Cautions for Installation

Observe the safety instructions described in this section when installing the system.
Installation should be done in accordance with the applicable local electric codes.

Before Installing

Before starting the installation, ensure the following:

Post "warning" signs in areas where high-voltage cables are installed.

Post "off limit" signs in areas where accidents are most expected.

Use guardrails or fences to block open areas such as ditches, open roof areas,
and scaffolds.
Install the system in the restricted access area.

While Installing

During installation, ensure the following:
The system power must be cut off before installing.
Ensure that the main switch of the power supply is off when installing the system.
Installing the system with power on may cause system damage or fatal human
injury when connecting or disconnecting cables.
Ensure that the workers wear protection gloves and goggles to prevent injury from
debris while drilling holes in a wall or ceiling.
Do not wear accessories such as watches and rings to prevent electrical shock.
Cover unused ports with a cap. This prevents foreign substances entering into the
unused ports.
To prevent foreign substances, outdoor air, and moisture entering into the cable
inlet (including cable gland and conduit), finish the cable inlet as follows:
- Unused inlet: Use the hole finishing materials including cap and rubber packing.
- Cable-installed inlet: After cable installation, block any space in the inlet with the
tape, compressed sponge, rubber packing, and silicone.
When operator installs the MMU, the MMU must be within the protective angle
(left/right side 45° each from the central axis) to prevent the MMU from lightning
damage.
