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:
Auxiliary Power
 Terminal wiring: check that all cables are
Supply
correctly connected according to the connection
J diagram
85-265 VAC /
U1
 All wiring
K 100-300 VDC
standards of good practice and local codes and
T U2 18-36 VDC
regulations. Wiring must be suitable for voltage,
R
current and temperature rating of the system.
S
 Unused control terminals should not be used
as jumper points as they may be internally
connected, which may cause damage to the
unit.
