Assembly
1. Mount the current transformer on the primary conductor by
directing the primary conductor (copper bus bar respectively
round conductor) through the window opening of the current
transformer housing.
2. The device can be fixed either directly on the primary conductor
or on a ground plate. A mounting kit is part of the delivery. It
contains plastite-screws, red isolation covers and foot angles.
3. On each side of the housing are swells with threaded holes. The
device can be fixed directly on the bus bars by usage of the
plastite-screws (see photo on the left). If the device is to be
mounted on a ground plate, the foot angles are to be used.
4. Current transformer types CTB31.35 and CTB 41.35 can also be
mounted on a 35mm-DIN-hat rail by using a snap-on mounting
(accessory, article-no.: 50.2.8095).
5. Connect the conductors according to the drawings .
6. Please see the pictograph on the bottom of the next page (Cage-
Clamp) for the correct mounting of the secondary terminal
clamps.
