Compliance to European EC Directives
1. European EC Directives
The European EC Directives were issued to unify Standards within the EU Community and to smooth
the distribution of products of which the safety is guaranteed. In the EU Community, the attachment of
a CE mark (CE marking) to the product being sold is mandatory to indicate that the basic safety
conditions of the Machine Directives (issued Jan. 1995), EMC Directives (issued Jan. 1996) and the
Low-voltage Directives (issued Jan. 1997) are satisfied. The machines and devices in which the servo
and spindle are assembled are a target for CE marking.
The spindle is a component designed not to function as a single unit but to be used with a combination
of machines and devices. Thus, it is not subject to the EMC Directives, and instead the machines and
devices in which the spindle is assembled are targeted.
This spindle complies with the Standards related to the Low-voltage Directives in order to make CE
marking of the assembled machines and devices easier. The EMC INSTALLATION GUIDELINES
(BNP-B8582-45) which explain the spindle amplifier installation method and control panel
manufacturing method, etc., has been prepared to make compliance to the EMC Directives easier.

2. Cautions of compliance
Use the standard spindle amplifier and EN Standards compliance part for the spindle motor. In
addition to the items described in this instruction manual, observe the items described below.
(1) Environment
The spindle amplifier must be used within an environment having a Pollution Class of 2 or more
as stipulated in the IEC664. For this, install the spindle amplifier in a control panel having a
structure (IP54) into which water, oil, carbon and dust cannot enter.
(2) Power supply
① The spindle amplifier must be used with the overvoltage category II conditions stipulated in
IEC664. For this, prepare a reinforced insulated transformer that is IEC or EN Standards
complying at the power input section.
② When supplying the interface power supply from an external source, use a 24 VDC power
supply of which the input and output have been reinforced insulated.
(3) Installation
① To prevent electric shocks, always connect the spindle amplifier protective earth (PE) terminal
(terminal with
② When connecting the earthing wire to the protective earth (PE) terminal, do not tighten the wire
terminals together. Always connect one wire to one terminal.
(4) Wiring
① Always use solderless terminals with insulation tubes
so that the wires connected to the spindle amplifier
terminal block do not contact the neighboring
terminals.
