6.2 Control Supply
Voltage must be connected to the TMS7 control voltage
terminals. The required control voltage is dependent upon the
TMS7 model ordered.
• TMS7xxxx-xx-C24-xx models: 230VAC (A2-A3) or 400VAC
(A1-A2)
• TMS7xxxx-xx-C45-xx models: 460VAC (A1-A2) or 575VAC
(A2-A3)
TMS7 Model Maximum VA
TMS7-4007~TMS7-4022 11VA
TMS7-4030~TMS7-4055 18VA
TMS7-4075~TMS7-4110 24VA
TMS7-4132~TMS7-4500 41VA
TMS7-4600~TMS7-4800 56VA
For circumstances where the available control supply voltage is
not suitable for direct connection to the TMS7 the following
range of auto-transformers are available as accessories. These
auto-transformers can be mounted within the TMS7 in models.

6.3 Control Wiring
TMS7 operation can be controlled using either the local push
buttons, remote control inputs or the serial communications link.
The <LOCAL/REMOTE> push button can be used to switch
between local and remote control. Refer to Function 20.
Local/Remote Operation for details.
Remote Control Inputs
The TMS7 has four remote control inputs. Contacts used for
controlling these inputs should be low voltage, low current rated
(Gold flash or similar).

CAUTION
CAUTION:
Do not apply voltage to the control inputs. The
inputs are active 24VDC and must be controlled
with potential free circuits.
Ensure contacts/switches operating the control
inputs are suitable for low voltage, low current
switching ie, gold flash or similar.
Ensure cables to the control inputs are
segregated from AC power and control wiring.
Relay Outputs
The TMS7 provides four relay outputs, one fixed and three
programmable. Functionality of the programmable outputs is
determined by the settings of Functions 21, 22 & 23.
