OPERATING INSTRUCTIONS

Installation Area

Do not install the EC2B control box in an environment where more than IP65 protection degree
(more than Type 4X in North America) is required.

Use the EC2B control box under ambient temperature of –20 to +50°C. If the control box is
exposed to direct sunlight and the surface temperature may rise above 50°C, provide a shade to
keep the surface temperature below 50°C.

Installation

Use four M6 bolts for 1-column, four M8 bolts for 2- and 3-column, or other methods with
equivalent strength to install the control box. Mounting tab thickness is 1.5mm for 1 column and
2mm for 2, 3, and 4 columns.

• If bolts become may loose due to vibration, use spring washers.

• If bolt corrosion is anticipated, use anti-corrosion bolts or other countermeasures.

Notes on Emergency Stop Switches

When using the emergency stop switches on safety-related parts of the control system, observe
safety standards and regulations of the relevant country or region. Also be sure to perform a risk
assessment before operation.

Opening/Closing the Lid

Use a Philips screwdriver to loosen lid mounting screws. While holding the unhinged side, open
the lid slowly without exerting excessive force on the hinge.

Before closing the lid, make sure of the following:

• No foreign substances are on the packing or joint surfaces.

• No displacement of the waterproof packing.

• Wires are not caught between the joint surfaces.

• Next, close the lid slowly and tighten the screws to a proper torque of 1.6 to 2.4 N·m.

Limitation of the Operating Current

Major heat sources comes from the wiring which is connected to the control box. Therefore,
not only the operating current but wiring conditions (size, no. of wires, no. of wire bundles) may
cause temperature rise. When wiring, observe the following conditions.

Stranded wire: 1.5 to 2.5 mm2 (UL-c-UL certified) / Solid wire: ø1.2 to ø1.6 mm (16 to 14 AWG)

• Maximum no. of wires per bundle: 16

• Maximum operating current: 10A
When using the control box under an operating environment of 40°C minimum, use a heat
resistant cable of 70°C minimum.
