Seaward PAC 1500Xi - Manual (Page 9)

WARNING
a)
Do not touch the appliance while testing is in progress. A high voltage of 500V is
applied with respect to earth during the Insulation Test.
b) Ensure that the earth clip of the bonded earth test cable is securely attached to the
appliance. A poor connection may result in arcing of the contact.
c) If it is unclear which Class of insulation applies to the appliance being tested it is
recommended that the manufacturers operating instructions be consulted.
d) It is recommended that the PAC1500Xi is periodically checked by testing an
appliance of known electrical characteristics.
e) If the PAC1500Xi is used to conduct a series of Earth Bond tests the internal
circuitry will heat up. It is recommended that the PAC1500Xi is allowed to recover
for a short period between close sequences of tests.
f) If the PAC1500Xi does overheat a thermal trip will trigger removing the supply from
the unit. In this case the PAC1500Xi should be allowed to recover for a reasonable
period to allow the internal circuitry to cool. The thermal trip is only likely to trigger
in the event of an extended sequence of Earth Bond tests.
g) The PAC1500Xi contains a safety device which will trigger if the internal circuitry
fails causing the unit to power either the Insulation test or Earth Bond test circuitry
continuously. This can be reset by removing the power from the PAC1500Xi for a
few seconds and then reconnecting it. In normal use this should not arise thus in
the event of this occurance the unit should be returned for service.
MAINTENANCE
The PAC1500Xi is a rugged, quality instrument. However care should be taken in its
use, failure to do so will reduce the instrument’s life and hinder its reliability.
1) Always check all test leads for signs of damage prior to use.
2) Always check the PAC1500Xi for signs of damage prior to use.
3) Keep the PAC1500Xi clean and dry. If the instrument requires cleaning disconnect
from the mains supply and wipe clean using a cloth moistened with weak detergent
solution or a proprietary foam instrument cleaner.
4) Avoid testing in conditions of high electrostatic or electromagnetic fields.
5) No attempt should be made to gain access to the instrument whilst under test
conditions.
6) Maintenance should only be performed by authorised personnel.
The PAC1500Xi contains no user serviceable parts.
Should the PAC1500Xi require service, repair or calibration, return the equipment to a
recognised dealer or to;
