Chapter 1
Introduction
A Tie Cabinet can be installed as a wall-mounted bypass or to provide support for a
parallel system for redundancy or extra capacity.
A wall-mounted bypass switch is used to bypass the UPS during maintenance or
servicing, providing wrap-around bypass for UPS service without shutting down the
load.
A parallel (load sharing) system provides more capacity than a single UPS and can
provide backup, depending on the load and configuration. In addition, when one UPS
is taken out of service for maintenance or is not operating properly, a redundant UPS
®
continues to supply uninterrupted power to the critical load. A parallel Powerware
Hot Sync Controller Area Network (CAN) Bridge Card provides connectivity for
®
system metering and operational mode control. The parallel system consists of two to
four UPSs, each with a parallel CAN Bridge Card and a parallel cabinet.
Figure 1 shows the Powerware 9355 UPS.

Safety Warnings
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that you should follow during installation and maintenance of
the UPS and batteries. Please read all instructions before operating the equipment and save this manual for
future reference.
DANGER
This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by AUTHORIZED

CONSIGNES DE SÉCURITÉ IMPORTANTES
CONSERVER CES INSTRUCTIONS
Ce manuel comporte des instructions importantes que vous êtes invité à suivre lors de toute procédure
d’installation et de maintenance des batteries et de l’onduleur. Veuillez consulter entièrement ces
instructions avant de faire fonctionner l’équipement et conserver ce manuel afin de pouvoir vous y reporter
ultérieurement.
DANGER!
Cet onduleur contient des TENSIONS MORTELLES. Toute opération d’entretien et de réparation doit être
EXCLUSIVEMENT CONFIÉE A UN PERSONNEL QUALIFIÉ AGRÉÉ. AUCUNE PIÈCE RÉPARABLE PAR
L’UTILISATEUR ne se trouve dans l’onduleur.
AVERTISSEMENT!
S Cette onduleur possède sa propre source d’alimentation (batteries). Il est possible que la sortie de
l’onduleur soit sous tension même lorsque l’onduleur n’est pas connectée à une alimentation CA.
S Pour réduire les risques d’incendie et de décharge électrique, installer l’onduleur uniquement à
l’intérieur, dans un lieu dépourvu de matériaux conducteurs, où la température et l’humidité ambiantes
sont contrôlées. La température ambiante ne doit pas dépasser 40 °C. Ne pas utiliser à proximité d’eau
ou dans une atmosphère excessivement humide (95 % maximum).
S Afin de réduire les risques d’incendie, n’effectuez le raccordement qu’avec un circuit muni d’une
protection de surintensité du circuit de dérivation maximum de 125 ampères conformément au Code
Électrique National (National Electrical Code) des États-Unis ANSI/NFPA 70.
S La protection de surintensité de sortie ainsi que le sectionneur doivent être fournis par des tiers.
ATTENTION!
S Les batteries peuvent présenter un risque de choc électrique ou de brûlure provenant d’un courant de
court-circuit haute intensité. Observez les précautions appropriées. L’entretien doit être réalisé par du
personnel qualifié connaissant bien les batteries et les précautions nécessaires. N’autorisez aucun
personnel non qualifié à manipuler les batteries.
S Une mise au rebut réglementaire des batteries est obligatoire. Consulter les règlements en vigueur dans
votre localité.
S Ne jamais jeter les batteries au feu. L’exposition aux flammes risque de les faire exploser.

Tie Cabinet Installation
The Powerware 9355 has the following power connections:
S 3-phase (L1, L2, and L3), neutral, and ground connection for rectifier/bypass input
S 3-phase (L1, L2, and L3), neutral, and ground connection for load output
The nominal input/output voltages are:
S 120/208 or 127/220 Vac
Output overcurrent protection and disconnect switch must be provided by others.
Figure 9 and Figure 11 beginning on page 15 show the oneline diagrams.
WARNING
Only qualified service personnel (such as a licensed electrician) should perform the UPS installation and
initial startup. Risk of electrical shock.
To hardwire the Tie Cabinet:
1. Verify that the electrical connections to the installation site have been properly
installed.
2. A wall-mounted, user-supplied, readily-accessible disconnection device must be
incorporated in the input wiring.
Compare the circuit breaker ratings to the ones in Table 1 on page 11.
NOTE To accommodate the feature of easy system expandability, it is recommended that initial installation
of the Powerware 9355 UPS contain wiring to support the maximum capacity of the UPS cabinet.
3. Switch off utility power to the distribution point where the Tie Cabinet and UPSs
will be connected. Be absolutely sure there is no power.
4. Determine your equipment’s grounding requirements according to your local
electrical code.

1 Use only 90°C-rated copper wire. Minimum wire size is based on 120/208 full load ratings applied to NEC Code Table 310-16. Code may require a larger
AWG size than shown in this table because of temperature, number of conductors in the conduit, or long service runs. Follow local requirements.
2 Per NEC article 300-20(a), all three-phase conductors must be run in the same conduit. Neutral and ground must be run in the same conduit as the
phase conductors.
3 Conduit is sized to accommodate one neutral conductor the same size as the phase conductor and one ground conductor. If two neutral conductors or
an oversized neutral conductor are to be installed, check the size of the conduit needed to accommodate the extra wire or size and use that conduit size
in place of the conduit size listed. Conduit sizes were chosen from NEC Table C1, type letters RHH, RHW, RHW-2, TW, THW, THHW, THW-2.

INSTALLING OPTIONS
11. Wire the pull-chain wiring to Signal Input 2 on each UPS and daisy chain the
wiring to each UPS as shown in Figure 18. Be sure to check correct polarity:
S Connect Pull-Chain Output Contact Pin 1 to Signal Input 2 Pin 1 on each UPS.
S Connect Pull-Chain Output Contact Pin 2 to Signal Input 2 Pin 2 on each UPS.
CAUTION
If polarity or wiring is not correct, the parallel system does not operate normally. For example, when shutting
