Wiring Interconnections

All wiring must be the proper size, properly supported and

protected by conduit.

Complete the following connections between the transfer

switch, main distribution panel, utility power and generator,

as shown on the next page.

WARNING

Low voltage wire cannot be installed in same

conduit as power voltage wiring.

Failure to follow above warning could cause personal

injury, damage and/or malfunction of equipment.

High Voltage Wiring

1. Ensure utility power is turned OFF. Connect utility

feeder conductors to transfer switch terminals marked

“UTILITY CONNECTION”. Connect utility live to “N1”

and utility neutral to “N2”.

2. Connect distribution panel feeder conductors to transfer

switch terminals marked “LOAD CONNECTION”.

Connect live to “T1” and neutral to “T2”.

3. Connect distribution panel Ground conductor to the

transfer switch “GND” terminal.

NOTE: Assure grounding electrode conductor is connected

and bonded per applicable federal, state and local codes,

standards and regulations.

Generator feeder conductors are shown below:

4. Connect generator feeder conductor from the generator

circuit breaker terminal “E1” to transfer switch terminal

marked “GENERATOR CONNECTION” terminal “E1”

(see diagram at top of next column). This conductor

should pass through hole of current transformer before

making the connection.

5. Connect other generator feeder conductor from the

generator circuit breaker terminal “E2” to transfer

switch terminal marked “NEUTRAL”. This conductor

should pass through hole of current transformer before

making the connection.

6. Connect a cable from transfer switch terminal

marked “Neutral” to transfer switch terminal marked

“GENERATOR CONNECTION” terminal “E2”.

7. Connect a cable from transfer switch terminal marked

“Neutral” to transfer switch terminal marked “Ground”.

NOTE: This connection grounds the neutral side of the

generator output, and is required for correct operation of

protection devices in the installation.

8. Plug in current transformer leads into “CT1” and “CT2”

on control module.

9. Connect generator Ground conductor from the control

panel to the transfer switch “GND” terminal.

NOTE: Assure generator equipment grounding conductor

is connected per applicable federal, state and local codes,

standards and regulations.

10. Connect generator “UTILITY 230 VAC” terminals to

transfer switch “UTILITY 230 VAC” terminals (F1, F2).

Use minimum 2.5mm

conductors.

NOTE: Replace with fuse of same type and rating, 600 volt,

2 amp.

11. Tighten all wire connections/fasteners to proper torque

as shown below.

Low Voltage Wiring

1. Using 1.0mm

twisted pair conductors, no greater than

60 m in length, connect Tx Rx and Tx Rx Ground from

the generator control panel to the GND and T/R on the

transfer switch control board.

2. Tighten all wire connections/fasteners to proper torque

as shown on next page.
