3.2.20 Power supply circuitry
The MAC800/1200 supply is split into 2 individual circuits with full galvanic isolation be-
tween the circuits. The control circuitry requires a voltage in the range 18 to 32VDC and
the power circuity must be supplied with 90 to 240VAC (Set by solder jumper
115V supply voltage (MAC800/1200), page
fers the feature that the supply voltage for the power circuitry (90-240VAC) can be re-
moved for safety reasons, while the control circuitry can continue operating and thus
keep the position counter updated and keep other vital functions such as communication
active.
P+/- must be per-
manently connected
if control circuitry
must be keept active
while main power is
disconnected.

The circuit above is shown with an emergency relay (box) which can be omitted if the
application does not require this safety feature. There are shown examples of Emergency
stop and relay in
intended to cover 90% of all applications, but if the error message "overvoltage" is mon-
itored, an external power dump resistor must be connected between the terminals PD
and BO.
3.2.21 Emergency stop
Please consult the chapter:
3.2.22 Sizing the external fuse (Prefuse).
When using 115V supply voltage:
To met UL requirements, the prefuse must be a class RK5 such as the type FRN-R-15
(15Amp.) from manufacturer: Cooper Bussmann INC.
When using 230V supply voltage:
Prefuse T10A@230VAC type gG, Do or Dz in the phase line Rated for600V/150kA.
