Frequency converter FKO - Brinkmann Pumps

Important information
1.4.3 Commissioning
WARNING
Danger of injury through electric shock.
Non-observance of warnings can result in serious injury or damage.
� Only hard-wired network connections are permitted. The device must be
grounded (DIN EN 61140; VDE 0140-1).
� Frequency converters of the FKO series can contain contact currents
(leakage currents) > 3.5 mA. According to chapter 4.3.5.5.2 of DIN EN
61800-5-1, a reinforced protective ground wire (at least 10 mm 2 Cu or
16 mm 2 Al) must be used.
� If three-phase frequency converters are in use, it is not permitted to use
standard type A FI protection switches, or RCDs (residual currentoperated
protective devices) to protect from direct or indirect contact.
According to DIN VDE 0160, section 5.5.2 and EN 50178, section
5.2.11.1, the FI protection switch must be universal current sensitive
(RCD type B).
� The following terminals can lead to dangerous currents even when the
motor is not running:
– Supply terminals X1: L1, L2, L3
– Motor connection terminals X2: U, V, W
– Connecting terminals X6, X7: Relay contacts for relays 1 and 2
� If different voltages are in use (e.g. +24 V/230 V), crossing cable runs
are never permitted. The operator must also ensure compliance with the
applicable regulations (e.g. double or strengthened insulation acc. to DIN
EN 61800-5-1).
� The drive control contains components susceptible to electrical
discharge. These components can be destroyed through improper
handling; therefore, precautionary measures against electrostatic
charges must be taken when work is performed on these components.
