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.
