EATON 777387 Relay MS Card

USING THE CARD WITH A SINGLE-PHASE UPS

INTRODUCTION

The Relay Card – MS offers two types of interfaces via a DB9 connector:

Dry contacts (contact mode)
RS232 serial interface (RS232 mode)

All UPSs from EATON equipped with a Mini slot can be connected to a number of electrical-management applications. Jumpers are used to select the interface (contacts or RS232).

APPLICATIONS

Contact mode (factory setting)

In this mode, the card provides a simple way to remote UPS information to an alarm system, PLC, or computer system via dry contacts (relay).
The transmitted information is load powered, load on bypass, load on the battery, load on utility, battery fault, and low battery.
A UPS power-off function activated by an external contact or voltage level is also proposed. It is available only in contact mode.
Equipped with an IBM iSeries or Windows cable available from EATON, the card offers direct communication with the power management system of the servers supplied by the UPS and can thus provide protection (shutdown) on the reception of one of the information signals. Configuration of the various systems is presented in the documents supplied with the cable. For this application, use the Config2 setting on the card.

RS232 mode

In this mode, the card offers an RS232 interface for connection to a PC. Connection to a PC requires the RS232 UPS Communication Cable. The cable is not supplied with the card. Once connected the protection software can be installed and used immediately.
The WindowsTM Plug&Play function is managed by the card.
The cable is available from EATON.

OVERVIEW

CONTACT MODE CONFIGURATION

In this mode, the contact (relay) is closed between the common (pin 5) and the pin transmitting the signal (pin 2, 4, 6, 7, 8, 9) when UPS information is active or true.
When the card is not supplied, all the contacts between pin 5 and the other pins are open, except the contact between pin 4 and pin 5, which remains closed.
Three configurations are available in this mode, for three types of UPS power off. The diagram below shows, for each configuration, the jumper settings, the various contacts (card not supplied), and the external wiring for the power-off function. The UPS shuts off if the contact position is the opposite of that shown.

DB9 CONNECTOR PINOUTS

No.	Function	Description
1	Not used
2*	Battery fault (Config 2) UPS power off (Config 1 or 3)	Config 2: a battery fault occurred. Config 1 or 3: UPS power off by contact.
3	UPS power off (Config 2) Not used (Config 1 or 3)	Config 2: UPS power off by voltage level.
4	Load on utility**	The load is protected. The UPS supplies the load using utility power (not from the battery).
5	Common	Config 2: volt-free pin. Config 1 or 3: pin connected to GND.
6	Load on automatic bypass***	The load is not protected. The UPS supplies the load using utility power. If utility power fails, the load will not be supplied.
7	Low battery	The battery has dropped below the preset warning level (depending on UPS setup). If the voltage level continues to drop, the UPS will no longer be capable of supplying power to the load.
8	UPS ON, load powered	The UPS is operational and can supply power to the load, whether utility power is available or not, whether the UPS is on the bypass or not.
9	Load on battery **	The load is protected. The UPS supplies the load from the battery (not using utility power).

The function of this pain varies, depending on the configuration. The Battery fault information is available only in Config 2.

Load on utility and Load on the battery are complementary signals. They cannot be activated simultaneously.
Not available online-interactive UPS. No manual bypass.

RS232 MODE CONFIGURATION

In this mode, only one configuration is possible

INSTALLATION

The Relay Card – MS can be installed on a running UPS from EATON compatible with this card. It is not necessary to shut off the UPS, disconnect the load, or restart the UPS.

Remove the plastic cover of the Mini slot.
Insert and secure the card with the screws.

SAFETY INSTRUCTIONS

The relay contacts and the card inputs are galvanically isolated from the UPS. It is strictly forbidden to apply a voltage greater than 40 V AC or 50 V DC to the contacts. Disregard for this restriction may endanger human life, damage equipment and cancel the manufacturer warranty.

ELECTROMAGNETIC COMPATIBILITY

When correctly installed and used in accordance with manufacturer instructions, the card complies with the following standards:

ITE (Information Technology Equipment) safety: IEC/EN 60950-1 2005

WEEE

The crossed-out wheeled bin symbol indicates that waste electrical and electronic equipment should not be discarded together with unseparated household waste, but must be collected separately. The product should be handed in for recycling in accordance with the local environmental regulations for waste disposal. By separating waste electrical and electronic equip- ment, you will help reduce the volume of waste sent for incineration or land-fills and minimize any potential negative impact on human health and the environment.
