Standard Accessories

Mounting hardware: Two removable flanges with M4 screws.
Outlet retention clips (208-240V models).
Additional items for Cx-xxx-C20 models:
Separate power input cords.
Power input retention bracket hardware (may be installed):

Safety Precautions

This section contains important safety and regulatory information that should be reviewed before installing and using the Sentry Rack-Mount Fail-Safe Transfer Switch. For input and output current ratings, see
Only for installation and use in a Service Access Location in accordance with the following installation and use instructions.
This equipment is designed to be installed on a dedicated circuit.
Dedicated circuit must have circuit breaker or fuse protection. CDUs have been designed without a master circuit breaker or fuse to avoid becoming a single point of failure. It is the customer’s responsibility to provide adequate protection for the dedicated power circuit. Protection of capacity equal to the current rating of the CDU must be provided and must meet all applicable codes and regulations. In North American, protection must have a 10,000A interrupt capacity.
The plug on the power supply cord shall be installed near the equipment and shall be easily accessible.
Always disconnect the power supply cords before opening to avoid electrical shock.
WARNING! High leakage current! Earth connection is essential before connecting supply!
WARNING! Cx-xxE-x units Double Pole/Neutral Fusing
Power Ratings in Appendix A: Technical Specifications.
Destiné à l'installation et l'utilisation dans le cadre de Service Access Location selon les instructions d'installation et d'utilisation.
Cet équipement est conçu à être installé sur un circuit spécialisé.
Le circuit spécialisé doit avoir un disjoncteur ou une protection de fusible. CDUs ont été conçus sans disjoncteur général ni fusible pour éviter que cela devient un seul endroit de panne. C’est la responsabilité du client de fournir une protection adéquate pour le circuit-alimentation spécialisé. Protection de capacité équivalant à la puissance de l'équipement, et respectant tous les codes et normes applicables. Les disjoncteurs ou fusibles destinés à l'installation en Amérique du Nord doivent avoir une capacité d'interruption de 10.000 A.
La prise sur le cordon d’alimentation sera installée près de l’équipement et sera facilement disponible.
Toujours déconnecter le cordon d’alimentation avant d’ouvrir pour éviter un choque électrique.
ATTENTION ! Haut fuite très possible ! Une connection de masse est essentielle avant de connecter l’alimentation !
ATTENTION! Les unités Cx-xxE-x Double Pôle/Fusible sur le Neutre
Nur für Installation und Gebrauch an Anschlusszugriffspunkten gemäß der folgenden Installations- und Gebrauchsanweisungen.
Diese Ausrüstung ist zur Installation in einem festen Stromkreis vorgesehen.
Der feste Stromkreis muss mit einem Schutzschalter oder einem Sicherungsschutz versehen sein. CDUs verfügt über keinen Hauptschutzschalter bzw. über keine Sicherung, damit kein einzelner Fehlerpunkt entstehen kann. Der Kunde ist dafür verantwortlich, den Stromkreis sachgemäß zu schützen. Der Kapazitätsschutz entspricht der aktuellen Stromstärke der Geräte und muss alle relevanten Codes und Bestimmungen erfüllen. Für Installation in Nordamerika müssen Ausschalter bzw. Sicherung über 10.000 A Unterbrechungskapazität verfügen.
Der Stecker des Netzkabels muss in der Nähe der Ausrüstung installiert werden und leicht zugänglich sein.
Ziehen Sie vor dem Öffnen immer das Netzkabel heraus, um die Gefahr eines elektrischen Schlags zu vermeiden.
ACHTUNG! Hoher Ableitstrom! Ein Erdungsanschluss ist vor dem Einschalten der Stromzufuhr erforderlich!
ACHTUNG!: Cx-xxE-x Zweipolige bzw. Neutralleiter-Sicherung

Installing the Power Input Retention Bracket

For units with a total maximum output <30A, it may be necessary to install the power input retention bracket prior to mounting the unit within the rack.

To install the power input retention bracket:

1. Remove the two screws attaching the IEC 60320 C19 inlet
to the enclosure.
2. Assemble and attach the retention bracket to the enclosure
as shown.

