Aeroflex 2944B - Class I Power Cords

INSTALLATION
2-4
Class I power cords (3-core)
Disconnecting device
The detachable power cord is the instrument’s disconnecting device, but if the instrument is
integrated into a rack or system, an external power switch or circuit breaker may be required.
Whatever the disconnecting device, make sure that you can reach it easily and that it is accessible
at all times.
General
The instrument is a Safety Class 1 product and therefore must be earthed. Use the supplied power
cord or an appropriate replacement. Make sure that the instrument is plugged into an outlet socket
with a protective earth contact.
When the equipment has to be plugged into a Class II (ungrounded) 2-terminal socket outlet, the
cable should either be fitted with a 3-pin Class I plug and used in conjunction with an adapter
incorporating a ground wire, or be fitted with a Class II plug with an integral ground wire. The
ground wire must be securely fastened to ground. Grounding one terminal on a 2-terminal socket
will not provide adequate protection.
In the event that a molded plug has to be removed from a lead, it must be disposed of immediately.
A plug with bare flexible cords is hazardous if engaged in a live socket outlet.
Power cords with the following terminations are available from Aeroflex Ltd. Please check with
your local sales office for availability.
This equipment is provided with a 3-wire (grounded) cordset which includes a molded
IEC 60320-1 connector for connection to the equipment. The cable must be fitted with an
approved plug which, when plugged into an appropriate 3-terminal socket outlet, grounds the case
of the equipment. Failure to ground the equipment may expose the operator to hazardous voltage
levels. Depending upon the destination country, the color coding of the wires will differ:-
British
The UK lead is fitted with an ASTA approved molded plug to BS 1363.
A replaceable 13 A fuse to BS 1362 is contained within the plug. This
fuse is only designed to protect the lead assembly. Never use the plug
with the detachable fuse cover omitted or if the cover is damaged.
The fuse(s) or circuit breaker to protect the equipment is fitted at the back of the equipment.
North American
The North American lead is fitted with a NEMA 5-15P (Canadian
CS22.2 No 42) plug and carries approvals from UL and CSA for use in
the USA and Canada.
