Motor Terminals; Wiring - Velux KFX 210 Instructions Manual

Motor terminals

Each terminal is intended for 24 V DC and max 10 A.
Control unit KFC 210 (10 A)
In this example, only motor terminal 1 is active.
Max 4 smoke ventilation windows
GGL/GGU -K-- ----40
or
1 smoke ventilation window CSP can be con-
nected to the control unit.
Control unit KFC 220 (2 x 10 A)
In this example, both motor terminals 1 and 2 are
active.
Max 8 smoke ventilation windows
GGL/GGU -K-- ----40 (max 4 windows per motor
terminal)
or
2 smoke ventilation windows CSP can be con-
nected to the control unit.
Terminal module
To ensure cable monitoring, the terminal module
in the control unit must be moved to the last con-
nection between smoke ventilation windows
GGL/GGU -K-- ----40 or CSP and the cables from
the control unit.
NB: In case motors operate in the wrong direc-
tion, transpose the two motor cables in the
terminal.

Wiring

Electrical cables should be drawn according to regulations by qualified per-
sonnel. The control system and its cables should be installed in compliance
with current national legislation and the requirements of local authorities.
Maximum cable length/prescribed cross-sectional size of
cables
The maximum allowed cable lengths between control unit and motor and the
prescribed cross sectional sizes of the cables are given in the table below. The
cable must be protected according to National/European Standards.
Calculation of max. cable length: 56 x A/l
A is cable cross-section and I is max motor current in total.
Allowed maximum voltage drop in the cable: 2 V
Operation current: The total of all motor currents.
