1. WARNINGS
• Prior to installation ensure that the unit is
of the correct voltage and frequency, and is
the type recommended for the local power
distribution, and for the equipment being
protected.
• Hazardous voltages may exist internally to
the modules. The units should be installed
(and replaced) only by qualified personnel
in accordance with all relevant Electricity
Safety Standards.
• Do not power three phase connected units
without the upstream neutral connected.
Failure to do so may damage the units and/
or the load.
• Where the unit has an earth terminal, this
must be connected to a low impedance earth
(<10
Ω) for correct operation.
• If connecting to the TDS Opto-coupler
alarm outputs do not reverse the +/-
connections or exceed the maximum
permissible ratings as damage may occur.
• Use only the TDS-AR Alarm Relay with
TDS-DINLINE.
• Use only TDS-SC Surge Counter with TDS
DINLINE.
• Units must be installed in an enclosure or
panel, ensure this does not cause the units
environmental ratings to be exceeded.
• Do not “Megger” or “Flash Test” circuits
with TDS-DINLINE units installed.
• All instructions must be followed to ensure
correct and safe operation.
• Diagrams are illustrative only, and should
not be relied on in isolation.
