Remarks regarding IP 20 enclosure
1. To connect ecosine evo line and load side terminals, the fingure guard has to be removed
as a first step, and be installed again when the line and load side terminals are
connected. The screw thread and torque value for all the frame sizes are:
|
Screw thread: M5
|
Screw torque value: 4Nm
2. The metal finger guard for frame sizes E, F and G are equipped
with grommets, whilst figner guard H is equipped with stepped
collars. Modify the stepped collars according to the cable
isolated diameter, 5-10mm margin is recommended to feed the
cable easier.
3. Note that if the cable lug is wider than the cross-section width/diameter of the finger guard
(see Table 20),do not add cable lugs before feeding all cables though the finger guard.
Crimp cable lug when the cables are fed through the finger guard.
4. Install shrinking tube for the uninsulated cable lug to fulfill the clearance and creepage
requirement.
Note:
In case the cables on the power terminals are installed without cable lug, it is
recommended to follow the maintenance manual closely. Maintenance manual is available on
your request per Schaffner contact.
