TVM Module
For 0-10 V, PWM, Tridonic
®
DSI, and DALI loads. Each TVM
controls two consecutive circuits of lighting and are the first
circuits in the panel. Maximum low-voltage ballast control
current: 50 mA per zone, 750 mA per panel. Dimming or
switching module is used to switch power to the ballast.

General Notes
• Typical dimming/switching legs shown.
• Do not remove bypass jumpers until after load wiring has been verified.
Wire sizes for power feed, to each input
• Power feed: #14 AWG (2.5 mm
2
) to #10 AWG (4.0 mm
2
)
• Neutral feed: #14 AWG (2.5 mm
2
) to #10 AWG (4.0 mm

)
Wire sizes for load wiring, from each output
• Dimmed hot (live): #14 AWG (2.5 mm
2
) to #10 AWG (4.0 mm
2
)
• Load neutral: #14 AWG (2.5 mm
2
) to #10 AWG (4.0 mm

Control Circuit Power
• Supplies power for internal operation.
• Requires dedicated feed with same voltage and phase as panel.
• Must be 1/4 in. (6 mm) away from PELV (Class 2: USA) control wiring
harness.
• Panel voltage (see pages 2-3) indicates feed voltage.
• For 230 V
and 240 V
panels, “Hot” is referred to as “Live”.
Therefore, terminals will be labeled L and DL.
See terminal block
modules for
specific wiring
details.
