Site survey

A qualified engineer must survey the

installation site to determine the

correct ground preparation for the size

and weight of the RTM-75kW user unit, in

accordance with local regulations.

The RTM-75kW user unit is best

installed following the recommended site

configuration requirements.

Ground fixing

The RTM-75kW user unit is to be fixed to

the ground through the baseplate

fixing holes with 4 x M16 fasteners.

Fasteners are not supplied, because the

type required depends on the foundation

used and must be chosen by the installer

accordingly.

The fasteners should fix the RTM-75kW

user unit securely to the foundation

through the baseplate in accordance with

the dimensions and fixing points shown in

Base plate dimensions.

Note:

Keep the plastic inserts from the

bolts for use in the baseplate holes.

Conduit requirement

Up to Ø 110mm OD conduit maximum.

Ø50 and Ø25mm conduit standard.

Foundation requirements

The foundation must be flat, even, and

have the appropriate density for the

weight of the user unit.

Check the flatness and level of the

foundation and level of the RTM-75kW

user unit baseplate prior to fixing.

Communications

Wired ethernet or 3G/4G network

capability.

Power supply

The RTM-75kW user unit is designed to

accommodate input wiring from either an

underground foundation or above ground.

High power (HP) input wiring

High power input wiring can be provided

to the charger in three different

scenarios:

1. A single multi-conductor cable

Ø27-38mm to suit the supplied M50

cable gland.

2. Running the wiring in a 50mm conduit

and installing using the provided M50

conduit adaptor and seal.

3. Individual wires can be used with the

provided alternate gland plate and 4x

M32 cable glands. Each individual cable

must be Ø13-18mm.

Auxiliary field wiring

The auxiliary field wire must be a single

multi-conductor cable Ø10 - 14mm, to

use the supplied M25 cable gland.

If the auxiliary wire is smaller than Ø10

the 25mm conduit installation must be

used.

CRITICAL

It is critical to product safety and

warranty that IP65 is achieved for

all input wiring.
