Commissioning Procedures 3-9

10. When each gate driver circuit has been checked, disconnect the power
supply and remove it from the cabinet.
NOTE: Systems with optional Pump Control or Soft Stop include
continuous gate drive power supplies (IGDPS); therefore, step 10 does not
apply.
The gate-drive circuits operate at high voltage when the
SMC is energized. Failure to remove the portable test
power supply will result in equipment damage and may
cause severe injury or death.
11. Open the switch DIP1 on the interface board (see Figure 3.2) before
returning the unit to service.
If the DIP1 switch is not in the open position when the
SMC is energized, the motor will start in an uncontrolled
manner and may cause severe damage.
12. Check that all plugs and connectors are secure. Retrieve all hardware
and tools from the equipment. Replace and secure any barriers
removed during servicing and close all doors before applying power.
Servicing energized industrial control equipment can be
hazardous. Severe injury or death can result from
electrical shock, burn, or unintended actuation of
controlled equipment. Recommended practice is to
disconnect and lock out control equipment from power
sources, and allow any stored energy in capacitors to
dissipate. The safety related work practices of NFPA
70E, Electrical Safety Requirements for Employee
Workplaces, must be followed if it is necessary to work
in the vicinity of energized equipment.
1. Apply rated control voltage to the control circuit.
2. Using the control schematic, apply control signals to cause relays and
contactors to energize, to verify operation.
3. Remove any jumpers used in the test and restore all circuits to normal
when finished.
