Soldering the variable resister terminals and the lead wires
1. Guide the lead wires through the terminal hole and loop them two to three times.
2. Solder the lead wires to the terminal (Soldering condition: 235 °C (455 °F), less than 5 sec).
3. Cover a heat-shrinkable tube over the soldered part to insulate.

6.7 Installing and wiring in compliance with EMC Directive
The
BLV
Series has been designed and manufactured to be incorporated in equipment. The EMC Directive requires
that your mechanical equipment in which the product is installed satises the applicable requirements.
The installation and wiring methods of the motor and driver explained here represent the basic methods that are
eective in helping your mechanical equipment conform to the EMC Directive.
The nal level of conformance of your mechanical equipment to the EMC Directive will vary depending on such
factors as the control system equipment used with the motor and driver, conguration of electrical parts, wiring,
layout and hazard level. It therefore must be veried through conducting EMC measures on your mechanical
equipment.

Applicable standards
EMI Emission Tests EN 55011 group1 class A, EN 61000-6-4
EMS Immunity Tests EN 61000-6-2
Caution: This equipment is not intended for use in residential environments nor for use on a low-voltage public
network supplied in residential premises, and it may not provide adequate protection to radio reception
interference in such environments.
Eective measures must be taken against the EMI that the
BLV
Series may give to adjacent control-system equipment,
as well as the EMS of the
BLV
Series itself, in order to prevent a serious functional impediment in the machinery.
The use of the following installation and wiring methods will enable the
BLV
to be compliant with the EMC Directive.

Wiring the power supply cable and signal cable
•
Use a shielded cable of AWG 16 to 10 (1.25 to 6 mm
2
) in diameter for the power supply cable and keep it as short as
possible.
•
Use a shielded cable for the I/O signals cable, and keep it as short as possible.
•
Strip a part of the shielded cable and ground the stripped part using a metal cable clamp that contacts the stripped
cable around its entire circumference, or use a drain wire to make the ground connection.
•
Attach a cable clamp as close to the end of the cable as possible, and connect it as shown in the gure.
