2.5 Terminal box
Wiring with "d" terminal box
• Terminal box is arranged according to the
feet (for IM1... or IM2... mounting).
The terminal box axis is normally perpen-
dicular to the laying surface.
Optionally, it can be supplied for "right" or
"left" mount according to a front view of
the motor, main shaft end side (without
surcharge).
Note: the terminal box position can only
be changed at the factory.
• Cable output position
In standard executions, the cable output is
on the right (looking at the motor from the
shaft side).
All other options must be requested at the
time of the order using the same reference
(upper, lower, left, right, front and rear
cable output).
• "d" cable gland
In "EEx-d" motors, the cable gland aids
the flameproof enclosure closing.
The user MUST choose a cable with a
diameter on the sealing membrane side
corresponding to the cable gland specifi-
cation, as well as use a device for hooking
the cable on the cable external diameter
side.
In standard conditions, motors are sup-
plied with an EEx-d cable gland with cable
hook.
On the sealing membrane side, the cable
must have a diameter of 11 ± 0.5 mm
(Figure 2 C).
In standard conditions, 2-speed motors
have two cable glands.
