Series 7400 Single Phase 1+N UPS

4.4Remote Alarm Monitor (RAM) for Single Module & “1 + 1” UPS System.

This will contain following items:

1.Remote Alarm Monitor for Single Module #270154000001.

2.Remote Alarm Monitor for 1+1 Module #270154000003.

This unit is always used in conjunction with Alarm interface PCB #100215120002, only. Remote Alarm Monitor enables the auxiliary alarm signals to be displayed at a remote station upto 200 meters from the main equipment.

The RAM is required to be mounted vertically. This is ideally suitable for wall mounting. However, this also can be mounted inside a panel. The cut out dimensions for the panel mounting, are as shown in the clamps provided for wall mounting are required to be removed. (Refer drawing).

There are total 9 alarms provided on the RAM. Each of the alarm initiates an audible alarm warning. This is, however, subject to a short time delay to prevent the warning being activated by transient conditions. Pressing the reset push button cancels the audible warning but the alarm indications remain until the condition is rectified. A test push button is also provided to ensure that all the LED’s are healthy.

Power Supply

The RAM contains a single-phase 230V a.c. mains driven power supply. Power is applied through a standard two-pin mains connector located at the backside of the RAM. This 2 pin male-

female type connector is marked as N L . The supply is rated to approximately 10 watts and hence can be tapped from any suitable source. This generates required DC power supply for functional requirement of the RAM. Once AC power is available to RAM, “POWER” indicating LED on RAM starts glowing. This indicates that RAM is ready for operation. This power supply is used to reproduce UPS mimic and display alarms.

Mimic and Alarm Connections

Refer figure 25 and 26.

For connection of RAM signals to interface PCB two different connectors are provided marked as RM-1 and RM-2. RM-1 is a six pin male-female connector and RM-2 is a 10 pin male-female connector. Both the connectors are with screwed terminals. The connection diagram of both the terminals with interface PCB is as shown in connection diagram. 24V d.c.supply is available on RM-3. This is required to be connected to M3: pin3 of Interface PCB. This 24 volts supply is required to be looped on interface PCB as shown with star marked connections. For connecting RAM and interface PCB’s, use multicore 1.5sq.mm. stranded conductor, flexible copper cable. RAM actually requires 16 such cores. However, it is advisable to provide spare cores and hence we recommend use of 24-core cable.

For connection diagram of 1+1 UPS system refer figure 27.
