TRANSFER SWITCHES WITH INTEGRAL OVER CURRENT PROTECTION

For models of transfer switch with integral over current protection, the over current protection

must be set prior to operation. The equipment will be shipped from the factory with a long-

time current setting of 100% (of the equipment rating) and maximum short-

time/instantaneous current and time delay settings.

WARNING!

Do Not Energize this equipment until

device settings have been verified to

ensure proper system protection &

coordination. Failure to do so may

result in equipment failure.

Refer to Section 5.2.2 of this manual for additional information on operation of the Transfer

switch following an over current trip condition.

Refer to information supplied with the transfer switch documentation package for adjustment

procedures on the power switching units over current protection trip unit. Contact the factory

if any additional information is required.

3.3.

TRANSFER SWITCHES WITH MULTI-TAP VOLTAGE CAPABILITY

If the transfer switch has programmable multi-tap voltage capability (i.e. ATS Model Code

with Voltage Code “Y”), confirm the transfer switch has been configured for the correct

system voltage prior to installation.

WARNING!

Failure to confirm and match transfer

switch voltage with the system voltage

could cause serious equipment damage.

The voltage selections and connections are shown on the engineered drawings attached to

each transfer switch. The factory default settings will be indicated on the calibration label

attached on the inside of the enclosure door (supplied loose on open style models). A blank

label is included to record the applicable settings if the configuration is changed from the

factory default settings.
