Installation, Assembly, and Setup

S&C Instruction Sheet 659-525 13
Installation, Assembly, and Setup
Earth Reference and Bonding
Earth Reference Requirements:
A low-impedance earth reference connection is required
for the PureWave SMS-250 equipment. The earth (ground)
reference system should be tailored to reect the char-
acteristics of the site and the requirements of the facility
and shall use a grounding interface that meets the needs
of the local electric utility’s system and that complies with
all applicable national and local electrical codes and stan-
dards. The PureWave SMS-250 uses power converters that
switch at frequencies up to 5 kHz. For S&C PureWave SMS-
250 equipment and systems rated less than 1000 kVA, the
resistance of the SMS-250 earth reference connection to
earth is required to be 25 ohms or less at both the nominal
power frequency of 50 or 60 Hz, and at the 5-kHz switching
frequency of the SMS-250 power conversion system.
Any associated battery equipment must have its own
direct earth reference connection. It is not permitted to
only ground the battery equipment through the PureWave
SMS-250 earth reference connections.
Bonding Requirements:
Besides the importance of creating an earth reference,
bonding is required between interconnected electrical
equipment to establish a low impedance path that minimizes
the potential difference between two metallic objects,
minimizes electric shock hazards, provides lightning
protection, and establishes references for electronic signals.
All cable tray, conduit, and raceway systems installed to
interconnect power, control, and communications wiring to
and from the S&C PureWave SMS-250 shall be electrically
continuous by bonding together at each individual section.
Each individual cable tray, conduit, and raceway section,
including pull boxes, junction boxes, and outlet boxes,
shall be bonded to the facility earthing system within 2 feet
(600 mm) of each end and at intervals not exceeding
50 feet (15 meters) along the run. All cable trays, conduits,
and raceways shall be securely bonded to all brackets,
hangers, and structural members to which they are
attached. The resistance of each bonding connection
shall not exceed 5 milliohms. The total bonding resistance
between the PureWave SMS-250 cabinet and any battery
cabinet/enclosure shall be no more than 1 ohm.
Communications Signal
Reference Requirements
All communications systems that interface with the
PureWave SMS-250 equipment must be designed for
operation in a multipoint earth (ground) reference system.
See examples of ground plan diagrams in Figures 7 and 8.
