5.3.1Introduction

This section gives an overview of typical system connections using the network controller.

•Connecting the mains (see section 5.3.2).

•Connecting the network (see section 5.3.4).

•Connecting a configuration PC (see section 5.3.5).

•Connecting audio inputs (see section 5.3.6).

•Connecting audio outputs (see section 5.3.9).

•Connecting control inputs (see section 5.3.8).

•Connecting control outputs (see section 5.3.9).

•Connecting the RS232 port (see section 5.3.10).

•Inserting a compact flash card (see section 5.3.11).

Warning

For safety reasons you must use an external circuit breaker. Install in accordance with the local Electrical and Building Code, e.g. for USA and Canada in accordance with NEC/CEC and for Germany in accordance with VDE0108-1. To reduce the risk of electric shock do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. See section 1.2 Intended audience.

5.3.2Connecting the mains

Proceed as follows to connect the network controller to the mains:

1Select the correct local mains voltage using the voltage selector on the rear of the network controller (see table 5.1).

table 5.1: Voltage selector and fuse

Selector	Mains voltage	Fuse
	V(AC)
115	100 - 120	T2.5A 250V
		(UL 248)
230	220 - 240	T2A H 250V
		(IEC 60127)

2Put the correct type of fuse in the network controller (see table 5.1).

3Connect the mains cord to the network controller.

4 Connect the mains cord to a locally approved mains outlet.

5.3.3Connecting back-up power

Connect the back-up supply to the back-up power connector on the back of the network controller. Refer to figure 5.4.

Use the connector supplied with the unit. The fuse for the back-up supply is inside the unit. The back-up supply input is protected against voltage reversal. The back-up voltage range is 43 to 56 V. The system voltage from the system bus is a constant 48 V. The power supply to the units that receive power from the system bus is not affected by a changing back-up battery voltage.

Note

When the network controller has a back-up power supply connected, the network controller cannot be switched off just by the mains on/off switch (9). The battery connection must also be removed.

Warning

Never ground the positive terminal of the battery, as this will damage the Praesideo equipment.

If the back-up power supply (battery) is grounded, always connect the negative terminal

(0)first and the positive terminal (+) second. Disconnect in reverse order: disconnect the positive terminal first and the negative terminal second. This avoids excessive ground loop

currents.
