Page 2: Regulatory Information
Redundancy The Helix line of power supplies adds a layer of redundancy over the typical FPO power supply. Only the FPO power supply is redundant - any distribution in the system is not redundant. Also, the Helix cannot overcome any problems in the field wiring or load devices - if a short circuit shuts down the main supply, the backup supply will also be shut down by this short circuit. -
Page 3: Installation
120/230VAC input jumpers to be configured by the installer. Both FPO power supplies must be set to the same output voltage for proper operation. Do not rewire or reconfigure any other portion of the Helix power supply. - Page 4 Do not connect any load directly to either FPO power supply in the Helix system - all load connections should be made at or after...
- Page 5 The illustration in this section depicts a Helix system using two FPO75 power supplies. Connections and configuration are the same for Helix systems using different FPO models - consult the FPO power supply manual for locations of the noted items.
- Page 6 FPO1 Battery Connection - Do not connect a back- in the Helix system. These are a redundant equivalent of the up battery to FPO1. The backup battery set should be DC1 quick disconnect terminals on a typical FPO power connected to FPO2.
- Page 7 Rack Mount Field Wiring Connections Rack Mount Helix models are pre-configured for AC Input and DC Output voltage. All models are single voltage and, although FAI Inputs are present, FAI control is not available. ...

- Page 9 Fault Output Connections In order to monitor both FPO power supplies for problems, it is imperative that AC and System Fault contacts on both FPO power supplies be monitored. They may either be monitored separately or commoned into one or two outputs. Seperate Outputs FPO1 FPO1...
- Page 10 Veryfing System Operation To verify system operation, power the system and connect the battery to FPO2. Measure the Helix voltage at the DC+/- terminals. Remove the AC connector from FPO1 while continuing to monitor the Helix voltage. Verify that the voltage remains the same...
- Page 11 Helix Audible Alarms The Helix board has an audible alarm that will sound on various fault conditions that require immediate attention to maintain redundancy. The fault conditions include: • The two FPO boards connected are not set to the same output voltage (i.e. one supply set for a 12V Output and the other set for 24V) •...
