Dimensions: [mm] H63 x W38.5 x D48
Mounting: Snap-on rail mounting (35mm snap-on DIN rail / TS35)
Commissioning information:
The connection kit is delivered as individual parts and must be
correctly mounted on a snap-on DIN rail on site. The following
mounting sequence (starting on the left) must be observed:
1. 2 x through terminal (WK4/U/VO)
2. 4 x fuse terminal (WK 4TKG/U/VO),
3. 1 x Cover plate (AP 4 TK/VO).
The 4 x enclosed diode plugs must be mounted on the insulated
base terminals (snap-on). The enclosed labelling strips must
also be attached.
The connection between the frequency inverter and the
connection kit should be as short as possible. The use of a shielded connection cable is recommended. The shield must be
well earthed at both ends. The shield of the encoder cable must also be connected to PE.
