RECTIFIER INSTALLATION - Mains Supply Balancing Effect

The Flatpack PRSB system may be expanded to a maximum of 6 Flatpack 1500 rectifiers. In order to load the AC supply net evenly similar current load from the 3 phases of the mains supply it is advisable to mount the required number of rectifiers in the following order:

Figure 4: Rectifier mounting order to load the mains supply evenly

When possible, mount an equal number of rectifiers on each phase, L1, L2 and L3.

RECTIFIER INSTALLATION - Handles and Locking Mechanism The Flatpack 1500 rectifier module is equipped with handles that serve two purposes:

Locking the module into position

Open both handles, insert and plug the module into power shelf. Then lock it into position by rotating the handles upwards and pushing them firmly home. Failure to do so will prevent the module from making proper contact.

Figure 5: Module with released handles

Pulling the module out Unlock and release the handles by inserting a small flat screwdriver into the upper holes. Do not use excessive force. The handles will release and pop out. When both handles are released, use them to pull out the module.

Do not hold or carry the rectifier by its handles.

FAN & HEATER OPERATION

The fan runs as soon as the temperature in the cabinet passes 25oC (77F). Hysteresis is 1C (1.8F).

The heater is controlled through a thermostat and the heater starts up at 5C (41F).

ALARM RELAY OUTPUTS AND SIGNAL CONNECTIONS

The digital inputs are configured as fail-safe, i.e. if the input is enabled, it will trigger an alarm when the input is open. If several external devices are to be connected to the same digital input, they must be connected in series.

The alarm relays are also operated in fail-safe, i.e. the relays are energized when there is no alarm. The description below describes the pin out in normal state, i.e. the REL output is closed to COM in normal operation and the REL output is open to COM in an alarm-state.

Alarm relay specifications:

Nominal switching capacity 2A/30VDC

Maximum switching power 60W (resistive load)

Maximum switching voltage 220VDC
