1. PREPARATION
DANGER
: Electrical shock or burn hazard.
Installation of this device should only be made
by qualified personnel. Failure to lockout
electrical power during installation or maintenance can
result in fatal electrocution or severe burns. Before
making any connections be sure that power has been
removed from all associated wiring, electrical panels,
and other electrical equipment.
CAUTION NOTES
:
1. The installation of this device should follow all
applicable electrical codes, such as the National
Electrical Code.
2. Check to make sure line voltage does not exceed
DAR275V voltage ratings.
3. Follow all instructions to ensure correct and safe
operation.
4. Do not attempt to open or tamper with the DAR in
any way as this may compromise performance and
will void warranty. No user serviceable parts are
contained.
2. INTRODUCTION
Selected DSD, TDS & TDF DINLINE Surge Protection
Devices include status monitoring circuits which provide visual
status display of device capacity. They may also provide a low
voltage opto-coupler alarm output circuit that can be connect to
the DAR to provide potential free (Form C) change-over
contacts. The DAR alarm contacts may be used to provide
output to external alarm systems or remote monitoring circuits.
One DAR can be used per DSD/TDS/TDF opto-coupler alarm
or up to 16 DSD opto-coupler alarms can be connected in
series to the one DAR to provide a common output. It is
recommended that the DAR be powered from the same
power circuit that feeds the device(s) being monitored,
however the DAR can be powered from other circuits. This
allows for example, one DAR unit to be connected to separate
SPDs that are protecting a three phase circuit.
Note. Depending upon the usage of the DAR output contacts,
failure of power to the DAR may be interpreted as a failure of
one or more of the SPDs being monitored. Visual inspection
of the DAR and SPDs status displays would determine this.
3. MOUNTING
The DAR is designed to clip to 35mm (top hat) DIN rails
(standard EN50022). Unless otherwise mechanically
restrained, use horizontal DIN rails with the DAR module
spring clips to the bottom and the label text the correct way up.
NOTE:
The DAR must be installed in an enclosure or panel
that:
•
prevents the DAR temperature from exceeding
131°F (55°C)
• provides adequate electrical and safety protection
• prevents the ingress of moisture and water
• allows DAR status indicators to be inspected
4. ELECTRICAL CONNECTION
The interconnecting wiring should:
•
be of size #10 to #14 AWG (2.5mm² to 6mm²) solid or
stranded conductor.
•
The wire insulation should be stripped back 5/16" (8mm).
•
NOTE: Do not use greater than 9inlbs (1Nm) of torque
when tightening the terminals.
CONNECTION TO TELECOMMUNICATIONS NETWORKS
The DAR is approved for use in Australia where the alarm
contacts may be connected to private lines or building cabling
associated with the telecommunications network. NO direct
connection to the public switched network should be made.
