Installation, Assembly, and Setup
System Design
The PureWave SMS-250 Storage Management System can be
connected to 380 Vac directly or, using an auto transformer,
to 400, 415, or 480 Vac, 3-phase, 50/60 Hz (to match system
frequency), 380-Vac delta primary, 265 kVA.
The storage management system consists of a 263-kW/
263-kVA power converter housed in a weatherproof enclosure
suitable for outdoor or indoor mounting on a concrete or
equivalent pad, which can be applied either with or without
a 618- to 850-Vdc battery pack, depending on the application-
specific requirements. For specific applications that do not
require a battery pack, the PureWave SMS-250 assembly will
be supplied without the dc EMI filter, and dc bus terminations.
The PureWave SMS-250 system can use a modular design
capable of parallel operation to achieve a rating of up to
526 kW/ 526 kVA.
NOTICE
Utility interconnection may require approval from the
authority having jurisdiction .
Concrete Pad Specifications
NOTICE
The concrete pad is provided by others .
The concrete pad on which the PCS enclosure will be placed
should be sized to accommodate the unit and its external
mounting brackets. The pad should be poured with a
maximum pitch of
½
degree and should have a flatness within
⅛
inch (3.175 mm).
The pad should extend beyond the edge of the enclosure
by an adequate amount to prevent the pad from cracking
or breaking when the Hilti Kwik Bolt TZ anchor bolts are
installed to bolt the PCS enclosure to the pad.
