5.2.10 Mounting the Housing without a Back box

The housing can be mounted on a flat surface, without a back box, using four suitable screws in the

outer fixing holes, as shown in the illustration below. When the NIRC housing is without a back box

the cables should enter and leave the housing through the two knock-outs in the sides of the housing.

Figure 20. Mounting the NIRC housing without a back box

Caution: Do not distort the NIRC housing when it is mounted with or without a back box. To

prevent distortion only mount the NIRC housing on a smooth, level surface and do not over-

tighten the fixing screws! If the housing is distorted the top section will not fit properly and

could fall off.

5.3 Preparing the Room Bus and Power Cables

It is important to prepare the cables appropriately and to guide the wires correctly inside the housing

in order to avoid the wires pressing on the printed circuit board which could result in damage and also

prevent the top section from closing properly.

The following instructions apply to the room bus cables, the power supply cable and the corridor lamp

cables.

5.3.1 Stripping the Outer Jacket of the Cables

The first step is to strip the outer jacket of the cables to a length of 6.0in (150mm), then position the

cable in the back box so that only the stripped wires enter the NIRC housing.

If the cable contains more than four wires the excess wires should be carefully stowed in the back box, away from the printed circuit board and other components to avoid electrical faults and safety problems. Details of the room bus connections are given in 5.4.1, 4-Pole Connector Terminal (NICT-4AA), page 31.

It is also used for the 24Vdc power supply from the room controller to the corridor lamp. The 2-pole terminal connector has two screw terminals. Each terminal accepts one wire (up to wire size 14 gauge (1.5mm²) (1.4mmØ) or two wires (each up to 18 gauge (1mm²) (1.15mmØ).

The connection point on the room controller circuit board for the power supply is shown in section 5.3.2 on page 28. The power supply wires should be guided around the sides of the room controller housing and held in place by the wire holding clip, as shown in the following illustration: Figure 36.

Power supply and corridor lamp power connections NIRC3 The corridor lamp (NICL2) that must be used with the NIRC3 is powered directly from the 5.5V room bus power and does not require a separate 24 volt power connection, therefore the NIRC3 is not equipped with the 24 volt power outputs. IMPORTANT: Because the NIRC3 does not have 24V power outputs, the corridor lamp (NICL) should not be connected to the NIRC3.