Mounting

1. Select the appropriate bracket mounting points for
proper mounting depth within the rack.
2. Attach the brackets to these mounting points with two
screws for each bracket.
3. Install the enclosure into your rack, using the slots in
each bracket. The slots allow about ¼ inch of horizontal adaptability to align with the mounting holes of your rack.
NOTE: A mounting bracket kit for 23” wide racks or cabinets is available. Contact your Server Technology Sales Representative for more information.
Figure 2.1 Retention Bracket assembly
Figure 2. Mounting

Optimizing the Transfer Thresholds

The Voltage Selector switch is used to optimize the transfer threshold by configuring the Transfer Switch for the nominal operational voltage of the installation. The Transfer Switch uses this setting to
calculate the brownout and over-voltage threshold (± 13% ).
To optimize the transfer threshold:
Select the voltage setting that most closely matches the nominal operating voltage of the power sources.

Connecting to the Power Source

To attach a power cord to the unit:
1. Plug the female end of the power cord firmly into its connector at the base.
2. Use a screwdriver to tighten the two screws on the retention bracket.
To connect to the power source:
Plug the male end of the power cord into the AC power source.

Connecting Devices

1. Keep the device’s on/off switch in the off position until after it is plugged into the outlet.
2. Connect devices to the CDU outlets.
NOTE: Server Technology recommends even distribution of attached devices across all available outlets to avoid exceeding the outlet, branch or phase limitations. See Power Ratings on page 9 for more information.
Always disconnect ALL power supply cords before opening to avoid electrical shock. Afin d’éviter les chocs électriques, débranchez TOUTES les cables électrique avant d’ouvrir. Immer ALLE Netzleitungen auskuppeln vor den Aufmachen um elektrischen Schlag zu vermeiden.

Chapter 3: Operations

Modes of Operation

The Sentry Rack-Mount Fail-Safe Transfer Switch is designed to operate in the following modes:
Normal
Infeed A provides power to branches A1 & A2 and Infeed B provides power to branches B1 & B2. Each infeed is monitored individually for voltage and current.
Input Failure
The equipment powered by the failed input is transferred to the remaining input. The input current LED display of the failed input will be blank and the remaining display will report the total current load for the unit.
Recovery from Input Failure
When voltage is restored to the failed input and remains within ±7% of nominal for 2 seconds, the
equipment normally supported by that input is transferred back returning the Sentry to a ‘Normal’ mode with the input current LED displays reporting the total current load for each respective infeed.
Brownout/Over-Voltage
When an input’s voltage varies from its nominal by ±13% or more, the equipment powered by that
input is transferred to the remaining input. The input current LED display of the input in the brownout/over-voltage state will be blank and the remaining display will report the total current load for the unit.
Nominal Voltage* Brownout Recovery Voltage Over-Voltage
100V 87.0V 93.0V 107.0V 113.0V 110V 95.7V 102.3V 117.7V 124.3V 115V 100.0V 106.9V 123.0V 129.9V 120V 104.4V 111.6V 128.4V 135.6V 208V 181.0V 193.4V 222.6V 235.0V 220V 191.4V 204.6V 235.4V 248.6V 230V 200.1V 213.9V 246.1V 259.9V 240V 208.8V 223.2V 256.8V 271.2V
*
Nominal operating voltage is configured by the Voltage Selector Switch.
Recovery from Brownout/Over-Voltage
When the input’s voltage returns to and remains within ±7% of nominal for 2 seconds, the
equipment normally supported by that input is transferred back returning the Sentry to a ‘Normal’ mode input current LED displays reporting the total current load for each respective infeed.
Critical Brownout
A critical brownout is when an input’s voltage drops below its nominal by -25%.
When an input is already in a brownout/over-voltage state AND the remaining input
experiences a critical brownout, ALL equipment will be transferred to the input only experiencing a brownout/over-voltage.
When an input has already failed AND the remaining input experiences a critical
brownout, ALL outlets will turn off.
Recovery from Critical Brownout
When the input’s voltage returns to and remains within ±7% of nominal for 2 seconds, the
equipment normally supported by that input is transferred back.
