Section 2:
Installing a GRAFIK Eye
This section explains how to install a GRAFIK Eye control unit and make sure it is properly operating all connected
loads.
Step 1: Turn the Power OFF
CAUTION! Before continuing with the installation, make sure the power is turned OFF at the panel supplying
power to the control unit. Do not perform any wiring with the power ON.

Control Link Specifications
Total length of control link may be no more than 2000 feet (610
m). This distance is based on proper shielding on the twisted
shielded pair, and on #12 AWG (2.5 mm
terminal 1 and terminal 2 of the control link. If unapproved cable
or smaller wire is used, this limit is affected:

Total number of control unit addresses = 8 maximum
Note: G RX-4116/4516 has 2 addresses
GRX-4124/4524 has 3 addresses
Total number of wallstation or control interface addresses = 16 maximum
Total number of shade controller addresses = 8 maximum
Notes:
• Make wire connections inside the wallbox and panel or in a junction box (by others) within 8 ft. (2.4 m) of the
terminal.
• All control wiring is PELV (Class 2: USA). Do not place any of these wires in with line voltage (mains voltage) wiring.
• The order of controls within the control wiring is not important.
PELV (Class 2: USA) Notice
Wallstation circuits are classified as Class 2 circuits (U.S.A.) and PELV circuits (IEC). Unless otherwise specified,
the voltages do not exceed 24 V
Electrical Code (NEC
®
410, BS7671:1992 and other equivalent standards. When installing and wiring to these wallstations, follow all
applicable national and/or local wiring regulations. External circuits connected to input, output, RS232, DMX512,
and other communication terminals of wallstations, must be supplied from a listed Class 2 source or comply with
the requirements for PELV circuits, as applicable in your country.
