Precautions
1. The system-matched power box is exclusive for GSK983Ma. Do NOT supply this power to
other devices (such as brake and magnetic valve); otherwise, serious danger may occur!
2. Requirements for electrical cabinet
The electrical cabinet adopts full-enclosed structure and dustproof design. The temperature
difference between outside and inside of the cabinet should be less than 10℃; or, a heat-exchange
system should be installed. The ambient temperature should not exceed 45℃. Prevent the entry of
dust, coolant and organic solution.
3. Grounding
The cabinet should be protectively grounded, and the continuity should meet the requirement of
GB5226.1-2002. Well grounding is the essential condition for a stable operation. The grounding wires
of different parts cannot be connected with each other in series; rather, the protective grounding
terminals should be connected to grounding strip with yellow-green wires independently. The
grounding strip mentioned here is installed in the cabinet and the thickness is not less than 3mm ; its
grounding resistance should be less than 0.1Ω.
4. The system power should be supplied through isolation transformer.

5. Wiring
The joints between wires and the system or drive unit should be tight and firm. The low-current
type wires such as signal wires and control wires should be laid far away from heavy current and
electromagnetic interference, and be arranged in an uncurled manner as far as possible, because
winding annularly could easily cause the acquisition of interference signal.
6. Interference suppression
Connect the RC circuits at the two ends of AC coil in parallel. The RC circuits should be closed to
inductive load as far as possible. Connect FWD at the ends of DC coil reversely in parallel. Connect
the surge absorber at the winding head of AC motor.
