INSTALLATION INFORMATION
MOTOR
1) Ensure motor is mechanically secure and mounted according to manufacturers
specifications and practice.
2) Inspect brush gear, ensure commutator is in good condition and brushes are free to move
in brush box and in good condition.
3) Check obstructions in motor vents to maintain cooling air path.
4) Ensure motor armature choke (if specified) is correctly wired.
5) Ensure motor is free to rotate and that pulleys and couplings are correctly aligned.
6) Ensure transit damage has not occurred to motor windings or connections. Disconnect the
controller before carrying out electrical measurement e.g. insulation resistance.
ELECTRICAL INSTALLATION
RECOMMENDATIONS
1) Although the controller is designed to provide double or reinforced insulation between the
user and bare live parts, it is recommended that the "0v/Signal Ground" is earthed. Where
a number of controllers are used in a system the "0v/Signal Ground" terminals should be
grounded together and earthed at one point.
2) The controller is designed for armature current form factor of 1.5 or less. It is
recommended that a armature choke be fitted where a form factor of less than 1.5 current
cannot be guaranteed.
3) Due to the earth leakage currents the controller and filter should be permanently earthed.
This can be achieved by either connecting two earthing conductors of the required value,
see table 3.1, or connecting one earthing conductor of at least 10mm
4) Unused Analogue Inputs should be "grounded" (i.e., connected to 0V/Signal Ground) to
eliminate interference.
WIRING
1) Control cabling 0.75sq.mm minimum.
Auxiliary supply cable
Field cable
2) Power cable to be minimum 600VAC rated at 1.5 x armature current.
3) High speed semi-conductor fuses of the correct rating are recommended for incoming
supply protection. The 514C is not internally fused.
4) Ensure a protective earth connection is made compatible with the rating.
5) Isolated control wiring should not be run close to the power cabling. If screened cables
are used (recommended on setpoints and tachogenerators) connect screens to earth only at
controller end.
6) Parker Hannifin Manufacturing Limited can supply fuse assemblies which can be
bulkhead mounted and also act as convenient supply isolators.
