1.2 Options and Accessories
Contact your Eaton sales representative for information about the following options:
1.2.1 5% Input Filter
The UPS can be equipped with an input filter. An input filter yields power factor
correction that allows you to save on your initial installation and operating costs. The
filter also reduces input harmonic current distortion and minimizes upstream
interference that can damage sensitive hardware components.
1.2.2 Battery Racks
You can enhance the protection time provided by the UPS system by adding one or
more battery racks. The battery racks should be equipped with sealed,
maintenance‐free, lead‐acid batteries. An external battery disconnect switch must be
used. See Chapter 4, “Installing a Remote Battery Disconnect,” for additional
information.
1.2.3 External Fused Battery Disconnect
An optional external DC disconnect provides an automatic or manual means of
disconnecting a battery string from the UPS. The disconnect is enclosed in a
floor-mounted, free‐standing box. You can install it anywhere between the remote DC
supply and the UPS, according to national and local codes.
The breaker switch on the remote battery disconnect is set according to the operation
procedures in Chapter 9, “UPS Operating Instructions.” When service personnel are
performing maintenance on the UPS or battery string, the switch should be set to the
OFF position. See Chapter 4, “Installing a Remote Battery Disconnect,” for battery
disconnect requirements and installation instructions.
1.2.4 Upgrade Capability
The UPS is available in various output power ratings in both 50 and 60 Hz models. If
your power requirements increase, you can upgrade the UPS system to provide more
output power with a minimum impact on your facility.
1.2.5 Parallel Capacity/Redundant System
With Powerware Hot Sync ® technology and a System Bypass Module (SBM), the
Parallel Capacity/Redundant System allows two to eight uninterruptible power
modules (UPMs) to operate in parallel to provide more capacity than a single UPM
and as backup for each other. The parallel capacity/redundant system can supply up to
4000A, depending on the SBM used. In addition, when one UPM is taken out of
service for maintenance or is not operating properly, the redundant UPM continues to
supply uninterrupted power to the critical load.
