Wayne 4310 - AC Power Supply; Adjustment, Maintenance and Repair

Safety 1–2
1.2 AC Power Supply
Power cable and connector requirements vary between countries. Always use a cable that
conforms to local regulations, terminated in an IEC320 connector at the instrument end.
If it is necessary to fit a suitable AC power plug to the power cable, the user must observe the
following colour codes:
WIRE EUROPEAN N. AMERICAN
LIVE BROWN BLACK
NEUTRAL BLUE WHITE
GROUND GREEN/YELLOW GREEN
The user must also ensure that the protective ground lead would be the last to break should the
cable be subject to excessive strain.
If the plug is fused, a 3-amp fuse should be fitted.
If the power cable electrical connection to the AC power plug is through screw terminals then,
to ensure reliable connections, any solder tinning of the cable wires must be removed before
fitting the plug.
Before switching on the equipment, ensure that it is set to the voltage of the local AC power
supply.
WARNING!
Any interruption of the protective ground conductor inside or outside the equipment or
disconnection of the protective ground terminal is likely to make the equipment
dangerous. Intentional interruption is prohibited.
1.3 Adjustment, Maintenance and Repair
WARNING!
The equipment must be disconnected from all voltage sources before it is opened for any
adjustment, replacement, maintenance, or repair.
When the equipment is connected to the local AC power supply, internal terminals may be live
and the opening of the covers or removal of parts (except those to which access can be gained
by hand) is likely to expose live parts.
Capacitors inside the equipment may still be charged even if the equipment has been
disconnected from all voltage sources.
