LEYBOLD SCROLLVAC plus - Thermal Hazards; ATEX Directive Implications

WARNING: HAZARDOUS VOLTAGE
Risk of injury or damage to equipment and risk of electric shock. Operator must
wait for a minute for capacitor discharge after disconnecting the power supply
before working on the pump.
▪
Make sure that the electrical installation of the pumping system▪
conforms with your local and national safety requirements. It must be
connected to a suitably fused and protected electrical supply and a
suitable earth (ground) point.
▪ This equipment is suitable for Installation Category II as dened in▪
IEC60664-1. The dry pumping system must be connected to an
isolator that disconnects all current carrying conductors and can be
locked in the off position (LOTO). The isolator must be in close proximity
to the equipment, within easy reach of the operator and identied as the
disconnect device for the equipment.
▪ Isolate the electrical supply before disconnecting the electrical supply▪
cable from the dry pumping system.
▪ Make sure that the system and your electrical supply cable are suitably▪
protected against earth (ground) faults and that the earth (ground)
conductor of the electrical supply cable is longer than the phase
conductors in the connector.
▪ The power wiring to the system must be properly protected and routed▪
away from any potential hazards.
2.3Thermal hazards
WARNING: HOT SURFACE
Risk of burns. Do not touch the pump inlet or exhaust ports while the pump is
running since the temperature of these parts could be high enough to cause harm.
Elevated temperature could remain after the pump has stopped.
▪ Care shall be taken during nal installation to make sure that access to▪
hot surfaces are prevented by additional guarding.
▪ Do not exceed the maximum continuous operating pressures (COP)▪

2.4ATEX directive implications
Pumps which carry the ATEX mark are designed to meet the requirements
of Group II Category 3G in respects to ignition sources internal to the pump.
This classication is in accordance with Directive 2014/34/EU.
There is no potential source of ignition within the pump during normal
operation but there may be potential sources of ignition under conditions
of rare or unexpected malfunction as dened in the directive. As a result
of this, it is necessary to consider the potential consequences of ignition
