How to set formIt language?

Question

MODX

Hello, there is a site with several contexts and languages, respectively (ru, en, de...), and formIt is also used, with the following form template:

<form action="/" method="post" name="video" class="ajax_form white-popup-block">
  <input type="text" name="name" id="name" value="" />
  <span class="error error_name"></span>
  <input type="text" name="email" id="email" value="" />
  <span class="error error_email"></span>
  <input type="submit" value="form.send" class="f-bu f-bu-default" name="video-yes" id="yes_btn" /></form>

How can I make the language of the form be English in all contexts except 'ru'? Thank you.
