Electrical Connections

See Figure 3.

Wiring Requirements

NOTE: Use 18AWG shielded wire such as Belden #8770 for the driver-to-gun electrical connections. Use 16−18 AWG wire rated for at least

250 volts for the driver power connections. At a minimum, this wire must be suitable for 10 _C (50 _F) above the surrounding ambient temperature.

All driver wiring is connected to an 18-station terminal connector plugged into the receptacle on the backplane.

AC Input Power

1. Connect the power supply line wires to L1 and L2.

2. Connect the ground wire to the power input ground.

Trigger Signals

NOTE: Check for proper polarity when connecting trigger signal wires.

1. Connect the trigger input wires from the timer(s) to the TRIG 1

CHANNEL 1 (and TRIG 2 CHANNEL 2, if used) terminals:

S

For +15−48 Vdc trigger voltages, connect the input wires to + HI and

COM.

S

For 3−7 Vdc trigger voltage, connect the input wires to + L0 and

COM.

Spray Gun Connections

The spray gun coil connections are not polarity sensitive. Connect the MEG driver to the spray gun(s) as shown in the wiring diagram. Refer to your spray gun manual for wiring and fusing requirements.
