Heating Power

Table 12 below lists the power supply requirements of each WMT700

heating option.

Table 12 Heating Power Supply Requirements for WMT700

Series

Heating Option Heating Voltage Required Heating

Power Supply

Table 13 below lists the required dimensions for the heating supply

cabling, if extension is needed.

Table 13 Required Dimensions for Heating Supply Extension

Cabling

Cable Length Minimum Dimensions (Total Cross-Section)

< 3 m/10 ft 0.25 mm

/AWG23

< 10 m/30 ft 0.5 mm

/AWG20

>10 m/30 ft 1 mm

/AWG17

In power-critical environments the power consumption of WMT700 can

be significantly reduced by using the low-power mode.

CAUTION

There are two terminals connected in parallel for both positive and

negative rails of the heating voltage for the maximum current capacity. In

case the connection cable has parallel supply wires, they all have to be

connected to ensure current capacity. Leaving one terminal unconnected

or connecting it to the ground may cause a WMT700 malfunction or a

short circuit in the power supply.

NOTE

Always use cables that meet the minimum dimension requirements. Long

cables with thin wires cause power losses in the cable and significantly

decrease the heating capabilities of WMT700.
