Mains connected load of BT356 card
racks partially equipped with tightening
channels
If the card racks are not fully equipped, the
mains connected load can be configured in
accordance with the following table.
For connected loads up to 1250 VA, the
connection can be 1-phase (Table 3).
We recommend a 3-phase connection via a
network transformer for higher powers
(Tab. 4).

Card rack equipment
A tightening channel consists of the following
components:
• Stationary tightening spindle or ErgoSpin
hand-held nutrunner with connection cable
• Controller
• Servo amplifier
If the appropriate control and servo
components are installed, both stationary
tightening spindles and ErgoSpin hand-held
nutrunners can be connected to and
operated on the BT356 card rack. Mixed
operation of stationary tightening spindles
and ErgoSpin hand-held nutrunners on a
BT356 is possible at any time.
The maximum permissible peak current for up
to six tightening channels in the card rack is
140 ampere. This is why you may only install
components with a power consumption that
does not exceed a total of 140 ampere.
Total power consumption (tightening
spindles + ErgoSpin) ≤ 140 A
