4. Preparing for Installation

4.1. Marking

HKC Logo / Trade mark
Model
Switches type
Enclosure type & Cert No. for flame proof:

Ambient temperature
Serial No.
Manufacturred year & month (YY-MM)
Cable entry size
Warning letter
Maker address

4.2. Pre-Installation for use in

potentially explosive atmosphere

Installation, commissioning, maintenance, repairs and modification work must only be performed by
qualified personnel with extensive knowledge on how to work explosion-proof electrical equipment.

Warning : Read this installation and maintenance manual carefully and completely Before attempting
to install, operate, or troubleshoot the HKC product.

4.2.1. Cable Connection

① Sealing devices must be used and shall be fitted directly at enclosure wall when using conduit.
② Cable glands shall be suitable for the environment and shall be certified as flameproof it used in

Zone 1 application.

③ Cable glands and shall be installed minimum 6 full threads and the length of thread is minimum

8mm.

④ The temperature at cable entry and blanching point may exceed 70℃ and 80℃ respectively

therefore select the appropriate cable gland and min 2SQ of wire is recommended when you install”

⑤ For cable entries or conduit entries that are not used, user or installer shall close by certified

blanking elements(stopping plugs) so that the flameproof properties of the enclosure are
maintained.

4.2.2. Groundings

① Always ground the enclosure in accordance with local electric codes. The most effective enclosure

grounding method is a direct. Connection to earth ground with minimal impedance. Methods for
grounding the enclosure include:
Internal ground connection : The internal ground is located inside the body.
External ground connection : The ground bracket is located on the side of body.

(Min 2SQ wire required)

4.2.3. Special Condition for safe use

① Electrostatic discharge from window(over 1GΩ) may cause the ignition on the explosive gas

atmosphere. By adapting the conducting window bolts make reduce the risk from electrostatic
discharge.

② Before installation or maintenance products, shut off incoming power and grounding should be

connected.

4.3. Initial inspection

When the user receipts the product, inspect the condition of the product and ensure the name plate
comparing with order sheet.

4.3.1. Remove packing wrap or wooden box carefully. Inspect the product for any physical damage that
may have occurred during shipment.

4.3.2. Check the product specification with product ordered. If a wrong product has been shipped,
immediately inform to our coordinator.
