Installation - Electrical
• However, for any intervention in the AFD, the indicated
time on the label of the AFD must be respected.
Before installing the chiller with AFD, the user must
evaluate the potential electromagnetic problems in the
surrounding area. The following should be considered:
a) the presence above , below and adjacent to the unit of
for example: welding equipment or other power cables,
control cables or signaling and telephone cables;
b) receivers and transmitters, radio and television;
c) computer and other control equipment ;
d) the critical safety equipment, eg protection of
industrial equipment ;

f) the immunity of other equipment in the environment.

The user must ensure that the other materials used
45

in the environment are compatible. This may require
48

Minimum circuit ampacities and other unit electrical
data is on the unit nameplate. See the unit order

schematics and connection diagrams are shipped with
the unit.
