases and for the detachable HMI can be found in Chapter “Dimensional Drawings”.

For flush-mount method 1 (without angle brackets and frame), the procedure is as follows:

Before the P632 can be installed into a control panel, the local control panel (or the front element of the case for devices with detachable display) must be taken down. The local control panel is removed as described below:

1.

Remove both top and bottom hinged flaps from the device. (Lift/lower both hinged flaps 180° up/down. Hold them in the middle and bend them slightly. The side mountings of both hinged flaps can then be disengaged.)

2.

Remove the M3.5 screws (see Fig. 5-3).

3.

Then remove the local control panel.

⚫

The local control panel (or front element) is connected to processor module P by a plug-in connecting cable. Make sure the connector position is correct. Do not bend the connecting cable!

Then remove the lower M4 screws and only loosen the upper M4 screws (see Fig. 5-3). Now insert the P632 into the panel opening from the rear so that the upper M4 screws fit into the corresponding holes. Then tighten all the M4 screws. After this, replace the local control panel.

graphics/symbols/Warning.png WARNING

⚫

When replacing the local control panel, take care not to tighten the M3.5 screws with too much strength! (Fastening torque 1.5 to 1.8 Newton meters.)

Hint

If the control panel thickness is ≥ 2 mm, the longer M3.5 and M4 bolts must be used. Longer screws are enclosed within the device packing.

The P632 has increased mechanical robustness if either the surface-mounted case or for the flush-mounted case flush-mount method 2 (with angle brackets and frame, see Fig. 5-5) is used.

For flush-mount method 2 (using the angle brackets and frame), the procedure is as follows:

1.

Remove the screws as shown in Fig. 5-4, ➀ and mount the enclosed angle brackets using these same screws.

2.

Then push the device into the control panel cutout from the front.

3.

Secure the device to the control panel by using the enclosed M6 screws (see Fig. 5-5).

4.

Assemble the cover frame and snap-fasten onto the fixing screws.

The cover frame width of the 40 TE surface-mounted case is: 280 mm, of the 84 TE case is: 486 mm. The cover frame height is for all cases: 204 mm.

A rack mounting kit can be used to combine a flush-mounted 40 TE case with a second sub-rack to form a 19″ mounting rack (see Fig. 5-6). The second sub-rack can be another device, for example, or an empty sub-rack with a blank front panel. Fit the 19″ mounting rack to a cabinet as shown in Fig. 5-7.
