3. Installation instructions
Connections between the control panel and the luminaire modules is consisted of a 2 core twisted pair
cable.
The figure below shows the interior of the panel and the keyboard.
Please install the panel in a clean and dry environment with an ambient temperature of between 5°C
and 35°C. The panel uses for backup power a lead acid battery.
3.1. Choosing the correct cable
The cable between the panel and the GR-6057 modules must have the following specifications:
1. 2-core twisted pair cable. Normally the cables are unshielded but if the cable passes near
noisy/industrial environment the cables must be shielded.
2. The cable must have only 2 cores and the shield, no other cables.
3. The cable must have low resistance, below 25 Ohm/km. The total impedance of the cable of each
core from start to finish must not be more than 20 Ohm.
4. The capacitance of the cable must be low (below 200pF/m). The total capacitance of the whole
installation must not exceed 800nF.
