Wallstation Installation
Wallstation Wiring: Panel with up to Ten Wallstation Controls
Each panel with a power supply can power up to ten Wallstation Controls. If you need to power more than ten
Wallstation Controls from one panel, install an external 24 V
Maximum of 300 m (1 000 ft) between the Control Unit and the second Wallstation. For longer distances, use
an external PELV rated 24 V
IMPORTANT WIRING NOTE:
Daisy-chain the terminal 1, terminal 2, terminal 3, and terminal 4 connections to the panel and
Wallstation Controls.
Note: Do not allow PELV wires to contact line/mains wires.
Control Station Device (CSD) Link Wiring
• Use low-voltage PELV wiring to connect Wallstations
to the panel link.
• Make connections inside the wallbox or in a switch/
junction box with a maximum wire length of 2,5 m
(8 ft) from the link to the Wallstation.
• Strip 9 mm (3/8 in) insulation from both twisted pairs
in the wallbox.
• Two 1,0 mm
(18 AWG) conductors for common
2
(terminal 1) and 24 V
in terminals. Connect as shown.
• One shielded, twisted pair 0,5 mm
data link (terminals 3 and 4).
• Connect Drain/Shield as shown. Do not connect
to Ground (Earth) or Wallstation. Connect the bare
drain wires and cut off the outside shield.
Note: Some Wallstations have a "D" terminal for
Drain. The Drain/Shield wire may be connected to
this terminal.
Contact Closure Input Wiring
• Use PELV/SELV wiring to connect the contact
closure inputs to the Wallstation.
• Inputs must be dry contact closure or ground
referenced solid-state outputs.
• Wallstation is miswire protected up to 36 V.
• Outputs must stay in the closed or open states for
at least 40 ms in order to be recognized by the
Wallstation.
