3. Fitting and Installation
3.1 Precautions
•
Special conditions of use relating to the Ex
certification may apply to particular applications.
• The cable gland used with Free Plugs and Free
Receptacles must be an approved Ex d type
which is suitably certified for the equipment and
the type of cable to be used.
•
Gland entries must be fitted with suitable ingress
seals to maintain the overall ingress protection of
the connector.
• Ensure that the current and voltage parameters
of the electrical circuits are within the limits
specified.
• The sealing faces and flame paths will have
been treated with a protective film of grease
during manufacture. Renew if necessary before
assembly or engagement, in accordance with the
relevant installation standards and procedures.
• Ensure that the end cap screws are in place and
are fully tightened before engagement.
• Always fit either a rubber ingress protection cap
or an Ex protection cap to disengaged connectors
to protect flame paths and to exclude debris and
moisture.
•
Do not disengage the connector by pulling on the
cable as this may damage the fitting of the cable
into the cable gland.
• A connector with a damaged flame path is an
explosion risk and should be removed from
service.
