4.2 Electrical installation

Destruction of parts of equipment and loss of regulation control
` All lines for connecting the wire-actuated encoder must be shielded.
` Current linkage: don't connected or removed live.
` Perform wiring work in the de-energized state only.
` Use strands with suitable ferrules.
` Wiring to the screen and ground (0 V) must be secured to a good
point. Ensure that the connection of the screen and earth is made to a
large surface area with a sound connection to minimise impedance.
` Prior to switching on check all mains and plug connections.
` Switch on operating voltage together with downstream electronics (e.
g., control unit).
Basically, all connections are protected against external interference.
Choose a place of operation that excludes inductive or capacitive interfer-
ence influences on the wire-actuated encoder. When mounting the system
keep a maximum possible distance from lines loaded with interference. If
necessary, provide additional installations including screening shields or
metallized housings. Contactor coils must be linked with spark suppres-
sion.
Admissible power input
Supply for the wire-actuated encoder shall be sized sufficiently. When
accelerating, power input may be higher than nominal current for a short
period. The voltage values are a function of the device design and can be
referred to in the technical data in chapter 9.
