ADDITIONAL INFORMATION FOR THE SAFE OPERATION OF THE CP65

To ensure proper operation and guard against potential shock hazard, the CP65 must be connected only to a properly wired, grounded (earthed) mains receptacle. If you are uncertain about the wiring of your mains outlet do not use it. Consult a qualified electrician. The power cord is supplied with either a standard U.S.A. three-prong plug or with unterminated leads for use in other countries. The wires are colored in accordance with the following international code:

	International	U.S.
live or hot	brown	black
neutral	blue	white
earth	green/yellow	green/yellow

Before the power cord is connected to the CP65, ensure that a qualified electrician has wired the cord following the code.

U.S. Style Plugs

The ground terminal of the plug is connected directly to the chassis of the unit. For continued protection against electric shock, a three-pin power receptacle MUST be used, and the ground wire MUST always be connected. DO NOT use a ground-lifting adaptor and NEVER cut the ground pin on a three-prong plug.

Connections for United Kingdom

WARNING: THIS APPARATUS MUST BE EARTHED.

As the colours of the cores in the mains lead may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:

-the core 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 , or coloured green or green and yellow.

-the core which is coloured blue must be connected to the terminal which is marked with the letter N or coloured black.

-the core which is coloured brown must be connected to the terminal which is marked with the letter L or coloured red.

WARNING—Before you connect the unit to mains power, check that it has been set to the correct mains voltage and that the correct fuse is installed. To reduce the risk of fire, replace the fuse only with the same type and 250V rating:

Voltage Setting	Fuse	Type
100/120/140 VAC	1.25 A	1/4" x 1-1/4" slow-blow
200/220/240 VAC	T 630 mA	5 x 20mm time lag.
