Electrical Connection (Europe-Version Only) - CompAir L15 Operating And Service Manual

6. Preparations for commissioning
6.4 Electrical connection (EUROPE-
Version only)
Compressor units are finished in the factory according
to standard EN60204 (industrial machinery). Please
observe the following important notes:
Warning
The power supply to the compressor side
has to be fitted for industrial equipment and
fulfilling the requirements of EN60204-
1/IEC60204-1. To avoid strong damages and
fire on the power electric components, any
kind of operation outside of the stated limits
of EN60204-1/IEC60204-1 is inadmissible.
Important
The customer has to connect a main switch in the
incoming line of the compressor unit (unless
factory-mounted as special accessories)
(DIN EN 1012 - 1).
If this switch does not provide short-circuit and
overload protection for the system, suitable back-
up fuses have to be installed according to
EN 60269-1 (low voltage directive ) (see table).
The main switch must meet the requirements of the
safety standard EN 60 204-1 (electrical equipment
of machinery) as well as of EN 60947-2 (low-
voltage switchgear and control gear (circuit-
breakers)).
The electrical connection and protective measures
have to be installed in accordance with VDE, BS or
local regulations. As a rule, additional instructions
of the relevant power supplier have also to be
adhered to.
The electrical connections must be made by an
authorized specialist.
Attention: Interference voltage!
If external electric circuits, which cannot be cut out
via the main switch, are connected to the control,
these have to be identified according to EN60204.
Warning signs have to be fixed near the main
switch and near these electric circuits. In addition,
these conductors have to be laid separately and/or
identified by colors. Work on control cabinets may
only be carried out by electrotechnical specialists.
If the installation conditions of the system differ
from the conditions described in EN60204, please
contact your technical adviser.

To establish an electrical connection, proceed as
follows:
Route the supply cable through the cable gland
(-1 - Fig. 12) on the control cabinet and tighten screws.
Connect the supply line to the connecting terminals as
shown in the circuit diagram.
