terminals, the links arranged as shown in Fig. 4. The winding will not be capable of re-connection
for any other voltage.
7.5: Explosion Proof actuators are only arranged for the terminal voltage shown on the nameplate.
Three terminal posts will be visible when the cover plate is removed under the required
