Safety clamp

To maintain the galvanic isolation (PELV) between the
control terminals and high-voltage terminals, the ac-
companying safety clamp must be attached to VLT
2803-2815, 200-240 V, and VLT 2805-2815, 380-480
V. Attach the safety clamp to the strain relief plate with
the two screws provided.

Prefuses

For all unit types, external prefuses must be fitted in
the line supply to the adjustable frequency drive. For
UL/cUL applications with a line voltage of 200-240
Volt, use prefuses type Bussmann KTN-R (200-240
Volt) or Ferraz Shawmut type ATMR (max. 30A). For
UL/cUL applications with a line voltage of 380-480
Volt, use prefuses type Bussmann KTS-R (380-480
Volt).

AC line connection

All drives that are equipped with an RFI
filter cannot be connected to a grounded
DELTA or IT mains/AC line system.

NOTE

Check that the AC voltage matches the
voltage rating of the drive. The drive rating
is on the drive nameplate. See

Technical

data

in this manual for correct dimension-

ing of cable cross-section.

For single phase 220-240 Volts input, attach the neu-

not be connected to AC line supplies in
which the voltage between phase and
ground is more than 300 Volts. Please
note that for the AC line for IT and the delta
ground the AC line voltage can exceed
300 Volts between phase and ground.
Units with type code R5 can be connected
