6. Commissioning
6.1. Check and ensure the following before performing commis-
sioning:
• All mechanical and electrical protective devices must be attached
640
13-07-22
COPRA 4.5 kW / 8 kW
and connected.
• Secure touch protection as per DIN EN ISO 13857 based on the
COPRA 1.3 kW
installation conditions.
• Design guards in such a way that no falling objects are drawn in by
9 mm
L1
L2 L3
PE
the fan (DIN EN 60529).

• Check the duct system and fan for foreign objects (tools, small
parts, construction waste, etc.and remove where appropriate.
• Check that impeller is free by turning it manually.
• Check the current type, voltage and frequency of the mains
connection to ensure that it matches the type plate of the fan or
motor.
641
• Check that connected elements are working properly.

up. The suitability of the protective devices and their fixtures to
the fan must be assessed within the overall safety concept of the
installation.
NOTE
641

The entire system must be assessed in the concrete application to
640
ensure compliance with applicable standards and directives with

the impeller by comparing the rotary direction arrow on the fan..
CAUTION
Risk of injury from rotating impeller. Wait for the impeller to come

Once the operating speed of the fan has been reached, immediately
measure the current consumption and compare it with the nominal
current stated on the motor or fan type plate. If overcurrent
persists, shut down the device immediately.

NOTICE
Check that fan runs smoothly. If unusual oscillations, vibrations,
9 mm
temperatures and bearing noises are determined, the device must

L2 L3
PE
be shut down immediately. The impeller must not drag against the
inlet nozzle (audible test) under operating conditions. If it continues
to drag, shut down the fan immediately.
