(3)Install at the ambient temperature ranged 0~45℃.

(4)Secure sufficient space for the easier disassembly and maintenance.

(5)Install safety fence with a gate, and prohibit any person from entering the robot's working envelope.

(6)Remove any obstacles out of the robot’s working envelope.

(7)Take a special measure, considering thermodynamics of controller, if the robot is installed near the heating elements or places exposed directly to the sun.

(8)Take a special measure if the robot is installed in a place of abundant dust such as metal powder in the air.

(9)Install the robot not to transmit welding electric current. (In other word, insulate SPOT GUN with/from the robot’s wrist.)

(10)Grounding is very critical in preventing electric shock and malfunction caused by noise, and thus install as following instructions.

①Install an exclusive grounding terminal using class 3 or higher. (For the input voltage of 400V of higher, use special class 3 or higher.)

②Connect grounding line into the grounding bus-bar inside of the control panel.

③In case of direct grounding on the floor by anchoring, two-point grounding both by robot manipulator and by controller can produce a “ground loop” and contrariwise cause abnormal operation. In this case, connect the grounding line to the base of robot manipulator and disconnect the second grounding point to the controller. If the robot vibrates even after stopping, double-check the grounding status because the possible main causes could be an incomplete grounding or “ground loop” .

④In the use of internal transgun(GUN), there is a possible danger of dropping because the primary power cable is directly connected to the spot gun. In this case, directly connect the grounding line to the base of robot manipulator in order to prevent any electric shock and protect the control panel, but do not connect it to the controller.
