INSTALLATION
2.1. INITIAL INSPECTION
This instrument was carefully inspected both mechanically and electrically before
shipment. It should be free of marks and scratches and in perfect electrical order upon
receipt.
Unpack the instrument and retain the shipping container until the instrument has been
inspected for damage in shipment. If in-shipment damage is observed, notify the carrier
and obtain authorization for repairs before returning the instrument to the factory.
2.2. POWER REQUIREMENTS
The instrument is shipped with a three-wire line cord and must be connected to a
grounded 50 to 60 Hz ac power source. This product will operate at between 100 V and
240 V all
±
10 %.
WARNING: BEFORE SWITCHING ON THIS INSTRUMENT, THE
PROTECTIVE TERMINAL OF THIS INSTRUMENT MUST BE CONNECTED
TO A PROTECTIVE EARTH CONTACT. THE POWER LINE CORD
SUPPLIED WILL PROVIDE THE PROTECTIVE GROUNDING WHEN
INSERTED INTO A SOCKET OUTLET PROVIDED WITH AN EARTH
CONTACT. THE PROTECTIVE ACTION MUST NOT BE NEGATED BY THE
USE OF AN EXTENSION CORD OR ADAPTOR WITHOUT A PROTECTIVE
GROUNDING CONDUCTOR.
2.3. LOCATION
To ensure optimum performance, the Precision Voltage Divider should be installed in an
area having reasonably constant temperature, no strong electrostatic or magnetic fields,
and a minimum amount of vibration. The unit should not be located near heating or
cooling vents or in direct sunlight. Such locations can cause sudden temperature changes
resulting in generation of errors in the measurements due to thermal effects.
WARNING: NEVER CHANGE OR ENGAGE A VOTAGE DIVIDER MODE OF
OPERATION WHILE LIVE VOLTAGE IS PRESENT. DOING SO CAN
DAMAGE THE VOLTAGE DIVIDER, OTHER CONNECTED EQUIPMENT
AND POSSIBLY RESULT IN INJURY OR DEATH. THE VOLTAGE DIVIDE
CAN BE OPERATED UP TO 1100V AND THEREFORE LEATHAL VOLTAGES
MAY BE PRESENT ON INPUT TERMINALS OR EVEN OUTPUT TERMINALS
IF USED INCORRECTLY.
