3. Precautions:
• This unit is designed for office/lab environment and not for harsh industrial conditions. Also as an open-
chassis electrical system, all the usual precautions for these devices are expected accordingly. Any conductive
liquid spills, tool drops, wiring shortages, heavy physical blows or extensive electrostatic discharges can
cause damage to it and/or its connected accessories. However due to the applied precautions in its design,
these damages might be very limited and easily repairable while other modules keep on functioning properly.
• There is no level of electrical isolation in this unit and as soon as any control card gets connected to this unit,
it loses its isolation barriers. This is for ease of operation, probing, lowering the costs, etc. This is done as to
the application and purpose of the unit, which is not definitely industrial control. There are only two
isolated/unregulated IP5/IG5 and IP12/IG12 voltage sources, accessible through test points on J1. Only
mounting I/O terminal cards and providing external 24VDC/AC level commands, will revive this isolation.
• The external access port-EAP pins are all protected against static and dynamic HV/HC/HF interferences but
still applying wrong signals or shorting might interfere with the unit logic and cause invalid reactions and/or
readings. Please refer to this manual for the appropriate probing and signal applications for each pin.
• The power supply pins provided to the user at J1 test points and J8-EAP, are all current-limited to 80mA.
Any loading more than 100mA, may cause damage to the protective current-limiting resistors and the unit.
• There are no high voltages above 24VDC present on this unit anywhere except the components and power
supply module inside the grounded chassis, which carry the Mains voltage. Care should be taken to use the
provided grounded AC-cord and outlets in order to have full ground protection of the unit.
• Control cards G7/E7/F7 and G5/PS5 have their own connector on the unit. Please refer to the labels next to
each connector, before doing any wiring to the control cards (G7/E7/F7 to J9 and G5/PS5 to J10). Depending
on their screw hole positions, you can use the provided spacers to mount them on the unit.
