4.3.2 Electrostatic discharge (ESD) considerations
N O T I C E
Potential Instrument Damage. Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
Refer to the steps in this procedure to prevent ESD damage to the instrument:
• Touch an earth-grounded metal surface such as the chassis of an instrument, a metal conduit or
pipe to discharge static electricity from the body.
• Avoid excessive movement. Transport static-sensitive components in anti-static containers or
packages.
• Wear a wrist strap connected by a wire to earth ground.
• Work in a static-safe area with anti-static floor pads and work bench pads.
4.3.3 Power connections
D A N G E R
Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
D A N G E R
Electrocution hazard. Always remove power to the instrument before making electrical connections.
If the controller does not have an installed power cord, connect power with conduit or a power cord.
Refer to the sections that follow to connect power with conduit or a power cord.
4.3.3.1 Open the controller cover
Open the controller cover to get access to the wiring connections. Refer to Figure 7.
Figure 7 Open the controller
4.3.3.2 Remove the high-voltage barrier
High-voltage wiring for the controller is located behind a high-voltage barrier in the controller
enclosure. Do not remove the barrier while power is supplied to the controller. Make sure that the
barrier is installed before power is supplied to the controller.
