4.1 Installation
The product must only be installed by suitably qualified
personnel in accordance with the latest issues of the relevant
standards.
The installation of the units must also be in accordance with
any local codes that may apply and should only be carried out
by a competent electrical engineer who has the necessary
training.
The Enclosure is non-conducting and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the equipment
is not installed in a location where it may be subjected to
external conditions (such as high-pressure steam) which may
