4-6 820XBA1097
4.2 Electrical installation
4.2.1 Important notes
-
Ensure appropriate activation when using current-operated
e.l.c.b.s.
-
For information on the installation according to EMC see
chapter 4.3
-
Prior to assembly and service operations, the personnel must
be free of electrostatic charge.
-
Unused control inputs and outputs should be covered with
plugs.
-
In case of condensation, connect the controller to the mains
voltage only after the visible humidity has evaporated.
-
Please observe the restricitons of each mains type!
Mains Operation of the controller Notes
With grounded neutral No restrictions Observe controller ratings
Operation of several 820X
controllers connected to a mains
3AC/N/PEandsymmetrical
distribution to the three outer
conductors excepted
-
Observe the load of the shared
N-conductor.
- r.m.s. current, see chapter 3.2
-
Possibly enlarge the cross-section
of the N-conductor.
With isolated neutral
(IT mains)
Operation with recommended
mainsfiltersisnotpossible
-
Mains filter will be destroyed if
”earth fault” occurs.
-
Contact Lenze.
With grounded phase Operation only possible with one
variant
