8. NON-STANDARD PRODUCTS
& ACCESSORIES
This document details the installation
procedure for our current range of standard
TSG-SRFs. Non-standard units are also
manufactured to suit specific customer
requirements. This manual is likely also to
be supplied with these units. The following
are details for some of the non-standard
variations and options available.
Backplane unit:
Normally denoted by ‘BP’ in the model
number. These units are supplied without
the proprietary enclosure and are intended
to be mounted in a customer provided
switchboard.
Low Voltage unit:
This is an alternative voltage version of
the standard TSG-SRF. This unit incorporates
primary and secondary surge diverters
specifically designed for low voltage
applications (110/120VAC).
Surge Counter:
Optional surge counter (available for the
TSG-SRF three-phase 125A to 2000A models).
Benefits of having the surge counter installed
are accurate and reliable monitoring of
surge activity and predictive maintenance
scheduling. Accidental erasure of the surge
count is prevented by the use of a
non-resetable counter display.
The surge counter can be either factory or
field installed. The ordering information for
this option is detailed below.
• Factory installed - Add the following
postscript to the part number of the
product. (TSG-SRF3125 /SC for a three-
phase 125A Surge Reduction Filter with
factory installed surge counter)
• Field installed - Order a TDS-SC from your
nearest ERICO ® office or distributor. When
installing the TDS-SC, please follow the
upgrade installation instructions which
are provided with the counter.
