Cooling

Vents at the top and bottom of the G123-814 chassis provide cooling for internal electronic equipment. 

These vents should be kept clear.

It is important to ensure that the equipment below does not generate

hot exhaust gases that could heat the G123-814.

Wiring

It is recommended that crimped “guide lace sleeves” be used as screw terminals. 

Allow sufficient length of cable

so that the wires remain connected when the circuit card is removed from the housing. 

This allows the circuitry to be checked while the circuit card is still connected and operational.

For cables connected to the outside of the housing as well as for

cables connected to the adjacent DIN rail unit, an additional 100 mm is sufficient.

The cable to the valve coil carries 1 Amp and should be sized accordingly.

Cables with a conductor size of 0.2 mm2 are normally rated at 1 Amp and are suitable for cable lengths

up to 5 metres.
