4.3. Connections

4.3.1. Mains connection

WARNING!
Potential risk of electric shock.

The device is a protective class 1 unit. A missing earth (ground)

contact may cause dangerous voltages in the housing and controls

and may lead to electric shock.
–

Connect the unit to mains power supplies with protective earth

only.

–

If there is any sign of obvious damage to the power cord

and/or mains connector, do not use the power cord and

replace it before further use.

–

Please ensure the mains connector is accessible at any time to

disconnect the unit in case of malfunction or danger.

If the mains plug is not readily accessible due to mounting in a

19" rack, then the mains plug for the entire rack must be

readily accessible.

–

Do not connect or disconnect the powerCON

mains

connector under load or live.
