SAFETY/WARNING PRECAUSTIONS
To ensure that the device can be operated
safely and all functions can be used, please read
these instructions carefully.
Installation and Start-up must be carried out by
qualified personnel only. The relevant county-
specific regulations must also be observed.
Before start-up it is particularly important to
ensure:
 Terminal wiring: check that all cables are
correctly connected according to the connection
diagram
 All wiring must confirm to appropriate
standards of good practice and local codes and
regulations. Wiring must be suitable for voltage,
current and temperature rating of the system.
 Unused control terminals should not be used
as jumper points as they may be internally
connected, which may cause damage to the
unit.
