3.4 Reference Relative Humidity
The standard reference condition for relative humidity is 30%. Above this value the rated power must
be reduced.
3.5 Reference Barometric Pressure
The standard reference condition for total barometric pressure is 1 bar.
This corresponds to an altitude of approximately 100m. Above 100m the rated power must be
reduced.
3.6 Flammable Environment
Stephill Generators must not be used in a flammable environment.
3.7 Saline Environment
Operation of the machine in a saline environment will require additional corrosion protection.
4 SAFETY CONSIDERATIONS
4.1 General
All Stephill Generators comply with all the current EEC directives including:
2006/42/EC Machinery Directive
2000/14/EC Noise Emission in the Environment by Equipment for use Outdoors
2014/30/EU EMC Directive
2014/35/EU Low Voltage Directive
4.2 Fuel
Fuels and lubricants are a potential source of fire. Be careful not to spill fuel, clean up any spillages.
Inhalation or swallowing of Diesel should be avoided. If in doubt seek medical advice. All other forms
of contact are irritant and therefore should also be avoided. If skin contact is made wash with soap
and water.
4.3 Bunded tank
This generator is fitted with a secondary containment system (Bunded tank). The bund will need to be
inspected on a regular basis and drained accordingly. Any liquid drained from the Bund/Tank will
have to be treated as Oil/Fuel contaminated waste and disposed of accordingly.
Warning
Although this generator is fitted with a Bunded tank it is the duty of the owner to ensure that it meets
with Local/National regulations dependant on site location etc.
4.4 Lubricating Oil
New oil presents no hazard following short term exposure. Lubricants in particular used engine oil,
are potentially carcinogenic. Direct contact should always be avoided by wearing suitable rubber
gloves when handling them. Used oil should not be allowed to contact the skin. If this does occur,
wash off quickly with a proprietary hand cleanser.
4.5 Safe Lifting
Where mechanical assistance is used in lifting machines, ensure the lifting eye is used, and that all
components used to lift the machine are within their Safe Working Load (SWL).
The integral lifting beam and associated lifting eye on the generator should be regularly checked for
signs of damage or gross corrosion.
All Nuts and Bolts associated with the lifting beam should be regularly checked for tightness and
corrosion. Lifting equipment should not be attached directly to the Engine/Alternator except for lifting
of Engine/Alternator only.
4.6 Earth connection
All Stephill products are fitted with an earth stud on the control panel this must be connected to an
earthing system or spike. Any earth spike required is dependant on the local conditions of use. The
size is determined by reference to current IEE regulations or to a competent electrician.
4.7 Fumes
Make sure that the Generator is at least 2 metres away from any building during operation. Operate
in a well ventilated unconfined area, so that fumes can be properly dispersed. Silencer outlet should
