System Communications and Capacities

PELV (Class 2: USA) cable can be used to connect GRAFIK Eye 4000 control units, wallstations, and other
accessories. You can link up to 8 control units to control up to 64 zones, and add up to 16 wallstations and 8
shade controllers (SG-SVC) for a total of 32 control points. 16-zone control units count as 2 addresses and 2
control units, and 24-zone control units count as 3 addresses and 3 control units. Note that wallstations control
scenes (which can include light and shade settings); shade controllers control only shades. 16- and 24-zone
control units and slider models do not have shade zones.
PELV (Class 2: USA) Cables
If your lighting system uses wallstations and/or multiple control units, PELV (Class 2: USA) wiring is needed to
supply power and carry communications between the control units and the wallstations. PELV (Class 2: USA) wiring
is also needed to connect other accessories.
Use properly certified PELV (Class 2: USA) cable. Each twisted pair in the PELV (Class 2: USA) wiring link should
consist of two stranded conductors and a drain/shield wire.
• The pair of #12 AWG (2.5 mm
• The pair of #22 AWG (1.0 mm
Note: L utron offers a one-cable, low-voltage solution: P/N GRX-CBL-46L (non-plenum) or GRX-PCBL-46L (plenum).
Check availability and applicable electrical codes in your area.
In countries that abide by the IEC regulations, PELV is commonly referred to as Protective Extra-Low Voltage.
A PELV circuit is a grounded circuit in which the voltage cannot exceed 50 V or 120 V
source must be supplied by a safety isolating transformer or equivalent.
In Europe, acceptable types of cable include HAR certified cable with insulated cores enclosed in a sheath. This
cable must bear the appropriate certification mark pertaining to national wiring rules for fixed installations. If
certified cable with insulated cores enclosed in a sheath is used for the power cables, the PELV wiring can be any
of the cables listed above.
