DRAWMER

The CPA-50 unit will be supplied with a power cable suitable for domestic power

outlets in your country. For your own safety, it is important that you use this cable to

connect to the mains supply earth. The cable must not be tampered with or modified.

The power supply socket has an integral fuse drawer containing the power fuse of

the same value, to suit the mains voltage for which the unit has been supplied.

Removal of the drawer is only possible with the power cord removed. The fuse

should never blow under normal operation. If the fuse is suspected of having blown,

then a fault will have occurred and this fault condition should be inspected by a

qualified service engineer. When replacing the fuse, always comply with the Safety

Instructions.

If the unit is to be used with a mains input

operating voltage different to that for which

the unit is supplied, the following

procedure must be carried out by a

technically competent person:

1: Disconnect the unit from the mains

and cable.

2: Using a No.1 size pozidrive

screwdriver, remove the four screws

that retain the top cover.

For conversion to 230Volt AC

(previously set to 115Volt AC).....

3a. remove the j umper across the

CON101 socket

3b. Exchange the T800mA fuse below

the mains socket for a similar type

rated at T500mA

For conversion to 115Volt AC

(previously set to 230Volt AC).....

4a. Add a jumper across the CON101 socket

4b. Exchange the T500mA fuse below the mains

socket for a similar type rated at T800mA

In all cases:

5: Replace the top cover using the four screws.

6: Re-connect to mains power source.

PORTABLE APPLIANCE TESTING

To undergo a Portable Appliance Testing procedure (commonly known as "PAT",

"PAT Inspection" or "PAT Testing") remove the screw on the right side of the CPA-50,

nearest the IEC socket that holds the cover in place and probe in this cavity.

Alternatively, the screw can be replaced for something more suited to the job, such

as a spade terminal with a self tapping M3 thread.
