2 Important safety instructions
2.1
Wiring and Installation
The following safety instructions apply to all EU member states and should be followed
according to Low Voltage Directive. It is recommended that non-EU areas should also comply
with these instructions unless superseded by other local or national standards.
‒
It is essential that suitable grounding connections be made at all connectors provided for
this purpose.
‒
All safety covers and grounding connections must be properly reinstated after maintenance
or troubleshooting. The integrity of all earth terminals must always be maintained.
‒
To ensure safe operation of this equipment, connection to the mains supply should be made
through a circuit breaker which will disconnect all circuits carrying conductors in the case
of a fault. These circuit breakers should comply with a recognised standard such as
IEC947. All wiring must conform to any local or national standards.
2.2
Handling and Storing Pressurised Gases
This instrument requires pressurised gases for use. Some general safety precautions are
outlined below; however, it is advisable that operators are properly trained in the handling and
storage of pressurised gas containers:
‒
Never drop cylinders or permit them to strike each other violently.
‒
Cylinders may be stored in the open, but in such cases should be protected against
extremes of weather and, to prevent rusting, from the dampness of the ground. Cylinders
should be stored in the shade when located in areas where extreme temperatures are likely.
‒
The valve protection cap should be left on each cylinder until it has been safely secured
against a wall or other solid structure or placed is dedicated cylinder stand.
‒
Avoid dragging, rolling or sliding cylinders, even for a short distance
–
they should be
moved using a suitable transportation device (e.g. bottle trolley).
‒
Never tamper with the safety devices in valves or cylinders.
‒
Avoid storage of full and empty cylinders together. Serious suck-back can occur when
empty cylinders are attached to pressurised systems.
‒
No part of a cylinder should be exposed to a temperature higher than 52°C (125°F), or a
naked flame or incandescent material.
‒
Do not place cylinders where they could become part of an electric circuit.
