WARNINGS: Main disconnect is accomplished by disconnecting
the detachable power supply cord at the appliance coupler or
at the main plug. Ensure the power cord is easily accessible
and removable, in the event of an emergency, which requires
immediate disconnection.
The operator should check the detachable power supply cord
condition. The equipment should not be operated if the power
supply cord is cracked or broken. Any obvious damage to the
enclosure (from a drop or fall) should be checked by service
personnel for loose or damaged parts inside.
CAUTIONS: Replace the power cord only with one of the same
type and rating. The minimum power ratings are stated on the
rear panel.
The power cord set supplied with your pump drive meets the
requirements of the country where you purchased the pump
drive. If you use the pump drive in another country, you must use
a power cord set that meets the requirements of that country.
Keep the drive enclosure clean with mild detergents. Do not immerse or
use excessive fluid when cleaning.
