2.1 Installation
1. Connect with the controller
See the corresponding controller user manual for controller installation details.
2. Connect Surge Protection Device
The Automatic transfer switch is connected to an electronic circuit with a power supply, that is vulnerable to
overvoltage damage, therefore, it is recommended that users install Class C Surge Protection Devices when using
automatic transfer switches, and the right wiring methods. See Appendix 1 (Surge Protection Device) for additional
details and recommended wiring methods.
3. Isolation function
The C2ADTL transfer switch is not suitable for isolation, and a switch-disconnector must be installed when
isolation function is needed.
2.1.1 Installation of Transfer Switch
Install the transfer switch to the cabinet according to the mounting dimensions shown in Figure 2-1.

1. Make sure to install the bridging busbar in such a way that its long center plate must make solid contact with the arc chamber
surface.
2. The bridging busbar can only be used for the LOAD SIDE of the switch.
3. Recommended torque to be used for the bridging busbar connecting screws: M8: 11 N·m.
2. Pole Partition
The pole partition is used to isolate and insulate the poles and ensure electric safety.
The installation procedures are as follows:
1) The pole partition as shown in Figure 2-3.

1. The gap in the pole partition is used to make room for the label covers and the base of the switch. If the gap is inserted in the
wrong direction, the label cover will not be able to be snapped back into position correctly.
2. Make sure that the correct label (LINE versus LOAD) is showing on the correct side AND make sure that the corresponding
phase labels on the cover (A/B/C/N) are in their correct positions as well with A Phase being closest to the main gear driver box
area.

2. When mounting an additional auxiliary contact on top of another contact, remove the sticker located in the center of
the contact that is being mounted, then like before, with the screw holes facing outward, snap the 4 claws into the
corresponding 4 holes on the previously installed auxiliary contact and then force it into position, as shown in Figure
2-8. If installing an additional auxiliary contact on top of another, need to remove sticker on the base auxiliary contact,
otherwise do not remove sticker to protect auxiliary contact from dust debris.

No Sticker Sticker
Figure 2-8 Auxiliary Contact Installation on Top of Another Contact
NOTICE
1. The center sticker on the auxiliary contact that is in direct contact with the side plate must be removed before installation of the
additional auxilary contact on top of it.
2. Keep the center sticker on the outer most auxiliary contact in place to avoid any debris or dust from getting inside.
3. The maximum auxiliary contacts that can be used on the side plate are 8 contact s, or 2 contacts per slot location. There are 4
slot locations.
3. Next, punch out the small holes on the side plate in order to insert the cable clamps into the small round holes on
the transfer switch side plate. See figure 2-9. There should be 2 clamps packaged together with each optional
auxiliary contact.
Figure 2-9 Cable Clamp
4. After wiring the auxiliary contacts, affix the corresponding cable with the closest cable clamp using a cable tie to
facilitate and optimize the wiring layout as shown in Figure 2-10.

2.2 Operation
2.2.1 Manual Operation
The procedures are as follows:
1. Move the auto/manual toggle switch from ‘AUTO’ (automatic) to ‘MANUAL’ position, as shown in Figure 2-11.
Figure 2-11 Switching the toggle Switch from AUTO to MANUAL
CAUTION
！
Make sure toggle switch lines up with the correct indication position mark
2. Insert the operating handle into the handle hole, and rotate the handle according to the position and direction
shown in the position indicator widow.
1) When the window initially displays ‘OFF’(Center-off Position), do the following operations as needed:
If you need to switch to Position I (Normal Source), rotate the handle 90 degrees counter-clockwise. After
hearing a ‘click', and the window displays ‘I’, it indicates that the position has been successfully switched to
Position I.
If you need to switch to Position II (Emergency Source), rotate the handle 90 degrees clockwise. After hearing a
‘click', and the window displays ‘II’, it indicates that the position has successfully switched to Position II.
2) When the window initially displays ‘I’(Normal Source), do the following operations as needed:
If you need to switch it to the Position OFF (Center-Off Position), rotate the handle 90 degrees clockwise. After
hearing a 'click', and the window displays ‘OFF’, it indicates that the position has successfully switched to
Position OFF.
If you need to switch it to Position II (Emergency Source), rotate the handle 180 degrees clockwise.After
hearing a 'click’, and the window displays ‘II’, it indicates that the position has successfully switched to Position
II.
3) When the window initially displays ‘II’(Emergency Source), do the following operations as needed:
If you need to switch it to the OFF Position (Center-off Position), rotate the handle 90 degrees counter-clockwise.
After hearing a 'click', and the window displays ‘OFF’, it indicates that the position has successfully switched to
the Position OFF.
If you need to switch it to Position I (Normal Source), rotate the handle 180 degrees counter-clockwise. After
hearing a 'click', and the window displays ‘I’, it indicates that the position has successfully switched to Position I.
The detailed handle rotation positions are shown in Figure 2-12.

CAUTION
！
1. If the toggle switch is not in the right position (MANUAL), the handle cannot be inserted.
2. The manual handle operation torque should greater than 8 N·m.
3. Due to high torque of the handle during operation, the operator should be careful to avoid from getting injured from touching the
toggle switch and padlock pull tab objects portruding from the surface.
2.2.2 Auto Operation
1. Remove the operating handle from the handle hole.
2. Move the auto/manual toggle switch from ‘MANUAL’ to ‘AUTO’ Position, as shown in Figure 2-13.
Figure 2-13 Switching Toggle from MANUAL to AUTO
CAUTION
！
Make sure toggle switch lines up with the correct indication position mark
3. Once auto/manual toggle switch is in the 'AUTO' Position, the switch will automatically transfer to the position that
is currently set in the controller. (For a description of how to set the positions in the controller, refer to the Series 230
C1000 Controller User Manual or Series 230 C2000 Controller User Manual).
WARNING
！
1.If the handle has not been removed, the auto/manual toggle switch cannot be switched to the 'AUTO' Position.
2.After the manual operation, the operator must ensure that the auto/manual toggle switch moves back to the 'AUTO' Position,
and the auto/manual toggle switch lines up with the 'AUTO' Position indicator mark. Otherwise, the transfer switch will not work
in Automatic Mode.
2.2.3 Padlock
In order for the Padlock Pull Tab to function properly, one must ensure that the switch is in Manual Mode AND the
handle is in the Position Off. To do this, do the following in this order:
1. Ensure that the auto/manual toggle switch is in ‘MANUAL’ position.
CAUTION
！
If the auto/manual toggle switch is not in MANUAL position, the padlock pull-tab cannot be pulled up.
Indication Position Mark

16 Chapter 2 Installation And Operation
ASCO Series 230 C2ADTL Transfer Switch User Manual
2. Ensure that ‘OFF’ is displayed in the position indicator window. If not, use the manual operating handle to switch
the transfer switch to Position OFF according to the directions shown in the position indicator window.
CAUTION
！
When the switch is not in OFF Position, the padlock pull-tab cannot be pulled in place.
3. Finally, pull the padlock pull-tab out and lift up to expose the lock hole. Then insert the proper padlock into the hole
to lock it.
CAUTION
！
The specified diameter of the C2ADTL transfer switch padlock must be φ5mm to φ6mm.
