Module Replacement

This section contains instructions for replacing all TeSys™ island modules except the bus coupler:

NOTE: The original device and the replacement device must have the same commercial reference number.

DANGER
Hazard of Electric Shock, Explosion, or Arc Flash Turn off all power before working on or inside the equipment. Failure to follow these instructions will result in death or serious injury.

Disconnect all power from the island.
Remove the existing module from the DIN rail.

NOTE: When replacing two speed, two direction, or Y/D starters, also remove the adjacent starter. Then remove any accessories used to connect the starters, so the accessories can be reused to install the replacement module.
Install the replacement module according to the instructions in the TeSys island Installation Guide:
- Installing Standard Starters and SIL Starters
- Mounting Power Interface Modules on DIN Rail
- Mounting the I/O and Interface Modules on DIN Rail
NOTE: When replacing two speed, two direction, or Y/D starters, install any accessories to connect the replacement starter to the adjacent starter, before installing the modules on the DIN rail.
Apply 24 Vdc power to the island.

NOTE: Do not apply the mains power at this time.
Use Test mode to verify that the device is operating correctly.
Apply the mains power to the island, initiating the boot process. Observe the LEDs until they turn green, indicating that the island has entered the operating state. The boot process takes about two minutes.
