This instrument is a Safety Class 1 product and therefore must be earthed. Use the
supplied power cord or an appropriate replacement. Make sure the instrument is plugged into an
outlet socket with a protective earth contact.

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 is required.
Whichever is the disconnecting device, make sure it can be easily reached by the operator and
that it is accessible at all times.

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 moulded 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. Please check
with your local sales office for availability.

CONNECTING TO AC SUPPLY

Before connecting the instrument to the AC supply, check the position of the voltage
selector switch. The range selected can be seen on the side of the switch protection plate situated
on the rear panel.

The instrument is normally dispatched selected to the 210-240 V range. To select the
105-120 V range remove the protection plate, switch ranges and change the value of the AC
supply fuses to that shown below, reverse and refit the protection plate.

Fuses are 20 mm x 5 mm cartridge type.

115 V range: T500mAL250V
230 V range: T250mAL250V

ROUTINE SAFETY TESTING AND INSPECTION

In the UK, the ‘Electricity at Work Regulations’ (1989) section 4(2) places a requirement
on the users of equipment to maintain it in a safe condition. The explanatory notes call for
regular inspections and tests together with a need to keep records.

The following electrical tests and inspection information is provided for guidance
purposes and involves the use of voltages and currents that can cause injury. It is important that
these tests are only performed by competent personnel.

Prior to carrying out any inspection and tests, the instruments must be disconnected from
the mains supply and all external signal connections removed. All tests should include the
instrument’s own supply lead, all covers must be fitted and the equipment supply switch must be
in the ‘ON’ position.

INSTALLATION

The recommended inspection and tests fall into three categories and should be carried out

in the following sequence:-

1. Visual inspection

2. Earth bonding tests

3. Insulation resistance test

1. Visual inspection

A visual inspection should be carried out on a periodic basis. This interval is dependent
on the operating environment, maintenance and use, and should be assessed in accordance with
guidelines issued by the Health and Safety Executive (HSE). As a guide, this instrument when
used indoors in a relatively clean environment would be classified as ‘low risk’ equipment and
hence should be subject to safety inspections on an annual basis. If the use of the equipment is
contrary to the conditions specified, you should review the safety re-test interval.

As a guide, the visual inspection should include the following where appropriate:

Check that the equipment has been installed in accordance with the instructions provided
(e.g. that ventilation is adequate, supply isolators are accessible, supply wiring is adequate and
properly routed).

The condition of the mains supply lead and supply connector(s).

Check that the mains supply switch isolates the instrument from the supply.

The correct rating and type of supply fuses.

Security and condition of covers and handles.

Check the supply indicator functions (if fitted).

Check the presence and condition of all warning labels and markings and supplied safety

information.

Check the wiring in re-wireable plugs and appliance connectors.

If any defect is noted this should be rectified before proceeding with the following

electrical tests.

2. Earth bonding tests

Earth bonding tests should be carried out using a 25 A (12 V maximum open circuit
voltage) DC source. Tests should be limited to a maximum duration of 5 seconds and have a
pass limit of 0.1 Ω after allowing for the resistance of the supply lead. Exceeding the test
duration can cause damage to the equipment. The tests should be carried out between the supply
earth and exposed case metalwork, no attempt should be made to perform the tests on functional
earths (e.g. signal carrying connector shells or screen connections) as this will result in damage to
the equipment.

3. Insulation tests

A 500 V DC test should be applied between the protective earth connection and combined
live and neutral supply connections with the equipment supply switch in the ‘on’ position. It is
advisable to make the live/neutral link on the appliance tester or its connector to avoid the
possibility of returning the equipment to the user with the live and neutral poles linked with an
ad-hoc strap. The test voltage should be applied for 5 seconds before taking the measurement.

Aeroflex employs reinforced insulation in the construction of its products and hence a
minimum pass limit of 7 MW should be achieved during this test.

Where a DC power adapter is provided with the equipment, the adapter must pass the
7 MΩ test limit.

INSTALLATION

We do not recommend dielectric flash testing during routine safety tests. Most portable
appliance testers use AC for the dielectric strength test which can cause damage to the supply
input filter capacitors.

4. Rectification

It is recommended that the results of the above tests are recorded and checked during each
repeat test. Significant differences between the previous readings and measured values should be
investigated.

If any failure is detected during the above visual inspection or tests, the equipment should
be disabled and the fault should be rectified by an experienced Service Engineer who is familiar
with the hazards involved in carrying out such repairs.

Safety critical components should only be replaced with equivalent parts, using
techniques and procedures recommended by Aeroflex.

The above information is provided for guidance only. aeroflex designs and constructs its
products in accordance with International Safety Standards such that in normal use they represent
no hazard to the operator. Aeroflex reserves the right to amend the above information in the
course of its continuing commitment to product safety.

Cleaning

Before commencing any cleaning, switch off the instrument and disconnect it from the
supply. The exterior surface of the case may be cleaned using a soft cloth moistened in water.
Do not use aerosol or liquid solvent cleaners.

Cleaning the LCD Window

To prevent damage to the LCD window, care should be taken not to scratch the surface
during use and also when cleaning. The LCD window should be cleaned by wiping a slightly
damp, soft, lint-free cloth gently over the surface. To remove grease or smears, use a clean
cotton cloth moistened with Heptane. No other cleaning agents should be used. Clean the
window using either horizontal or vertical strokes, NEVER a circular action.

GPIB INTERFACE

The GPIB interface module is available as an optional accessory (no. 03964-650E). This
consists of a kit of parts, complete with fitting instructions.

RACK MOUNTING KITS

(1) For rack mounting the 6960B on its own, a single unit rack mounting kit (no.

46884-500K) is available. This contains a pair of side angle plates wide enough to
allow the instrument o sit centrally within the rack frame.

(2) For rack mounting the 6960B on its own, a single unit rack mounting kit (no.

46884-501A) is available. This kit contains fixings for joining the two instruments
together and for attaching the twinned unit to the rack. A blanking plate is also
supplied for one half of the kit, allowing the 6960B to be mounted alone while
retaining the option of mounting a second instrument beside it.

(3) Rack mounting instructions are supplied with the kits.
