Installation and Connection
Selection of the supply voltage
15 V
24 V or external
supply via the control
control card
The maximum load capacity is dependant on the selected voltage
supply.
Max. load capacity with 15V internal supply:300 mA
Max. load capacity with 24 V internal supply:170 mA
Max. load capacity with an external 24V supply 1 A (dependent on the
external voltage source)
The specified currents are reduced by any current drawn on the second
interface X3B.
Note: For 5V TTL encoders, a 5V supply is available on second interface,
X3B terminal 7.
If the encoder has no zero channel, connect N+ to 5V and N- to com.
For maximum noise immunity, the encoder cable shall consist of individu-
ally shielded twisted pairs with one overall shield. The individual shields
should be connected to 0V (com) pin 8 on the X3A terminal strip and be
kept electrically isolated from the outer shield. The outer shield should
be connected to earth ground on the elevator drive.

The cable shall be kept a minimum of 8 inches (20 cm) away from
all wires having greater than 24VDC on them. For best results run
the encoder cable in a separate conduit from the controller to the
motor.
