UPS Installation

Rescue Operation UPS Supply Requirements

The Elevator Core is designed to operate with a Single Phase 230V UPS supply with lower input voltage thresholds which are shown in the table below. The values below are only applicable while in Rescue Mode.

If the drive is not in Rescue Mode then the normal operating specifications must be used, these can be found in Turn On/Off Levels Specification.Turn On/Off Levels Specification

Current Requirements

UPS Power Supply

UPS must be connected to terminals L1 and L2

230VAC 1Ph

160VAC (226Vdc)

280VAC

Motor Rated current (P4-03) and considering overload, typically no greater than 200%

Note

The drive can also be operated from 2 phase 400V in case a phase is lost.

UPS Supply Connection Method

The connection method below details how the drive should be connected to a single phase UPS supply.

Required Contactor Sequencing

Example UPS Supply Connection

The image shows an example UPS power supply connection to the drive that provides a supply voltage during rescue operation.

  • The Rescue Supply Contactor must only be closed when the Main Contactor is open (Interlocking Mechanism)

  • A delay time of no less than 2 seconds must be included when changing over to/from UPS supply to/from mains supply mode.

  • The Main Supply Contactor and Rescue Supply Contactor must be interlocked so that both cannot be energised at the same time, failure to do so may result in damage to the UPS and/or contactor.

  • The drive will always wait until the next stop command (direction input removal) before rescue mode operation is activated and likewise when rescue mode is de-activated the drive will wait until the next stop command before changing back to normal mains supply operation.

Warning

Circuit protection must be provided.

Note

Any Digital Input can be used to activate rescue mode not just Digital Input 8 (DI8).

To change the Digital Input for Rescue Mode use P1-02 to select a different Macro or set P1-02 to 0 and create your own Macro using Group 12 to define the function of each Digital Input.
