2 Overview

2.1 Introduction

The RMS-RELAY01A card is installed in an optional card slot on the UPS and supports hot

swap. The dry contact card provides six alarm dry contact outputs (normal mode, battery

mode, bypass mode, battery undervoltage, bypass backfeed, and UPS faults) and two dry

contract control inputs (one is for shutdown signals, and the other is reserved).

For UPS5000-A-(30 kVA–120 kVA), the output dry contacts are available, and input dry contacts are

unavailable.

Table 2-1 lists basic specifications of the RMS-RELAY01A card.

3.2 DB25 Cable

Figure 3-2 DB25 cable

The DB25 cable, which is delivered along with the RMS-RELAY01A card, is 1.5 meters long.

To increase the length, add a magnetic ring to the connector of the DB25 cable. Table 3-2 lists

the specifications of magnetic rings from three vendors.

4.3 Installation Procedure

The methods for installing RMS-RELAY01A cards are the same on different UPSs. The

RMS-RELAY01A card is installed in the optional card slot INTELLISLOT at the rear panel

of the UPS2000 and installed in the slot for dry contact card at the rear panel of the

UPS5000-A. The installation position of RMS-RELAY01A cards based on actual conditions.

Procedure

Step 1 Check that the following items are available. One RMS-RELAY01A card, one DB25 cable,

and one RMS-RELAY01A User Manual.

Step 2 Remove the optional card slot cover from the UPS, as shown in Figure 4-1. Keep the screws

for use in Step 3, and the cover for future use.

Figure 4-1 Removing the optional card slot cover

Step 3 Insert the RMS-RELAY01A into the optional card slot along the guide rails, as shown in

Figure 4-2, and then tighten the screws.

The card uses M3 screws. The recommended torque is 0.5 N·m.

ECO mode, this dry contact is enabled. The value ranges from Dry contact1 to Dry

contact6. The default value is Dry contact1.

Battery mode parameter

RMS-RELAY01A




13

Set the output dry contact associated with battery mode. When the UPS is in battery or

battery ECO mode, this dry contact is enabled. The value ranges from Dry contact1 to

Dry contact6. The default value is Dry contact2.

Bypass mode parameter

Set the output dry contact associated with bypass mode. When the UPS is in bypass or

ECO mode, this dry contact is enabled. The value ranges from Dry contact1 to Dry


Batt. undervolt parameter

Set the output dry contact associated with low battery voltage. When the system battery

voltage is low, this dry contact is enabled. The value ranges from Dry contact1 to Dry


BPS backfeed parameter

Set the output dry contact associated with bypass backfeed. When a bypass backfeed

alarm is generated, this dry contact is enabled. The value ranges from Dry contact1 to

Dry contact6. The default value is Dry contact5.

Faulty UPS parameter

Set the output dry contact associated with UPS faults. When a critical alarm is generated,

this dry contact is enabled. The value ranges from Dry contact1 to Dry contact6. The
