5.4.3 Command
Module internal
power supply
The Command Module may be fitted with an integral power supply and battery
charger. The relevant connections are shown below, although these will normally be
made when the unit is manufactured. This diagram applies only to Command Modules
fitted with an integral supply, although connections to alternative external power
supplies will be similar.
1.
BAT + and – : battery recharge terminals. Bat + (red wire) goes to the positive
terminal of the first battery and Bat – (black wire) to the negative terminal of
the second battery. The negative terminal of the first battery is connected to the
positive terminal of the second battery with the yellow cable supplied (see section
5.4.4, “Backup batteries”).
2.
+ and – : 24V DC supply connecting to the 24VDC and 0V terminals on the
Command Module terminal block respectively (see section 5.4.2, “Command
module power supply connections”).
3. NC and C : Volt-free fault relay contacts to connect to the “I/P 1” or “I/P 2”
terminals on the Command Module terminal block (see section 5.3.2, “Command
module terminal block connections”). Polarity of the wires on these terminals is not
important. See section 4.3.27, “Mains check enable”
4. 24V supply fuse: 5 x 20mm 500mA type.
5. Mains supply terminals: This unit should only be powered by mains cable with
an earth conductor. Connections are as follows:
Neutral (N): Blue wire (White in U.S)
Earth ( ): Green and Yellow wire
Live (L): Brown wire (Black in U.S)
6. Mains fuse: For 230V operation, a standard 3A, 5 x 20mm mains fuse.
