Electrical connections – heater
Lay the connector cables so that they cannot chafe. Also use
edge protection or leadthrough bushing on sharp edges, such
as holes on metal walls. The connector cables must not be
fixed to or touch metallic equipment surfaces, the exhaust
duct or the warm air ducts.
The electrical connection is made via an external cable
harness.
Take care with the connector cables so that they are not
pulled out or squashed.
