Be careful when removing the fasteners. Failure to replace all correctly prior
to use shall invalidate the certification.
•
Before the installation starts it is advised that the product is checked to ensure the
insulation resistance reading is above 2MΩ
for the heater when tested at no less
than 500 volts dc. To do this, connect the neutral cable (generally black) to any part
of the steel enclosure, connect the live (generally red) cable to any power terminal
and test for a minimum of 30 seconds.
•
Should the product fail this test, please contact the technical help via our website:
www.exheat-industrial.com/contact/support
•
Before connecting any supply cables, ensure that the incoming power supply
conforms to the specified voltage on the products nameplate at a nominal variance of
+/- 5% of the specified voltage.
Compliance with these instructions is a warranty requirement. Documented
evidence must be maintained in the form of a signed checklist. Copies of
completed checklists and records will be required in the event of any warranty
claim.
CAUTION – Check the voltage and current of the heater to ensure it is
compatible with the ratings of the supply before energising.
