terminals in your plug, proceed as follows:
The wire which is coloured Green and Yellow must be connected to the terminal in the plug which
is marked with the letter E or by the earth symbol.
The wire which is coloured Blue must be connected to the terminal in the plug which is marked
with the letter N
The wire which is coloured Brown must be connected to the terminal in the plug which is marked
with the letter L
Ensure that these colour codes are followed carefully in the event of the plug being changed

Connecting Up
Before You Start
Ensure the DPS-4 power supply is NOT connected to the Mains and is turned OFF.
The Power supply can be positioned anywhere within reach of the console and an available power socket, but is best rackmounted
in a position where airflow through the vents is not obstructed and where the power switch or cables cannot be accidentally
knocked. Connect the multi-way power cable between the DPS-4 External Power Supply and the console’s connector.
Screw the connector locking ring clockwise on both units to secure the cable. The locking ring should be firm, but not tight. Connect
an IEC type mains cable with the plug fused at 13 AMPS, to the mains input socket on the DPS-4. Connect the other end to the
nearest plug socket and switch on the power to the DPS-4.

Linking DPS-4s
Two DPS-4 power supplies may be linked to provide continuing availability of power in the event that one of the supplies fails.
One of the supplies will feed the console via its “console” output socket. The two supplies can be connected to each other via their
“link” sockets.
Routine Maintenance
Routine maintenance is limited to cleaning the cooling fan’s air filter which is located on the front panel. Ensure that the DPS-4 is
switched off and unplugged before starting this procedure otherwise personal injury or damage to the fan blades may occur.
