DANGER

!

The TR1 Series VFD contains dangerous
voltages when connected to line voltage.
After disconnecting from the line, wait at
least 15 minutes, 30 minutes for 550-600V
units, before touching any electrical compo­nents. Only a competent electrician should
carry out the electrical installation. Improper
installation of the motor or the TR1 may
cause equipment failure, serious injury or
death. Follow this manual, National Electri­cal Codes and local safety codes.

WARNING

!

Many electronic components of the TR1
Series VFD are sensitive to Electrostatic
Discharge (ESD). Voltages so low that they
cannot be felt, seen or heard, can reduce the
life, affect performance, or completely
destroy sensitive electronic components.

When performing service, proper ESD
equipment should be used to prevent pos­sible damage from occurring.

CAUTION

!

It is the responsibility of the user or the
person installing the TR1 Series VFD to
provide proper grounding, as well as motor
overload and branch circuit protection
according to the National Electrical Code
and local codes.

Single Relay Option Card

The ratings of the relay contacts are the same as the standard Form C relay.
Output terminals are located on the single relay option card. The terminals
are 110, 111, and 112. Input to the relay is through terminals 113 and 114,
also located on the option card. Input to the coil in the relay is 24 VDC, 10
mA nominal. The input to the relay is polarity sensitive. The Form C relay on
the option card may be driven by either the standard Form A relay or one of
the transistorized outputs.
