2 D-Sub conn battery 3.6 Ah ⇒
No additional base load resistance required

5 D-Sub conn battery 36 Ah ⇒
Additional base load resistance of 34 kΩ required

The examples contain guide values for the base load resistance.
The required base load resistance cannot be calculated by means
of the capacity for every lithium battery.
A lithium battery with a 5-fold higher capacity might possibly re‐
quire not more that a 3-fold higher base load current. If you use
other batteries than ER6C (1800 mAh), ask the battery manufac‐
turer for the required base load current.
Installation
Connecting the battery / UPS
Risk of injury by exploding batteries!
WARNING
Pay attention to
●
the correct polarity when connecting the battery
NOTICE! Incorrect polarity might damage the encoder system.
●
the correct dimensioning of the external resistor
●
the safety instructions of the battery manufacturer
3.6 V
Direct voltage source (battery or UPS)

External resistor: If you use a bigger battery (> 1.8 Ah) at one
/K01 D-Sub connector only, connect an additional ex‐
ternal resistor (value of R
