Electrical hazards
The pump must only be connected to power supplies which meet the
requirements for functional extra-low voltages with positive isolation in
accordance with IEC 364 (or local regulations) (SELV).
The OEM power supply unit must only be connected by qualified electrical
personnel.
Unplug any connectors only when the mains voltage is switched off
and
the pump does no longer turn (the green LED is off).
When the connector cable is attached, the outputs at the frequency con-
verter are not free of voltage.
Qualified personnel
Qualified electrical personnel in this instruction manual means a person who
has received electrical engineering instruction or is an electrical expert in
accordance with EN 60204, Part 1, 3.30 respectivly 3.55.
Thermal hazards
During operation the pump can become so hot that there is a danger of
burns (
≥
70
°
C, 158
°
F).
Provide protection against contact with the hot components.
Hazards caused by materials and substances
The forevacuum line must be tight. Hazardous gases can escape at leaks
or the gases being pumped can react with air or humidity.
If the pump has previously handled hazardous gases, implement the pro-
per precautionary measures before opening the intake or exhaust connec-
tion.
If necessary, use gloves, a respirator and/or protective clothing and work
under an exhaust hood.
Contaminated parts can be detrimental to health and environment. Before
beginning to work, find out whether any parts are contaminated. Adhere
to the relevant regulations and take the necessary precautions when
handling contaminated parts.
