Installation

Connecting the battery / UPS
● 2 D-Sub connectors + battery 3.6 Ah ⇒
No additional base load resistance required
● 5 D-Sub connectors + battery 36 Ah ⇒
Additional base load resistance of 34 kΩ required
Calculation
– I = [36 Ah / 1.8 Ah] × 7 μA - (7 μA × 5) = 105 μA
ext
– R = 3.6 V / 105 μA = 3.6 V / 0.000105 A = 34 kΩ
ext
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.
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)
A Shielded lines, e.g. (2x0,5)C; connect cable shield to
connection
R External resistor: If you use a bigger battery (> 1.8 Ah) at one

RGS0001/K01 D-Sub connector only, connect an additional ex‐
ternal resistor (value of R
capacity").
