run length, number of devices on the Modbus run, type of interconnection cable, and baud rate
selected.
A maximum of one terminating resistor should be used when the Modbus interface of multiple
units are daisy chained together and connected to one master Modbus device. The optional
120 ohm Modbus terminating resistor is frequently not necessary, and may in fact interfere with
proper communications operation under some circumstances. Shorter connections typically
perform quite well without a termination resistor.
#4 - Sync/CAN
8-Pin Phoenix-style connector
 Pin 1 is CAN_L
 Pin 2 is CAN_H
 Pin 3 is CAN isolated ground
 Pin 4 is Sync RX_N
 Pin 5 is Sync RX_P
 Pin 6 is Sync TX_N
 Pin 7 is Sync TX_P
 Pin 8 is Sync isolated ground
NOTE: The CAN interface is reserved for future use.
#5 - Transfer Switch
8-Pin Phoenix-style connector
 J16 pin 1 Island (24 Vdc)
 J16 pin 2 Island Return (24 Vdc Return)
 J16 pin 3 Island Acknowledge Return (24 Vdc Return)
 J16 pin 4 Island Acknowledge (24 Vdc)
To enable voltage-forming (islanded operation), both pin 2 and pin 3 on J16 must be connected
ground, or left open. Connect to 24 Vdc to ensure the system never attemps to island while the
Facility Power Control Method is enabled.
These inputs are designed to interface with external third-party Islanding Switchgear
which allows the PCS to move between grid-following and grid-forming modes in a
seamless, blinkfree fashion to support critical loads. Detailing the Islanding Switchgear
application is beyond the scope of this initial Quick Start Guide. If not using third-party
Islanding Switchgear, leave J16 pins open.
